　　The cleaning of the barrel, screw and its accessories is to prevent raw material contamination and the presence of old materials or impurities in the concave parts of the screw and accessories, especially resins with poor thermal stability. Therefore, screw cleaning agents should be used to clean all parts before use and after shutdown to prevent impurities from sticking. When there is no screw cleaning agent, PE, PS and other resins can be used to clean the screw.

　　When the machine is temporarily shut down, in order to prevent the raw materials from staying at high temperatures for a long time and causing degradation, the temperature of the dryer and the barrel should be lowered to below 160 ℃. The temperature of the hopper should be reduced to below 100 ℃ for PC.

　　Transparent plastics require strict surface quality requirements due to their high light transmittance, and must not have any patterns, pores, or whitening. Defects such as haze, black spots, discoloration, and poor gloss affect the raw materials and equipment throughout the entire injection molding process. The design of molds and even products requires great attention and strict or even special requirements.

　　Secondly, due to the high melting point and poor flowability of transparent plastics, in order to ensure the surface quality of the product, it is often necessary to make subtle adjustments to process parameters such as high machine temperature, injection pressure, and injection speed, so that the mold can be filled during injection molding without generating internal stress that may cause product deformation and cracking. Therefore, strict operations must be carried out in terms of raw material preparation, equipment and mold requirements, injection molding process, and product raw material processing.
