Injection mold is one of the important molds in the mold industry. It can produce many plastic products with plastic molds and plastic molds. There are many requirements for injection molding processing, and what are the inspection requirements for large injection molding processing.

First, injection molding processing: raw materials must be fully dry according to the process requirements, can not have water, otherwise there will be silver on the surface after injection molding

Second, the temperature, pressure, time, etc. of the injection molding process meet the requirements of the process parameter card. The injection speed should be strictly controlled. The excessively fast injection speed will result in poor adhesion between the coating and the substrate (the injection speed of the plated parts is controlled at 15%-35%). between)

3. After the intermediate shutdown, the material should be cleaned to avoid the fragility of the injection product due to the excessive degradation of the raw material in the screw due to the long residence time.

4. In the process of injection molding, the release agent cannot be used, especially the release agent containing silicone oil, otherwise it will affect the adhesion of the coating.

5. During the injection molding process, the operator must bring cotton clean gloves to avoid contamination of the surface of the product after injection molding.

6. The surface of the parts molded by injection molding shall not be polished or polished to avoid affecting the adhesion of the coating to the substrate.

7. Internal stress control: The product is not allowed to have large internal stress, and internal stress detection should be carried out after injection molding.

8. Size control: length, assembly foot or assembly hole meets drawing and inspection requirements
