Injection Molded & Painted Automotive Side Mirror Housing

The four circular mounting holes on the back and the irregular hollow structure at the center form the key features of this component as the core load-bearing base for the vehicle's side vision system. Its asymmetrical triangular rounded contour is designed to strictly conform to the body waistline, while edge clearance notches adapt to door sheet metal or base brackets, ensuring that gap and flushness meet整车 exterior aesthetic standards after assembly.

The part surface features a high-gloss black coating, which imposes stringent requirements on substrate flatness. The manufacturing process strictly controls injection molding shrinkage to prevent sink marks, flow lines, or weld lines from appearing on Class A surfaces. For such thin-walled shells with complex curves, gate location design and cooling system layout directly determine dimensional stability and surface finish, which are critical for ensuring paint adhesion and visual quality.

Leveraging our in-house closed-loop production capabilities for injection molding and painting, we offer one-stop delivery from raw material modification and precision injection molding to primer, basecoat, and clear coat processing. Equipped with Haitian and LK high-precision injection molding machines, along with BYK colorimeters and CMM inspection equipment, we strictly control color batch consistency (Delta E value) and dimensional tolerances of key mounting positions, meeting automotive-grade acceptance standards under the IATF16949 system.
