Injection molds need to pay attention to many problems in the production process in order to produce qualified products.

1, in the injection mold processing, due to the different shrinkage coefficients of various materials, the mold must have a reasonable shrinkage rate.

2, the injection mold should have enough rigidity during processing, otherwise it will be deformed and cause "flash" when the mold is kept under pressure.

3. The cooling (water passage) in the processing of injection molding molds is related to the size, shape, nature of plastic enterprises, pressure holding time and other factors.

4, the injection mold processing to choose a reasonable exhaust position and its control amount. Otherwise it will lead to plastic injection dissatisfaction and product "lack of material".

5, reasonable selection of injection mold processing in the injection path, so that the material evenly reached everywhere (the flow path is equal), and there is enough reserve to ensure that the plastic is supplied during the contraction process.
