Automotive Sensor Insert Molding Bracket

The black engineering plastic base features a long strip shape with circular through-holes at both ends for bolt locking and positioning. The left side integrates a rectangular connector structure with pre-embedded metal PINs serving as electrical connection carriers.

These thin-walled, long-span brackets have strict requirements for injection molding flatness and PIN position accuracy. Warpage deformation must be strictly controlled to ensure the coaxiality of the mounting holes at both ends, preventing assembly-induced internal stress. The embedding precision of the PINs and the interface profile dimensions must facilitate smooth mating with wire harness plugs, while the structural strength must withstand vibration and shock during vehicle operation.

Leveraging vertical and horizontal injection molding machines, we achieve high-quality insert molding. We develop high-gloss, precision molds using slow wire cutting and mirror EDM technologies to minimize weld line defects. Throughout the production process, we utilize 2D video measuring instruments and CCD automatic inspection equipment to monitor PIN position, mounting hole locations, interface mating dimensions, and appearance defects. This ensures our products meet the dimensional stability and reliability standards required for automotive-grade components.
