Suzhou Jiupeng intelligent to share with you: injection processing need to pay attention to a few details

Injection molding is an important means to produce plastic products. Many plastic products in life are processed by injection molding. Injection molding factory in the production of plastic injection parts, pay attention to the processing accuracy to meet customer requirements. In order to ensure the accuracy of injection molding products, we must pay attention to the following details.

1. Injection molding products have a certain liquidity, in the injection molding, adjust the injection pressure to control its liquidity.

2. The thermal performance and cooling speed of injection parts are different. Materials with high specific calorific value require more heat during the plasticizing process. At this time, the injection molding machine with large plasticization should be adjusted. The higher the thermal deformation temperature, the shorter the plastic cooling time and the earlier the demoulding time. Attention should be paid to avoid cooling deformation after demoulding.

3. According to the types and shapes of various plastics, it is very important to choose the right cooling rate.

4. Injection molded parts include additives that have different affinities to moisture. For hygroscopic plastics, appropriate heating methods and preheating standards should be selected in strict accordance with the requirements to avoid heat absorption during use.
