Optimization of Injection Molding Process Parameters for Carabineer Lock Using the Taguchi Method

The injection molding process is critical to manufacturing various plastic products, including carabineer locks. A simulation-based optimization approach is conducted in this study using the Taguchi method to achieve optimal process parameters for carabineer lock production. The Taguchi method identified the key factors that affect the process output, which can be used to optimize the process and minimize defects. Main effect analysis and analysis of variance are also included in this study. The results revealed that shrinkage is significantly affected by packing pressure (E) and melt temperature (B). However, the most influential factors for warpage are packing pressure (E), melt temperature (B) and cooling time (A). The verification test showed that the optimized factor and level reduced the shrinkage and warpage in the injection molding. The results from the simulation-based optimization are expected to guide the selection of appropriate parameter settings for the injection molding process, leading to improved product quality and reduced manufacturing costs.
