At present, in the production of mobile phones, the production process of the mobile phone case is many and complicated, and a mobile phone case with a better quality can improve the overall appearance quality and the tactile feeling of the mobile phone. The mobile phone case is made by injection molding, machining, etc., of which injection molding is the first process and an important process, which is related to the internal quality of the mobile phone case.

The casing injection mold can perform injection molding of multiple products at the same time. In the injection molding project, the lower mold can be heated and kept warm to avoid the unsatisfactory injection effect caused by the cooling of the injection material. When the material is filled with the injection mold, it can gradually cool down slowly , injection molding effect is good.
