In the specific production process of injection molded parts, the lack of professionalism of the production team is an important problem, which will directly affect the quality of injection molded parts. Non professional plastic injection molding processing and customization manufacturers will cause the injection molding parts to have dents and shrinkage marks. Insufficient cooling time and high material temperature may cause such defects, which will significantly reduce the product compliance rate. At the same time, due to the lack of professional quality of the injection molding parts production team, to a certain extent, it will not be able to adjust the appropriate process in the production process, and the lack of professional production personnel will make it appear powerless in the production process, and can not be solved in time and effectively in the face of changes in environmental temperature and humidity or raw material batch number. The lack of professional knowledge and skills makes the production personnel lack executive power in the production process, which will inevitably lead to loopholes in the production process. In the production of plastic injection molding parts, it is very important to rationalize the structural design of the parts. In the current production of injection molded parts, the unreasonable design of part structure has seriously affected the quality of injection molded parts. Due to the unreasonable structure design of parts, problems will occur in production. Carelessness and negligence of part structure designers are also the key factors leading to unscientific part structure design. Part structure designers often fail to make reasonable design thinking on the quality of injection molded parts, which leads to failure to effectively improve the quality of injection molded parts
