Abstract

The injection molding is a manufacturing technique for making parts from both thermoplastic and thermosetting plastic materials in production. Molten plastic is injected at high pressure into a mold, which is the inverse of the product's shape. From the previous data that had been taken, there are increasing rejected part. By using the classical method, it can reduce the rejected value. This study will research to provide a high level review and analysis of the governing principles to identify theoretical limits on process performance. The variations in the machining parameters, such as temperature, time, pressure, and distance greatly affect the measures of the machining performance. Therefore, proper selection of the machining parameters can result in better machining performance. After conducting an analysis for these parameters, which is the main factor of the rejected value increased one solution from the aspect machine scale already approachable and its value already at the optimum level. From the new parameter setting, which is the optimum range value, one experiment was carried out on these machines and finally it is shown that the rejected values are decreasing.
