The quality of injection molding products depends greatly on the control of the injection molding process. Some process parameters, such as temperature and pressure, affect the state of the injection molding process and thus affect the quality of the product. The diagnosis of the injection molding process is particularly important. At present, various diagnostic techniques for injection molding processes have been developed. For example, thermal analysis, thermogravimetric analysis, etc., are used to monitor the quality of injection products by measuring parameters such as heat flow, viscoelasticity, and scale of the melt.
