Abstract: Compared with the traditional injection molding technology, rapid heat cycling molding (RHCM) can remarkably improve the replication capability of polymer melt to cavity, eliminate some potential molding defects and increase rigidity and strength of the part. The process parameters optimization of a front shell of LCD television manufactured by RHCM technology was investigated by coupling with orthogonal experiment, CA analysis and data processing technology. The most important process parameters influencing each main quality index were determined based on analysis of variance (ANOVA) method firstly. Then the more optimum parameter set were found based on range analysis and synthetical balance analysis technology. The case results showed that the method was feasible and effective on processing quality optimization of high-gloss surface plastic part.

Key words: rapid heat cycling molding technology, orthogonal experiment, computer aided engineering analysis, data processing, synthetical balance analysis
