Optimization of the Injection Molding Machine and Processing Condition by Increasing Ability of Transcription and Bending Strength of Plastic Molding Test

Abstract

In the injection molding process, it is required to form the products of any shape using any type of resin within the capability of a machine. In most cases, quality has been evaluated by dimension. But in order to meet the requested product shape or resin type, molding conditions have been changed by varying the cavity shape of the mold, the component parts of the machine, etc.

In this report, both transformability and bending test were studied for crystal and non-crystal type resins. Gate position, heat related deterioration and fatigue were considered as the outer noise. The relationship between transformability and bending test was also examined.
