塑胶注塑不良的分析以及处理措施（Plastic injection molding analysis and treatment measures） Plastic injection molding defect analysis and treatment measures of.Txt11 life of the flowers in full bloom, it was a beautiful shine, stretch, beautiful and more funding; life is beautiful, fresh and smooth, meaning long; life is beautiful music, melodious melody and harmony; life is a flowing river, rolling, rolling forward [supply chain management] bad plastic injection molding analysis and treatment measures Fisher was published in 2005-6-17 13:18:33 Injection molding part Causes of bad phenomena in injection molding * defects in dies * defects in plastic resins * unsuitable molding conditions * product design issues * excessive evaluation of molding machine performance * changes in the surrounding environment 1. ruptured albino A generalized rupture, including rupture and minor rupture of the Crazing. It can be divided into mechanical rupture and chemical stress rupture according to the causes. [1] mechanical rupture (Mechanical, Crack) The physical force acting on the plastic is greater than the inherent plastic and structural support of the plastic. In order to prevent the rupture, attention should be paid to the design of the product. When designing the materials and models used, the external forces acting on the object shall be taken into account, and a structure that reflects both the stability and the dispersion of forces will be devised. When increasing the structural support, the thickness of the product or the reinforcement of the Rib can be increased, or the Round structure can be designed to disperse the forces. [2] chemical stress rupture (ESC, Crack) Chemical stress rupture (ESC:Environmental Stress Crack) is due to the effect of chemicals, plastic expansion, thereby increasing the internal stress rupture, resulting in the total stress value is higher and the failure strength of plastics. Chemical stress rupture in the assembly process of molding products, the use of lubrica
