Painted Automotive Side Mirror Housing

This component serves as the external protective shell for vehicle side mirror assemblies. Its streamlined, high-curvature surface design is engineered to cover internal mirror adjustment mechanisms and electronic components. The irregular, custom-shaped contour strictly conforms to the vehicle's body腰线 (waistline), with预留 (reserved) mounting cutouts at the bottom to clear door sheet metal or base brackets, ensuring that gaps and flushness meet overall vehicle appearance standards after assembly.

The part features a high-gloss metallic red coating, which imposes stringent requirements on substrate flatness. The manufacturing process strictly controls injection molding shrinkage rates to prevent sink marks, flow lines, or weld lines from appearing on Class A surfaces. For such thin-walled housings with complex curves, the design of mold gate locations and cooling system layouts directly determines the dimensional stability and surface finish of the final product.

Leveraging our in-house closed-loop production capabilities for injection molding and painting, we provide one-stop delivery from raw material modification and precision injection molding to primer, basecoat, and clear coat processing. Our production facility is equipped with Haitian and LK injection molding machines, along with inspection equipment such as BYK color spectrophotometers and Coordinate Measuring Machines (CMM). This allows us to strictly control color batch consistency (Delta E values) and dimensional tolerances at key mounting points, meeting automotive-grade acceptance standards under the IATF 16949 quality management system.
