Automotive Side Mirror Base Bracket Injection Molding Part

Serving as the internal support carrier for vehicle side-view assemblies, this component features an irregular profile tailored to fit door panel mounting positions. The central ring structure secures the mirror adjustment mechanism. Multiple snap-fits and locating pins along the edges ensure stable assembly in confined spaces, while reserved wire harness channels facilitate electrical connections.

The main body is injection molded from dark gray thermoplastic material with a matte finish. Strict control of molding shrinkage is implemented to guarantee dimensional accuracy at key mounting holes. For housings with complex ribs and thin-wall features, mold gate layout and cooling channel design are critical to determining flatness and deformation resistance, preventing excessive gaps or misalignment during subsequent assembly.

Leveraging our in-house closed-loop capabilities in injection molding and surface treatment, we provide one-stop delivery from raw material modification and precision molding to painting. Equipped with CMMs and colorimeters, we strictly control key dimensional tolerances and batch-to-batch color consistency, meeting IATF16949 standards for automotive component functional and aesthetic acceptance.
