Automotive Side Mirror Housing Injection Molding Parts

This component serves as a streamlined protective cover for the automotive exterior side mirror system. It features an irregular curved surface design with预留 installation clips and positioning holes. The contour strictly aligns with the vehicle's body waistline, while edge cutouts accommodate door sheet metal or base brackets, ensuring that gaps and flushness meet整车 appearance standards after assembly.

The part surface features a high-gloss black coating, demanding exceptional substrate flatness. During injection molding, shrinkage rates are strictly controlled 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.

Leveraging our in-house closed-loop capabilities for injection molding and painting, we provide one-stop delivery from material modification and precision molding to primer, basecoat, and clear coat application. Equipped with spectrophotometers and CMM (Coordinate Measuring Machines), we strictly control color batch consistency (Delta E values) and dimensional tolerances at key mounting points, meeting IATF16949 requirements for automotive-grade appearance and functional acceptance.
