Automotive Electrical Injection Molded Housing Assembly

Orange and black structural components featuring reinforcing ribs, snap-fits, and precision mounting holes form the external protective system for Battery Distribution Units (BDU) or electronic control modules in new energy vehicles. These parts provide physical support and electrical insulation for internal high-voltage components through integrated molding design. Complex surface textures and interface features secure wire harness routing and relieve stress, ensuring connection reliability under vehicle vibration conditions.

For such large, thin-walled injection molded parts, the core of processing lies in controlling dimensional consistency across multi-cavity molds and maintaining flatness on key mating surfaces to prevent assembly interference or sealing failures caused by shrinkage deformation. Materials typically include engineering plastics with high heat resistance and flame retardancy (such as PBT, PA66) or glass-fiber reinforced thermosetting materials (DMC/BMC) to withstand severe thermal shock. For terminal seat areas involving metal inserts, strict control over insert positioning accuracy during injection molding is required to eliminate quality risks such as flash overflow or insufficient bonding strength.

With over 20 years of experience in precision mold development, Jianda Electric is equipped with high-tonnage horizontal injection molding machines from brands like Haitian and Engel, as well as specialized DMC thermosetting injection equipment. We offer one-stop manufacturing services ranging from mold flow channel optimization to final product assembly. Our production site adheres to the IATF16949 quality management system, utilizing Zeiss CMMs and industrial CT scanning to monitor key mounting holes, internal void defects, and material RoHS compliance throughout the process. This ensures delivered products meet the supply chain standards of mainstream European and American automakers and electrical giants.
