Transparent plastic, because of the high light transmission rate, necessarily requires strict surface quality requirements for plastic products, which cannot have any mottling, porosity, whitening. Fog halo, black spots, discoloration, poor gloss and other defects, and therefore in the entire injection molding process of raw materials, equipment. Therefore, the whole process of injection molding should pay great attention to raw materials, equipment, molds, and even product design, and put forward strict and even special requirements.
Secondly, because of the high melting point and poor fluidity of transparent plastic, in order to ensure the surface quality of the product, it is often necessary to make fine adjustments in the machine temperature, injection pressure, injection speed and other process parameters, so that the injection plastic can be filled with mold, and will not produce internal stress and cause product deformation and cracking. Therefore, from the preparation of raw materials, equipment and mold requirements, injection molding process and product raw material handling several aspects are to be strictly operated.
