Several key elements of injection moldingInjection molding is also a separate engineering technology aimed at transforming thermoplastic raw materials into products that can be used and maintain their original performance through important process conditions of injection molding. Therefore, the form

1. Trial steps and actionsA. Before trial molding, check whether the mold has been assembled and whether the raw materials have been driedB. Before changing the mold, spray rust inhibitor on the mold during production, replace the mold and return it to its original position, and fill out a record fo

During the injection molding process, shrinkage and indentation of products are common phenomena. The main reasons for this situation are:1. Regarding the machine:(1) The nozzle hole is too large, causing the molten material to flow back and shrink. When it is too small, the resistance is high and t

The main reasons and solutions for uneven color of injection molded products are as follows:(1) Poor diffusion of colorants often leads to patterns near the gate.(2) Plastic or colorants have poor thermal stability. To stabilize the color tone of the product, it is necessary to strictly fix producti
