Automotive Side Mirror Lens Injection Molded Parts

This component features a standard triangular geometry with rounded corners and a uniform light blue coating. As a core optical element of the vehicle's exterior side mirror system, it is designed to provide clear rear-side visibility. The edges are finely chamfered to ensure a precise gap fit with the protective housing, preventing looseness or noise during driving while meeting the streamlined aesthetic requirements of the vehicle's exterior.

The mirror substrate typically consists of high-flatness thermoplastic or glass. The manufacturing process adheres to strict tolerances for flatness and radius of curvature to prevent image distortion and ensure driving safety. For such irregular thin-walled structures, controlling shrinkage rates and eliminating internal stress during injection molding are critical challenges. We optimize mold cooling systems and holding pressure parameters to eliminate surface defects like sink marks and flow lines, ensuring strong adhesion and durability of the reflective layer.

Leveraging our in-house closed-loop capabilities for injection molding and surface treatment, we offer one-stop delivery from raw material modification and precision molding to spraying. Our production facility is equipped with high-precision Haitian and LK injection molding machines, along with CMMs and BYK color spectrophotometers. This allows us to strictly control dimensional tolerances at key mounting points and ensure color batch consistency (Delta E value). Operating under the IATF 16949 quality management system, we are capable of handling everything from small-batch prototyping to mass production, ensuring products meet the stringent appearance and functional acceptance standards of OEMs.
