Melt temperature: The melt temperature plays a major role in the melt's flow performance. Because plastic does not have a specific melting point, the so-called melting point is a temperature segment in the molten state. The structure and composition of plastic molecular chains are different. The effects are also different. Rigid molecular chains are more significantly affected by temperature, such as PC, PPS, etc., while flexible molecular chains such as PA, PP, PE and other fluids are not obvious by changing the temperature, so it should be adjusted reasonably according to different materials Temperature of the injection molded parts.

Mold temperature: some plastic materials require high mold temperature due to high crystallization temperature and slow crystallization speed, and some require higher or lower temperature due to the size and deformation control or the need for demolding, such as PC generally requires 60 In order to achieve better appearance and improve fluidity, the mold temperature sometimes needs 160 degrees or more, so the mold temperature has an inestimable effect on improving the appearance, deformation, size and rubber mold of the product.
