The rapid development of new energy vehicles demands significant improvements in connector structures and performance standards. Wire harness connectors, crucial for linking various electrical components, face challenges due to their small size and thin-walled structure, which can lead to dimensional shrinkage and warping during injection molding. To address these issues, this study optimizes the injection molding process by fine-tuning parameters such as melt temperature, mold temperature, injection time, holding pressure/time, and cooling time. By integrating the Taguchi method with grey relational analysis, the study enhances the molding process for thin-walled composite connectors. This combined approach provides a comprehensive framework for optimizing multiple quality objectives and improving the overall performance of injection-molded composite components.
新能源汽车的快速发展要求连接器结构和性能标准有显著提升。线束连接器对于连接各种电气部件至关重要，但其尺寸小且壁薄的结构使其在注塑成型过程中面临挑战，可能导致尺寸收缩和翘曲。为解决这些问题，本研究通过微调诸如熔体温度、模具温度、注射时间、保压/保压时间和冷却时间等参数来优化注塑成型工艺。通过将田口方法与灰色关联分析相结合，该研究改进了薄壁复合连接器的成型工艺。这种组合方法为优化多个质量目标和提高注塑复合部件的整体性能提供了一个全面的框架。
