Stamping Parts die is one of the important dies in the die industry. It can produce many plastic products with plastic dies.  There are many requirements for injection molding. What are the inspection requirements for large-scale injection molding?
I. Injection Molding: The raw materials shall be fully dried according to the process requirements without moisture, otherwise there will be silver lines on the surface after injection molding
II. The temperature, pressure and time of injection molding meet the requirements of the process parameter card. The injection speed should be strictly controlled. Excessive injection speed will lead to poor adhesion between the coating and the substrate (the injection speed of electroplated parts is controlled between 15% and 35%)
Third, the material should be cleaned after the intermediate shutdown to avoid the brittleness of injection molded products caused by degradation of raw materials due to long residence time in the screw.
Four, injection molding process, can't use release agent, especially containing silicone oil release agent, otherwise it will affect the adhesion of the coating.
Five, the operator in the process of injection molding, must take cotton clean gloves, to avoid the surface of the product after injection molding is contaminated.
Six, injection molding Plastic Injection Parts surface shall not be polished and polished, so as not to affect the adhesion of coating and substrate.
Seven, internal stress control: products are not allowed to have large internal stress, internal stress testing should be carried out after injection molding.
Eight, size control: length, assembly feet or holes conform to the drawings and measuring requirements of inspection tools
