Injection Molded & Painted Automotive Side Mirror Housing

Please provide 3D models or 2D drawings to confirm surface contours and mounting dimensions. As a protective shell for vehicle exterior components, this part covers the internal mirror adjustment mechanism with a large-curvature streamlined design. Its irregular shape closely follows the vehicle's waistline, with bottom mounting cutouts designed to clear door sheet metal or base brackets, ensuring gap and flushness meet整车 appearance standards after assembly.

The part features a high-gloss black coating, which demands exceptional 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 are critical to dimensional stability and surface finish, directly impacting paint adhesion and visual quality.

Leveraging our in-house closed-loop capabilities in injection molding and painting, we offer one-stop delivery from material modification and precision molding to primer, basecoat, and clearcoat application. Our production facility is equipped with Haitian/LK injection molding machines and inspection tools such as BYK colorimeters and CMMs. This allows us to strictly control batch-to-batch color consistency (Delta E value) and key mounting dimension tolerances, meeting IATF16949 automotive-grade appearance and functional acceptance requirements.
