PEEK injection molding-Shanghai Puju Plastic Technology Co., Ltd.

Polyetheretherketone (PEEK) is a semi-crystalline, thermoplastic aromatic polymer material, which is the main variety in the polyaryletherketone (PAEK) series of polymers. PEEK molecular chain contains a large number of benzene rings, which has excellent heat resistance, wear resistance, fatigue resistance, radiation resistance, peel resistance, creep resistance and other excellent physical and chemical comprehensive properties, and its two ether bonds and Carbonyl brings flexibility and excellent manufacturability, and is widely used in aerospace, automotive, electrical and electronic, medical and other industrial fields.

PEEK injection molding is not exactly the same as general plastic injection molding. PEEK material has a very high melting temperature and a very high viscosity. If ordinary injection molding machines and auxiliary equipment are used, injection molding of PEEK materials without experience will cause different degrees of defects in injection molding products. , Affect the performance of PEEK products, especially the mechanical properties, chemical properties, electrical properties, fatigue resistance, stress and deformation of PEEK injection products will be affected to varying degrees. PEEK injection products under special requirements must be used. When considering the work, the instability or failure of PEEK injection molded parts due to the above reasons. For PEEK precision injection molded parts, more stringent improvement requirements are placed on the entire injection molding system.
