Design and Flow Analysis of Injection Mold for Car Indoor Bezel Using Simulation Software

Injection molding is a manufacturing process used to produce a wide range of plastic parts and products. A complex shape and size, over 30% of plastic component is fabricated by injection molding process. It involves injecting molten plastic material into a mold cavity, allowing it to cool and solidify, and then ejecting the finished product from the mold. Injection molding is a complex process, and variations in different parameters can lead to various defects in the final molded product. The optimization of these defects depends on several parameters injection pressure, injection speed, gate location, melt temperature, mold wall temperature, etc. The location and design of the gate, which is the entry point for the molten plastic into the mold, can impact the flow pattern and potential gate-related defects. In this paper, we performed a flow analysis at different gate locations using SOLIDWORKS Software. In this firstly we process reverse engineering on car bezel to generate surface model and then design an injection mold with the core and cavity for car indoor bezel at two different gate locations. After analysis, the result shows that at mid-position of the gate location gives a better result for the final product.
