The advantages of plastics1.Easy to process and manufacture (easy to shape)Even if the geometric shape of the product is quite complex, as long as it can be demolded from the mold, it is relatively easy to produce. Therefore, its efficiency is far superior to metal processing, especially injection m

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

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
