Injection molding is an important process in plastic manufacturing, especially for mini tray production that requires stability and severe accuracy. Temperature and injection time affect product quality, including material distribution and possible defects. This study aims to analyze the effect of these two parameters on the final weight of the product and determine optimal arrangements to achieve consistent quality. This study uses an experimental method with independent variables in the form of temperature and injection time, as well as the dependent variable in the form of product weight. Data is collected through testing with KT-105 injection molding machine and analyzed using Minitab 19 software to test the relationship between variables statistically. The results showed that the temperature and time of injection had a significant effect on the weight of the mini tray. Anova analysis proves a strong relationship between these two parameters, with a p-value value <0.05
