This paper deals with the development of accurate warpage prediction model for plastic injection molded parts using soft computing tools namely, artificial neural networks and support vector machines. For training, validating and testing of the warpage model, a number of MoldFlow (FE) analyses have been carried out using Taguchi’s orthogonal array in the design of experimental technique by cons...

Plastics is one of the world’s largest and fastest growing industries, ranked as one of the few multi-billion dollar industries. Due to the vast improvements in polymers and production processes, plastics are now amongst the world’s most widely used materials, with the world consumption of polymers surpassing steel in volume and weight. Injection molding represents approximately 32% (by weight)...

A set of edge-gated and center-gated plaques were injection molded with long carbon fiber-reinforced thermoplastic composites, and the fiber orientation was measured at different locations of the plaques. Autodesk Simulation Moldflow Insight (ASMI) software was used to simulate the injection molding of these plaques and to predict the fiber orientation, using the Anisotropic Rotary Diffusion an...

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 injec...

injection molding is the most widely used process for producing plastic parts.in this process, an important issue is to predict and optimize the warpage before manufacturing. in this paper, a simulation with moldflow software is proposed to optimize the injection molding process. the optimization process aims at minimizing the warpage of the critical injection molding part in which process para...
