Transparent plastic injection molding is a common manufacturing process, widely used in the production of various plastic products. However, in the manufacturing process, due to various reasons, there may be some defects that affect the quality of the product.(1) Silver grain: by the mold filling an

During the injection molding process, there is a certain gap between the plastic and the plastic in the unloading stage, and it is brought into the barrel after the screw shear. During the screw shear process, the material will undergo physical changes, from the glass state to the high elastic state, from the high elastic state to the viscous flow state, the change process may only be a few seconds - tens of seconds, in such a short time to transform a complex process. Injection defects also occur;

Transparent plastics due to high light transmittance, it is necessary to require strict surface quality requirements of plastic products, can not have any markings, pores, white. Fog halo, black spots, discoloration, poor luster and other defects, so in the entire injection process to raw materials,

In injection molding production, injection molding defects are a problem that every manufacturer may face. These defects may affect the quality of the product and even cause product failure. In order to solve this problem, we need to deeply understand the causes of injection defects and take appropr
