Abstract
Injection molding is a process of making products or components from thermoplastic materials that requires careful control. There are several parameters that affect the quality of the finished product, including injection time and backpressure. This study aims to determine the effect of injection time and backpressure on product defects of water reservoir from GPPS material using Haitian 470 Ton machine. In this study, injection time parameters were tested with times of 3.5, 4 and 4.5 seconds and backpressure of 8 kgf/cm² and 10 kgf/cm². 15 samples were collected for each parameter variation during the tests. n the first test with a backpressure of 8 kgf/cm² with an injection time of 3.5-4.5 seconds no product defects were found. However, in the second test with a backpressure of 10 kgf/cm² with injection times of 4 and 4.5 seconds, visual blackdot defects appeared.
