PEEK, which an aromatic crystalline thermoplastic polymer material, the melting point of 334 ℃, the following is a charming feature: short-term heat resistance by adding glass fiber or carbon acid after heat distortion temperature up to above 300 ℃; long-term heat resistance index for the UL 250 ℃; toughness, resistance, However, up to UL-0 level, […]
Plastic molding is a cyclic process, with each cycle including: dosing – molten plastics – Injection pressure – Filling the cooling – Kai-mode pickup. Remove the plastic parts and then re-closed mode, the next cycle. 1.2 The structure of the injection molding machinePlastics injection molding machine according to two ways of piston and screw injection molding machine

Bubbles issues are also know as vacuum bubbles, in which gases are very thin. In general, if the bubbles happen at the moment when you open the moulds, the bubble is a matter of gas interference. Vacuum bubbles are formed, because the plastics fillings are insufficient or pressure is low. Solutions(1) Increase injection volumes; adjust
