Abstract

Abstract: The warping deformation of three back-cover of keyboards made from PC, ABS, and PC/ABS were numerically simulated with Moldflow software. A orthogonal simulation experiment was designed and performed. The optimal process parameters were obtained by range analysis. For injection molding of PC, ABS, and PC/ABS, the mold temperature being 100, 40，and 50 ℃, melt temperature being 290, 260，and 240 ℃, injection time being 2.0, 1.0，and 2.5 s, pressure holding time being 25, 15，25 s, respectively. The holding pressure was 110 % the corresponding injection pressure for all three materilas.

Key words: warping deformation, polycarbonate, acrylonitrile-butadiene-styrene copolymer, thin-walled plastic part, orthogonal experiment
