PEEK ball applications
1. Aerospace field: PEEK balls are widely used in the manufacture of aerospace parts, such as
seals and bearings for aircraft engines, due to their excellent high temperature resistance, high strength and light weight.
2. Automotive industry: in the automotive industry, PEEK balls can be used to manufacture high-performance engine parts, transmission system parts and brake system parts, etc., to improve the performance and reliability of automobiles.
3. Electronic and electrical fields: PEEK balls have good insulating properties, and high temperature resistance, corrosion resistance, suitable for the manufacture of electronic and electrical field connectors, insulators and other parts.
4. Medical field: PEEK has good biocompatibility and corrosion resistance, PEEK balls can be used in the manufacture of medical equipment, artificial joints, dental implants, etc..
5. Chemical field: PEEK balls can be used in the chemical field to manufacture valves, pump seals, etc., and can withstand the corrosion of various chemical substances.
Third, the injection molding process of PEEK ball
1. Raw material preparation: select high-quality PEEK resin particles, to ensure that its purity and performance meet the requirements. 2. drying process: due to the PEEK resin particles, it can be used in the injection molding process.
2. Drying treatment: due to the PEEK has a low water absorption, but in the injection molding before the need for drying treatment to remove moisture, to prevent defects such as bubbles in the injection molding process.
3. Injection molding equipment selection: selection of equipment suitable for PEEK injection molding, including injection molding machines, molds and so on. The injection molding machine should have high injection pressure and temperature control precision. 4.
4. Process parameter setting: according to the characteristics of PEEK and product requirements, set the appropriate injection molding process parameters, such as injection temperature, pressure, speed, time, etc.. Generally speaking, the injection temperature of PEEK is relatively high, usually between 350℃-400℃. 5.
5. Mold design: Mold design should take into account the shrinkage, fluidity and other characteristics of PEEK, to ensure the dimensional accuracy and surface quality of the product. The mold should be made of high quality steel, and appropriate heat treatment and surface treatment.
6. Injection molding process control: In the injection molding process, the process parameters should be strictly controlled to ensure stable product quality. At the same time, pay attention to observe the appearance and size of the product and adjust the process parameters in time.
7. Post-treatment: PEEK balls after injection molding may need some post-treatment, such as annealing, deburring, etc., in order to improve the performance and appearance quality of the product.
Summarize
In addition to PEEK balls, high-strength Vespel (
PI) balls, high-performance Torlon (
PAI) balls, respectively, suitable for different working conditions assembled in the bearing ball, widely used in semiconductor, food and beverage canning industry, automotive industry, compared with the traditional metal balls, rubber balls, has incomparable advantages.
