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
