Abstract

This study emphasizes on warpage of support structure of computer hard disk for optimum processing by precision injection molding. Firstly, the authors use Moldflow software to analyze the runner's balance on multi-cavities for the support structure of computer hard disk. Then this study accords to these data to manufacture the real mold. This study uses different processing parameters (injection speed, injection pressure, mold temperature, packing time and melt temperature) to fabricate support structure of computer hard disk using precision injection molding. The authors use Taguchi method to find out which factor is more important for warpage of support structure of computer hard disk. The results show that the most important factor for warpage of support structure is followed by packing time, injection speed, melt temperature, packing time and the last one is the injection pressure.
