Precision Injection Molded Electrical Brackets and Fluid Fittings

Electrical insulation brackets with lateral interfaces and snap-fit features, alongside multi-way fluid connectors, are commonly used for fixing automotive electronic modules or connecting small water pump pipelines. These structures involve complex internal flow channels, mounting bosses, and thin-wall ribs, imposing high demands on mold core-pulling mechanisms and ejection balance to ensure dimensional stability that matches assembly tolerances.

For the black engineering plastic parts and white/beige heat-resistant components shown, the processing core lies in controlling the positioning accuracy of insert terminals to prevent molding flash from affecting electrical contact. Meanwhile, for fittings such as tees and elbows, strict control over inner hole roundness and sealing surface flatness is required to avoid the risk of fluid leakage. The factory is equipped with high-tonnage horizontal injection molding machines from brands like Haitian and Engel, as well as specialized DMC thermoset molding equipment, capable of handling diverse molding needs ranging from conventional thermoplastics to glass-fiber reinforced materials.

The production process relies on the IATF 16949 quality management system, combining Zeiss coordinate measuring machines (CMM) and industrial CT for full-process monitoring. Key inspections focus on critical mating dimensions, internal void defects, and material RoHS compliance. This one-stop service capability, from mold development to final assembly, is particularly suitable for automotive parts and low-voltage electrical projects with strict requirements for dimensional consistency, shrinkage-free appearance, and electrical performance. Buyers can evaluate mold amortization costs and bulk unit prices based on specific drawings.
