Micro Plastic Part Fabrication Using Custom Made Vertical Injection Molding Machine

Abstract:

Article Preview

This study focuses on fabrication of a micro plastic part using custom made vertical injection molding machine. Electrical discharge machining (EDM) and micro mechanical machining was used to fabricate micro shape cavity on aluminum mold. The mold was embedded with Polymethyl Methacrylate (PMMA) window to observe the behavior of plastic melt flow during injection. The custom made vertical injection molding machine has capabilities to produce a micro plastic part. But, the filling behavior observation was contrast with MoldFlow analysis software. The flashing problem occurs at each molded micro part due to improper selection of injection molding parameter.
