INFLUENCE OF POLYMER RHEOLOGY ON WELD LINE OF INJECTION-MOLDED PRODUCTS

Liu Bin,Xie Yi(The Key Laboratory of Polymer Processing Engineering of Ministry of Education,National Engineering Research Center of Novel Equipment for Polymer Processing,South China University of Technology,Guangzhou 510640,China)  
The classification and characteristics of weld line of injection-molded products are introduced.The effects of polymer rheology on appearance and property of weld line are analyzed.With the emphasis on improving weld line's influence on injection-molded products' appearance and property,the methods to adjust injection processing parameters which change rheology of polymer are discussed.And the methods that can reduce the damage,which is caused by weld line,are also put forward.
