Optimization of Warpage on Plastic Part by Using Particle Swarm Optimization (PSO) Method.

This paper proposes an optimization model of process parameters in Plastic Injection Molding (PIM) in which the quality characteristics for the plastic injection product that been study are warpage. In this study, front panel housing has been analyzed with thermoplastic material of Acrylonitrile Butadiene Styrene (ABS) used as the molded material. Design of Experiment (DOE), Response surface methodology (RSM) and Particle Swarm Optimization (PSO) method were used to analyze the optimal process parameters setting. From the results, warpage value has reduced by 35.77%. [ABSTRACT FROM AUTHOR]
