Abstract

Abstract: Taking the design of TV power button as an example, the formation of air traps defect was analyzed with the help of Moldflow software in simulating the region of air traps generated in the flow process. The runner system of the injection mould was improved so as to eliminate the air traps defect in the surface of the button. As a result, the molding was improved and the mass production of the injection was enhanced.

Key words: air trap, weld line, flow analysis, injection molding, Moldflow
