Molded parts needing PEEK overmolding or insert molding technologies are also possible.įor precise molded PEEK parts, it is of paramount importance to ensure the PEEK polymer is optimally dried prior to molding. It is also through highly integrated control technology that we guarantee a stable process at all times resulting in components with the highest precision and exacting tolerances. Through optimal processing and mold tempering, we create the necessary semi-crystalline part that fully exploits the unique properties of PEEK. Our injection molding technology is also economical in small and medium lot sizes. We produce PEEK molded parts with the highest reliability and quality meeting various industry standards. Generally, the precision of injection molding for PEEK products can reach about 0.1mm, and the precision can be controlled at about 0.015mm according to the different wall thickness and structure of the products.Our injection molding machines and tools are specially designed for processing PEEK and other high-performance plastics. After molding, the injection screw should be cleaned quickly with PP material in time, and PEEK material should not stay in the screw. The injection pressure should be 100~130MPa and the injection speed should be 40~80. When setting the screw speed, the speed should not be too fast. It is best to find a manufacturer specializing in PEEK injection molding to avoid certain technical risks. It is different from ordinary injection molding to some extent. Peek material has a high melting temperature and a high viscosity in the melting state, which requires higher pressure and greater wear on the screw during injection. PEEK belongs to high temperature special engineering plastics, the mold temperature is 140~180, the melt temperature should be maintained at 320~390 degrees, so it is required that the heating section of the injection molding machine can provide more than 350 degrees of heating temperature. PEEK resin can also withstand up to 3000 cycles of autoclaving at 134 ° C, which makes it suitable for the manufacture of highly sterilized surgical and dental equipment requiring repeated use. In the semiconductor industry, It is commonly used to manufacture wafer bearers, electronic insulating films and various connection devices.Īs a semi-crystalline engineering plastic, PEEK is insoluble in almost all solvents except concentrated sulfuric acid, so it is commonly used to make compressor valve plates, piston rings, seals and various chemical pump bodies and valve parts. Therefore, the electronic information field has gradually become the second largest application field of PEEK resin, manufacturing pipes, valves and pumps for conveying ultra-pure water. PEEK resin is an ideal electrical insulator and can maintain good electrical insulation performance under harsh working conditions such as high temperature, high pressure and high humidity. Bearings, gaskets, seals, clutch rings and other parts manufactured by PEEK are widely used in automobile transmission, brake and air conditioning systems. In the automotive industry, PEEK resin has good friction resistance and mechanical properties, and is used as the raw material for manufacturing engine inner cover. PEEK resin was first applied in the aerospace field, replacing aluminum and other metal materials to manufacture various aircraft parts. PEEK application and Medical PEEK application parts with high mechanical strength requirements.wear resistance, antistatic electrical insulation performance is good.light weight to replace metal optical fiber components.hydrolysis resistance, high temperature and high pressure can still maintain excellent characteristics.irradiation resistance, wear resistance, corrosion resistance conditions.dimensions require precision conditions.high temperature, high frequency and high voltage performance conditions.SeaskyMedical use PEEK for both micro and large medical plastic parts manufacture. It can be manufactured and processed into various mechanical parts. Peek is a kind of special engineering plastics with excellent properties such as high temperature resistance, self-lubrication, easy machining and high mechanical strength. PEEK is together with PPS, PSU, PI, PAR and LCP as special engineering resin.
