CNC metal fabrication is replacing other manufacturing techniques in several industries. The medical field is considered to be one where mistakes are rare, and the same rules apply when manufacturing medical parts, as the field is concerned with human life, and even small mistakes can lead to serious health problems or even death. As a result, the machining techniques used by machinists to produce medical parts must support tight tolerances and high-precision measurements. CNC metalworking is growing in popularity because of its ability to produce detailed and accurate results in large quantities, which has led to an increase in the number of manufacturers using CNC machines in the industry. CNC machining is a manufacturing method in which tool movement is controlled by pre-programmed computer software. All medical products can be manufactured accurately and quickly with the help of CNC milling and turning. Let's look at the main advantages that create demand for CNC machining in the medical industry: No fixed tools CNC machining is unmatched in terms of quick turnaround and minimal investment in small production runs or even one-off products. Parts for the medical industry must often be manufactured quickly and in small batches. At the same time, CNC metalworking allows parts to be manufactured without specialized tooling, which can lengthen the manufacturing process but provide excellent quality and precision even without tools. No quantity limitations After creating a digital CAD (Computer Aided Design) file, you can easily build a cutting program from it with the push of a button. The coding application allows for the manufacture of individual parts or any number of parts with the highest degree of precision and accuracy. This is a huge benefit when creating one-off or one-off custom parts such as highly specialized medical devices, appliances, equipment, prosthetics and other medical or surgical products. While other programs require a minimum order quantity to obtain the required raw materials, making it impractical for some projects, CNC machining does not require a minimum order quantity. High Tolerances Many medical types of equipment require a large range of tolerances, and with CNC machines, this is easy to achieve. Surface finishes are often very good and require minimal post-processing, saving time and money, but this is not the most important consideration. In general, the most important thing to remember about medical supplies and equipment is that they must be fit for their purpose and any deviation from the standard can mean disaster. Fast Machines CNC machines are faster and can work 24 hours a day, 365 days a year. Aside from routine maintenance, repairs and upgrades are the only time manufacturers stop using their equipment. Digital CAD files are lightweight and flexible Product designers, medical experts and manufacturing professionals can quickly and easily transfer digital programs from one location to another. This technology significantly enhances CNC machining capabilities to produce high-quality, specialized medical devices and equipment solutions regardless of geographic location and whenever and wherever they are needed.This feature of CNC machining comes in handy, especially in time-critical medical environments.

Wear-resistant nylon materials are mainly used to reduce the coefficient of friction or wear of nylon by adding wear-resistant additives such as carbon fibers, molybdenum disulfide, graphite, PTFE powder or silicone powder to nylon, and the dosage of these additives is generally between 3% and 15%. Generally speaking, wear-resistant nylon is mainly used in the field of mechanical parts for manufacturing various wear-resistant products (injection molding method), such as bearing cages, bushings, friction-reducing rings, friction-reducing pads and so on. In recent years, wear-resistant nylon has been widely used in the automotive field. Compared with pure nylon resin, wear-resistant nylon has lower coefficient of friction, better wear resistance and self-lubrication, as well as high mechanical properties and good heat, oil and chemical resistance, it also greatly reduces the water absorption and shrinkage of raw materials. There are many improved varieties of self-lubricating wear-resistant nylon, such as graphite nylon PA12, graphite nylon PA66, graphite nylon PA12, carbon fiber nylon, nylon/molybdenum disulfide, nylon/polytetrafluoroethylene and nylon 1010/molybdenum disulfide. Graphite nylon is particularly suitable for wear-resistant lubricant materials, this is because graphite is often used as a lubricant in the mechanical industry, lubricants can not be used at high speed, high temperature and high pressure, while graphite wear-resistant materials can slide at high speeds of 200 ~ 2000 ℃, working without lubricant, graphite materials are widely used in many equipment that conveys corrosive media, such as piston cups, seals and bearings, operation without adding lubricant, graphite emulsion is also a good lubricant for many metal processing. However, certain mechanical parts (e.g., shims used for transmission gears) have high requirements for accuracy in the thickness direction, thus placing stringent requirements on the uniformity of the nylon material in the thickness direction. Conventional wear-resistant nylon products are prone to a concave effect on the end face due to heat shrinkage and other factors. In particular, the large dimensional difference between core shrinkage and edge shrinkage of thick parts is a prominent problem and can only be used after targeted improvements. This is also the difficulty of technical realization, that is, how to improve the dimensional accuracy of the product on the basis of ensuring the wear-resistant effect, and the cost is not too high. Several commonly used wear-resistant additives (1) Carbon fiber Carbon fiber can significantly improve the integrity of the material structure, load resistance and wear resistance. And glass fiber is different from carbon fiber is a softer and less scratchy fiber, carbon fiber will not scratch its friction with the friction of iron or steel friction surface. (2) Molybdenum disulfide Molybdenum disulfide is a wear-resistant additive mainly used in nylon plastics. Molybdenum disulfide acts as a crystallizing agent to increase the crystallinity of nylon, creating a harder and more wear-resistant surface. Molybdenum disulfide has a high affinity for metals. Once adsorbed on a metal surface, the molecules of molybdenum disulfide will fill the pores on the metal surface that can only be seen with a microscope and will make the metal surface smoother, which makes molybdenum disulfide an ideal wear-resistant additive for applications in which the nylon and the metal rub against each other. (3) Graphite The chemical structure of graphite is a unique lattice structure, this unique chemical structure makes the graphite molecules in the very small friction will easily slide each other, this wear-resistant properties in the water environment is particularly important, so graphite as an ideal wear-resistant additives used in a lot of parts placed in the water, such as the water store shells, blades and so on. (4) Polytetrafluoroethylene (PTFE) PTFE has a low coefficient of friction, and during friction PTFE molecules form a lubricating film on the surface of the part. PTFE has excellent lubrication and wear resistance under friction, and is the optimal wear additive in high-load applications. These high-load applications include hydraulic piston ring seals, thrust washers. PTFE content in non-crystalline plastics is generally 15%, while in crystalline plastics is generally 20%. (5) Silicone Silicone, the scientific name is generally called polysiloxane (or polydimethylsiloxane), low molecular weight polysiloxane liquid commonly known as silicone oil, ultra-high molecular weight polysiloxane appearance of white particles or powder, mainly used as a plastics processing aids, to overcome the traditional silicone oil processing troubles and performance shortcomings, which can significantly reduce the coefficient of friction of plastics to improve the slipperiness, to improve the surface luster, improve the resistance to scratches, and at the same time, have a good stability and non-migration. Good stability and non-migration.

This characteristic of engineering plastics is important for vehicles, ships, airplanes and other machinery and equipment that need to reduce self-weight. 2. Specific Strength: For equal volumes of material, engineering plastics are generally less strong than metals. However, when compared with equal weight, because engineering plastics are much lighter than metal, some engineering plastics have much higher strength than general metal, which is the higher strength of existing structural materials. For example, the modified reinforced PPS has good stiffness, and the product has the ringing sound of metal when it falls to the ground. 3. Good chemical stability: engineering plastics generally have good corrosion resistance to acids, alkalis and other chemicals, which is a very obvious advantage.

Therefore, the application of engineering plastics in the motor, electronic and electrical industry has an extremely broad prospect. 5. Friction reduction, good abrasion resistance: using this characteristic, engineering plastics can be used to manufacture a variety of self-lubricating bearings, gears and seals, etc.. Engineering plastics also has excellent foreign matter buried performance, used in the presence of abrasive particles or impurities in harsh conditions is particularly important. 6. Good vibration damping and muffling effect: machinery equipped with engineering plastics bearings and gears can reduce vibration, noise reduction and even muffling. 7. Easy molding and processing: engineering plastic products can often be molded at once, while metal products are always processed through several, dozens or even dozens of processes to complete. This feature of engineering plastics is important for saving working hours and improving labor productivity. In addition, engineering plastic products mechanical processing is relatively simple, stable size, low cost of molds, high yield. Commonly high temperature engineering plastics are divided into the following categories: fluoroplastic (Fluoroplastie), polyaryl ether ketone (PAEK) class, high temperature nylon, polyphenylene sulfide (PPS), polyimide (PI) class, polysulfone (PSU) class.

Nylon rod is an important engineering plastics, can replace the wear-resistant parts of mechanical equipment, instead of copper and alloy for equipment wear parts. It has good toughness, strong abrasion resistance, oil resistance, shock resistance, tensile and bending strength, and has the characteristics of small water absorption and good dimensional stability, thus it is used to process a variety of wear-resistant high-strength parts. In spite of this, there are some small details and method skills that we should learn when we carry out nylon bar lathe processing. Nylon bar lathe processing skills: 1, Processing less than 30mm small holes, due to small holes in the space is narrow, heat dissipation is difficult, operation of the lathe needs to reduce the lathe speed to 300 rpm or less, with cutting fluid to be cooled; slow, even speed into the drill, timely chip removal; through the hole, to the bottom of the hole, the drill bit will be penetrated, the need to be more careful, reduce the speed of drilling, cutting fluid or coolant, it must be uniformly sprayed to the position of the hole. 2, The processing of holes larger than 30mm, first of all, to sharpen the drill bit, easy to process, reduce the scrap rate; will reduce the lathe speed to 180 rpm or less, larger than 55mm holes, you can reduce the lathe speed to 60 rpm or so; slow, even speed into the drill, chip removal in time, spray sufficient cutting fluid; drill out of the hole, be careful, reduce the speed of drilling. 3, For small hole reaming processing, the lathe speed should be lower than 60 rpm; uniform, low speed into the drill, the operator must hold the tailstock handle, to prevent the drill bit was quickly brought into the hole by the lathe, resulting in the collapse of the product; cutting fluid spray evenly. 4, External round processing, processing tool selection of white steel tools, should not choose alloy tools, tools should be kept sharp; lathe speed of not less than 200 rpm; appropriate feed speed to improve processing accuracy and surface finish. Nylon bar is a widely used engineering plastics, almost all over the industrial field, widely used in chemical, mechanical, automotive, textile, scientific research and many other industries. It has light quality, corrosion resistance, low price and easy processing. It is unaffected by chemicals whether weak bases, alcohols and esters, carbonate compounds, oil and grease. Nylon sheet:Outstanding wear resistance, its coefficient of friction is usually 0.1-0.3 as phenolic plastic cloth 1/4, bar alloy 1/3 is an excellent self-lubricating material good mechanical properties. Its hardness is large, and has taught high tensile, flexural and impact strength and taught high extension, his compressive strength and metal is not comparable to its fatigue strength and cast iron and aluminum alloys at the same level. Stable chemical stability, it is unaffected by chemicals whether weak alkaline, alcohol fat, hydrocarbons, oil and grease.

Nylon products is a new type of engineering plastics, because of its excellent comprehensive performance, make it in the engineering plastics in the status of the rapid rise, become an important material, the use of the expanding, so what are the technical requirements of nylon processing parts? What are the factors affecting nylon processing parts? Technical requirements of nylon processing parts 1. Rheological properties of nylon Most of the nylon is crystalline resin, when the temperature exceeds its melting point, its melt viscosity is small, melt fluidity is very good, should prevent the occurrence of overflow. At the same time, due to the rapid condensation of the melt, the material should be prevented from blocking the nozzle, runner, gate and other products caused by the phenomenon of insufficient. Mould overflow value of 0.03, and the melt viscosity of the temperature and shear changes are more sensitive, but more sensitive to temperature, reduce the melt viscosity from the barrel temperature to start. 2. Water absorption and drying of nylon Nylon's water absorption is large, wet nylon in the molding process, the performance of a sharp drop in viscosity and mixed with bubbles appear on the surface of the product silver wire, the mechanical strength of the product decreased, so the material must be dry before processing. 3.Crystallization In addition to transparent nylon, nylon is mostly crystalline polymer, high crystallinity, product tensile strength, abrasion resistance, hardness, lubricity and other properties have been improved, the coefficient of thermal expansion and water absorption tends to decline, but on the transparency and impact resistance is not good. Mold temperature has a greater impact on crystallization, high mold temperature crystallinity is high, low mold temperature crystallinity is low. 4.Shrinkage Similar to other crystalline plastics, nylon resin shrinkage problem, the general shrinkage of nylon with the crystallization of the relationship between ******, when the crystallinity of the product products will increase the contraction of the product, in the molding process to reduce the mold temperature \ to increase the injection pressure \ to reduce the temperature will reduce the contraction of the product, but the products of the increase in the internal stress of the easy to deform. For example, non-glass fiber reinforced PA6 and PA66 shrinkage in 1.5-2%, after adding glass fiber can make the shrinkage rate reduced to 0.3% to 0.8%. 5. Molding equipment Nylon molding, the main attention to prevent "nozzle salivation phenomenon", so the processing of nylon materials generally use self-locking nozzle. In addition, it is best to choose the injection molding machine with a larger plasticizing capacity. 6. Products and molds Wall thickness of products Nylon flow length ratio of 150-200, nylon products wall thickness is not the bottom of 0.8mm in general between 1-3.2mm to choose from, and the contraction of products and products related to the wall thickness, the thicker the contraction of the wall thickness is greater. Factors affecting nylon machined parts 1.Clamping Usually, in the workpiece clamping, the clamping force will make the workpiece deformation, unloading clamping force, the workpiece elastic deformation automatically recover, resulting in the workpiece free of stress under the conditions of size and processing size is not the same. If the clamping force is too large, will exceed the yield limit of the material, a long time clamping will make the workpiece plastic deformation, after processing the clamped part of the part and the processing of the size does not match; on the other hand, it will lead to the clamping is not tight, the vibration of the machining process is large, affecting the final machining of the size of the quality. Nylon materials and metal materials are different in nature, with a small density, easy to deform and easy to process the characteristics of the clamping process, it is more likely to be deformed due to the clamping; processing is completed after the elasticity of the recovery, so that the size and shape of the changes, and the larger the clamping force, the greater the deformation after processing is completed. Therefore, in the nylon thin-walled parts processing, should be taken vigorously clamping primary processing, light clamping finishing processing order to ensure that the clamping force does not affect the size of the machining accuracy. 2.Cutting tool Cutting nylon material should avoid the tool itself to bring too much pressure, club cutting process in the constant movement to the inside of the material, in addition to the lateral cutting of the tool on the material, there is a direct propulsion pressure. If the propulsion pressure is too large, will not only affect the stability of the workpiece clamping, but also directly cause the deformation of the workpiece, resulting in the elastic deformation of the workpiece to recover after the size deviation is too large. Stiffness of the tool relative to the stiffness of the weak tool, its own elasticity is poor, more likely to produce the workpiece processing propulsion, resulting in workpiece color, so the use of relatively weak stiffness of the alloy knife machining accuracy is better. Edge of the sharpness of the degree of its machining accuracy has a considerable impact, the sharper the edge of the tool, the smaller the cutting resistance, the smaller the propulsive force on the material, the smaller the deformation of the workpiece, the smaller the rebound phenomenon, the better able to ensure the dimensional accuracy; therefore, the use of alloy knife processing nylon materials, triangular knife than the quadrangular knife is good and in the finishing of the workpiece, in the case of ensuring the roughness of the surface, the use of a new blade than the old blade is more able to Ensure dimensional accuracy, and even a certain amount of grinding can be carried out on the knife edge, so that the sharp angle of the knife edge becomes smaller. 3.Cutting heat A very important factor affecting the accuracy of workpiece processing is cutting heat. Parts processing will produce a lot of heat, such as milling elastic deformation and plastic deformation, chip separation and tool and workpiece friction consumed energy, most of which will be converted to thermal energy, and these thermal energy a small part of the chip away or air radiation, a large part of the workpiece is absorbed, these thermal energy in the formation of thermal stress within the workpiece, with the continuous advancement of the processing, and constantly generate thermal energy, thermal stress, and ultimately make the workpiece occur. With the continuous advancement of processing, heat energy is constantly generated and thermal stress is constantly changing, which ultimately makes the workpiece deformed, distorted, and even cracked. For nylon material, its own thermal stability is extremely weak, a little heat absorption, will lead to deformation. 4.Material original internal stress The workpiece material itself exists within the internal stress. In the machining process, due to the removal of excess parts, changing the overall structure of the workpiece correlation, resulting in the internal stress balance of the material is broken, the need to find a new balance of internal stresses, resulting in deformation of the material in the cutting; therefore, in the processing of metal materials should be used to eliminate internal stresses such as tempering and vibration aging, so that the internal stresses of the material and the structure of the material as much as possible tend to be stabilized to reduce the machining of the Deformation. Nylon material in the casting production, often appear or large or small pores or holes. When the mold temperature is too high, nylon products are prone to shrinkage; Conversely, due to the instantaneous separation of the polymer in the monomer is not completely dissolved, and easy to cause microporous. In addition, nylon reactants will be more or less mixed with volatile or decomposable material, casting will produce volatile products, the formation of products in the bubble or hole, these holes in a large extent caused by the instability of the nylon material, - once the structure is changed, the internal stresses to re-balance, the material is easy to produce deformation.

Nylon material in precision machining is also a commonly used materials, often used to process small precision fixtures, due to the hardness, toughness and processing characteristics of nylon material, in precision parts processing has played an irreplaceable role, when Lee and the company processed a lot of precision fixtures made of this material, encountered in the thin-walled nylon processing parts, there will be easy to deform the situation, the precision is more difficult to control. Today we will talk about cnc nylon parts processing skills. First of all, nylon machining less than 30mm small holes, due to the small holes in the space is narrow, heat dissipation difficulties, the operation of the lathe needs to reduce the lathe speed to 300 rpm or less, with the cutting fluid to be cooled; slow, even speed into the drilling, chip removal in a timely manner; through the hole, to the bottom of the hole, the drilling bit is going to penetrate the need to be more careful, reduce the speed of the drilling, cutting fluid or coolant, it is necessary to uniformly sprayed to the hole position. Secondly, nylon machining processing greater than 30mm punched holes, first of all, to sharpen the drill bit, easy to process, reduce the scrap rate; will reduce the lathe speed to 180 rpm or less, greater than 55mm holes, you can reduce the lathe speed to 60 rpm or so; slow, even speed into the drilling, timely chip removal, spraying sufficient cutting fluid; drilling out of the holes, be careful, reduce the speed of the drilling. Then, nylon machining for small hole reaming processing, the lathe speed should be lower than 60 rpm; uniform speed, low speed into the drill, the operator must hold the tailstock handle, to prevent the drill from being quickly brought into the hole by the lathe, resulting in the collapse of the product; cutting fluid spray evenly. In nylon thin-walled precision machining parts, should be taken vigorously clamping the initial machining lightly clamping finishing processing sequence to ensure that the clamping force does not affect the precision parts size processing accuracy. Nylon materials and metal materials are different in nature, with low density, easy to deform and easy to process the characteristics. Then in the clamping process will be more likely due to the clamping and deformation of precision parts after the completion of processing elastic recovery so that its size and shape changes, the greater the isthmus holding force, the greater the deformation after the completion of processing. Usually in the workpiece clamping, clamping force will make the workpiece deformation, unloading the workpiece elastic deformation automatically recovered, resulting in the workpiece free of force under the conditions of size and processing size is not the same. If the clamping force is too large, a long time after the clamping of precision mechanical parts will produce plastic deformation, after processing the clamped part of the parts of the machining size does not match. Conversely, it will lead to the clamping is not tight, precision parts processing vibration, affecting the quality of precision parts processing dimensions. Nylon parts processing, should avoid the tool itself to bring too much squeeze pressure, the tool cutting process in the continuous movement to the inside of the material, in addition to the tool on the side of the material cutting there is a direct pressure to advance, if the propulsion pressure is too large, not only will affect the clamping stability of the precision mechanical parts, will also directly cause deformation of the precision parts, resulting in workpiece Elastic deformation recovery after the size deviation is too large. Stiffness of the stronger tool relative to the stiffness of the weaker tool's own poor elasticity is more likely to produce propulsive force on the processed workpiece, resulting in the deformation of the workpiece so, the use of relatively weak stiffness of the alloy machining accuracy is better. Finally, nylon round machining, processing tool selection of white steel tools, should not choose alloy tools, tools should be kept sharp; lathe speed of not less than 200 rpm; appropriate feed speed to improve machining accuracy and surface finish. The sharpness of the knife edge on the precision machining accuracy has a great impact, the sharper the edge of the tool, the smaller the cutting resistance, the smaller the propulsion of the material, the smaller the deformation of the workpiece, the smaller the rebound phenomenon the better able to ensure that the precision mechanical parts processed dimensional accuracy, so the use of alloy knives for processing of nylon materials, three knives better than the quadrangular knife.

Antistatic polyetherketimide (PEI) sheet is a high-performance engineering plastic sheet with many properties such as high-temperature resistance, chemical stability, and electrical properties. In terms of its elasticity, PEI sheet is often thought of as a relatively hard material, but it does have a degree of flexibility. The elasticity of PEI sheet stems from its molecular structure and material properties. While PEI sheet may not be as hard as some other plastic materials such as polycarbonate (PC) or polypropylene (PP), it is still elastic enough to withstand a certain amount of stress and deformation without rupturing or deforming excessively. The elasticity of PEI sheet is primarily in its response to stretching and bending. When subjected to an external force, PEI sheet can deform elastically within a certain range and return to its original shape after the force is removed. This elasticity allows PEI sheet to perform better in applications where it is subjected to shock or vibration, as it absorbs energy and mitigates the effects of shock or vibration. In addition, the elasticity of PEI sheet makes it easier to process and mold, as it can be adapted to the shape of the molding die to some extent without cracking or damage. It is important to note that the elasticity of PEI sheet is closely related to its thickness, temperature, and the type and strength of the forces applied. Thicker PEI sheets typically have higher elasticity than thinner sheets, and high temperatures may affect their elastic properties. Therefore, when designing and engineering with PEI sheet, these factors need to be taken into account and the appropriate material thickness and operating conditions need to be selected to ensure that its performance and reliability meet the requirements of the application.

In hydraulic machinery, air pumps, and vibration-damping machinery, all moving axes, whether reciprocating or rotating, require some form of guidance to avoid metal-to-metal contact that can cause wear and tear on the equipment. The selection of the correct open rings is particularly important in hydraulic systems, as they isolate the load by pressurizing the sealing box, and in the choice of materials, also taking into account the conditions of use, in the temperature range from -35 ° C to 250 ° C. Not only that, but also excellent resistance to hydrolysis, resistance to steam, and resistance to ultraviolet rays, so that the choice is made of PTFE polytetrafluoroethylene, PEEK polyetheretherketone, PI. Torlon-PAI, CNC finishing and injection molding are available. Wear Mechanisms for Split Rings, Guide Rings, and Support Rings Wear resistance of the support rings in these sealing systems is the key to increasing the overall service life of the components. Wear of seals is mainly categorized into abrasive wear, abrasive wear and lubrication wear. Factors such as friction, pressure, temperature and media also have an impact on the wear resistance of the sealing system. Material selection and optimization Support ring according to the shape is also divided into O-ring and open ring, O-ring will fail due to extrusion into the hardware gap, resulting in a bite effect, is the rapid degradation of seals caused by premature failure. And then such a situation, the selection of suitable materials is particularly important, such as PEEK, PTFE, PAI, PI, etc., different materials have different performance and different prices, through different working conditions to choose the right combination of materials in order to get the maximum economic benefits. Application prospects and outlook Improving the wear resistance of support rings in sealing systems in hydraulic machinery is an area of continuous development and innovation. With the continuous advancement of materials disciplines and lubrication technology, we can expect more innovative materials to be developed to further doctor the performance of support rings, guide rings, open rings, piston rings, and sealing rings in seals for hydraulic machinery and oil pumps.

PEEK rods on the market diameter model range is generally between 3-260mm, normal 1m/3m long, PEEK rods are made of PEEK raw material particles extruded through the extrusion equipment extrusion molding semi-finished profiles, PEEK rods are widely used in small batches of large sizes or injection molding and other processes can not meet the requirements of the product machining. PEEK rods are mainly available in five grades and models: pure PEEK rods, PEEK carbon fiber reinforced (+30% CF) rods, PEEK glass fiber reinforced (+30% GF) rods, PEEK bearing grade (+10% PTFE +10% graphite +10%) rods, PEEK anti-static rods. PEEK is a high-temperature-resistant thermoplastic with high glass transition temperature (143°C) and melting point (334°C), and loaded thermal deformation temperature up to 316°C (30% glass fiber or carbon fiber reinforced grades). In different application scenarios, materials can be selected or special customized as required. Pure PEEK rods have more complete market specifications due to the range of applications, cheaper prices and larger market capacity, while other grades of PEEK rods need to look at each company's own specifications, with fewer options. PEEK-1000 (Brownish Gray): PEEK-1000 is manufactured from pure polyether ether ketone resin and has the best toughness and impact resistance of any PEEK grade. PEEK-1000 can be sterilized using the most convenient sterilization methods (steam, dry heat, ethanol, and Y-rays), and the raw material composition used to manufacture PEEK-1000 meets European Union and U.S. FDA regulations for food safety, making it suitable for very common applications in the medical, pharmaceutical, and food processing industries. PEEK-HPV (black): The addition of PTFE, graphite and carbon fiber makes PEEK-HPV a bearing grade plastic. Its superior frictional properties (low coefficient of friction, wear resistance, high peak pressure limit) make this grade ideal for friction applications. PEEK-GF30 (brownish gray): A reinforced grade filled with 30% glass fibers, this material has better stiffness and creep resistance than PEEK-1000, as well as better dimensional stability, making it ideal for structural parts. It is ideal for structural parts. It can withstand fixed loads at high temperatures for extended periods of time. If PEEK-GF30 is used as a sliding part, its suitability should be carefully tested because glass fibers scratch the mating surface. PEEK-CA30 (black): Reinforced with 30% carbon fiber filler, this material has better mechanical properties (higher modulus of elasticity, mechanical strength, and creep) and is more wear-resistant than PEEK-GF30, and the carbon-fiber-reinforced plastic is 3.5 times more thermally conductive than unreinforced PEEK - dissipating heat from the bearing surfaces more quickly. PEEK polyether ether ketone material selection criteria PEEK can also be called polyether ether ketone, as a high-performance semi-crystalline plastics, such plastics have excellent chemical resistance, mechanical strength, dimensional stability and a series of good performance, according to the performance is divided into a variety of series of materials, the most common classification of PEEK materials are PEEK pure material, glass fiber or carbon fiber modification. #peek material #PEEK pure material is PEEK is the most widely used PEEK plastic, in addition to the excellent properties mentioned earlier, PEEK pure material also shows particularly high toughness in the PEEK series. We can see that the elongation at break is 15%, and although PEEK Pure is tough, the material has a modulus of elasticity of only 4,200mpa, the lowest in the family of plastics. This relatively low modulus means that PEEK pure is 'softer' and less abrasion resistant than other PEEK modifiers. Therefore, if you are using PEEK pure in frictional working conditions, be aware of material loss due to wear of the material. 01 Chemical resistance PEEK pure material in chemical resistance, PEEK pure material is the best chemical resistance in the PEEK family, it can be said that only 98% of concentrated sulfuric acid can dissolve PEEK pure material, general chemicals, simply can not play any role in it, the resistance of different chemicals is also different, but also showed resistance to steam hydrolysis, is the production of high temperature disinfection of instruments need to be made of the ideal material. 02 Lightweight and strong The light weight of PEEK pure material is also worth mentioning, the density of the material is only 1.31g/cm3. In the aerospace industry, the plastic has been used for structural components due to its light weight and good mechanical strength. 03 Good insulation, excellent electronic properties Another excellent property of PEEK pure material is insulation, which is the core key to oil logging technology. For some industries where the working conditions are both high temperature and high pressure, such as the oil and gas industry, it is able to maintain insulation and high mechanical strength in extreme environments. In addition, PEEK plastic also shows excellent electronic properties, it has a very stable dielectric constant and low dissipation factor, which makes the material can be used in telecommunications technology. PEEK 30% Glass Fiber Filled PEEK GF30 is a glass fiber filled PEEK pure plastic. Due to the glass fibers, the biggest difference between PEEK GF30 and PEEK pure is the modulus. PEEK GF30 has a modulus value of 6,300 mpa, the highest in the PEEK family, and the high modulus value means that PEEK GF30 has higher stiffness and wear resistance compared to PEEK pure. Correspondingly higher stiffness makes the plastic more brittle. 01 Excellent Wear Resistance PEEK GF30 material has an elongation at break of 5%, a particularly smooth surface and a low surface coefficient, making the material suitable for applications requiring rigid friction rather than impact. 02 Low deformation temperature More importantly, PEEK GF30 due to the addition of glass fibers, in the same, high temperature and high pressure deformation is lower than the PEEK pure material, when the temperature exceeds the glass transition temperature of the PEEK more than 150 ℃, the material will be glassy, in this case, recrystallization occurs, it will be correspondingly, reduce the mechanical strength of the PEEK material, but for PEEK GF30 due to the presence of glass fibers, the recrystallization rate will be reduced, so that if the PEEK pure material and PEEK GF30 in the same high temperature and high pressure working conditions, the deformation temperature of PEEK GF30 will be lower. PEEK 30% carbon fiber filled PEEK CA30 is a 30% carbon fiber filled plastic based on PEEK pure material, compared to PEEK pure material, the carbon fiber increases the modulus while maintaining maximum toughness of the material.The modulus of elasticity of PEEK CA30 is 6000mpa and the elongation at break is 10%. So PEEK CA30 is a material that maintains very high stiffness and relatively high toughness. In addition, carbon fiber modified PEEK exhibits excellent wear resistance and very good friction properties : PEEK CA30 has better wear resistance compared to PEEK GF30. In addition, carbon fibers conduct heat more efficiently. PEEK CA30 is therefore suitable for sliding applications.

Anti-static PEEK sheet and ordinary PEEK sheet is based on polyetheretherketone (Polyetheretherketone, referred to as PEEK) material made of sheet, there are some differences in performance and characteristics. The following is the difference between anti-static PEEK sheet and ordinary PEEK sheet: 1. Anti-static properties: anti-static PEEK sheet has better anti-static properties, by adding conductive agents in the material, can effectively prevent static electricity accumulation and electrostatic discharge phenomenon. And ordinary PEEK board does not have anti-static properties. 2. Surface resistivity: antistatic PEEK board surface resistivity is low, usually between 10^3-10^9 Ω, can be in the anti-static range. The surface resistivity of ordinary PEEK board is higher, usually between 10^13-10^15 Ω, which cannot effectively prevent static buildup. 3. Polymer structure: antistatic PEEK board in the addition of conductive agents can change the polymer structure, so that the formation of conductive network structure, in the electronic level to provide continuous conductive effect. While ordinary PEEK boards have no conductive agent added, the polymer structure is pure. 4. Fields of use: Because the anti-static PEEK board has anti-static characteristics, can avoid static electricity on electronic components and sensitive equipment damage, so commonly used in electronics, semiconductors, medical equipment, aerospace and other areas that require anti-static protection. Ordinary PEEK board is commonly used in machinery, automotive, aviation and other fields, the anti-static requirements are not high occasions. 5. Other performance differences: anti-static PEEK board and ordinary PEEK board in other properties are basically consistent, including high temperature resistance, corrosion resistance, mechanical properties and wear resistance. They both have excellent chemical resistance, rigidity and heat resistance, and can adapt to the requirements of the harsh working environment. It should be noted that the conductivity of anti-static PEEK sheet will gradually decrease over time. In addition, in some special application scenarios, anti-static PEEK board may require further grounding, static dissipation and other processing to ensure effective anti-static effect. In summary, anti-static PEEK boards are mainly used to achieve anti-static function by adding conductive agents, and are suitable for areas with high requirements for anti-static performance, while ordinary PEEK boards do not have anti-static properties and are suitable for general mechanical and engineering applications. The choice of which type of PEEK board should be based on specific application requirements and environmental conditions to decide.
