PEEK injection molding
PEEK is widely regarded as one of the best performing thermoplastic materials on the market. PEEK is a semi crystalline thermoplastic with excellent wear resistance, chemical resistance, and hydrolysis resistance. In many cases, additives are not required. PEEK injection molded products have been widely used in fields such as aerospace, automotive industry, electronics and electrical, and medical machinery.

The temperature of PEEK injection molding is about 320~390 degrees; Drying temperature 160-185, 5H-8H; The temperature of the injection mold is 140~180. The molding temperature of this material is too high, which can cause serious damage to the screw. When setting the screw speed, the speed should not be too fast. After the molding is completed, the screw should be quickly cleaned with PE wax, and the PEEK material should not stay on the screw, otherwise the damage to the raw materials for secondary heating of the internal structure will be more severe. When choosing PEEK material for injection molding screws, it is essential to use high-quality alloy screws.
