Common Apparent Defects and Troubleshooting for Injection Moulded Products

YANG Feng-xia(Department of Chemical Engineering,Henan Vocation-Technical Teachers College,Xingxiang Henan 453003,China)  
Injection molding is one of the most important plastics moulding methods.The advantage of the method is that complicated products can be moulded one step,so it has extensive applications.But different kinds of defects often appear in the process of moulding.The factors affecting the common apparent defects of injection products are fully analyzed on the aspects of material,design of the mould,design of the product and forming techniques. The corresponding troubleshootings are gi-ven according to different affecting factors.
【Key Words】: injection product apparent defect troubleshooting
