APPLICATION OF CAE TECHNIQUE IN ANALYSIS OF WARPAGE DEFORMATION OF THIN-WALL PLASTIC PARTS

Kang Junyuan, Yan Li Li Yonghong (Guangdong Industry Technical College, Guangzhou 510300, China) (Jingwei Branch, Foshan Plastics Group Co. Ltd., Foshan 528000, China)  
The effects of temperature field and pressure field on residual stress and deformation of injection molded parts are studied by finite element method. The step to analyze warpage deformation by CAE is given with air condition damper vane as example. The reasons such as unbalanced shrinkage, unbalanced cooling and conflicting molecular orientation which cause warpage deformation are put forward and the improving measures are given. The practice proves that high quality of plastic parts can be obtained by using these measures.
