Electroplated Decorative Trim for Automotive Instrument Air Vents

Featuring a streamlined structure with a central circular adjustment ring and rectangular air guide frames on both sides, this component extends multiple positioning clips and mounting feet from the bottom. Commonly used in the central control dashboard area, it enhances the texture of the interior. The overall profile is smooth, with a high-gloss mirror finish on the surface, designed to unify aesthetics and functionality when paired with air vents or functional modules.

Manufacturing such thin-walled, irregularly shaped exterior parts requires strict control over mold runner balance and molding shrinkage rates. Key priorities include ensuring strong adhesion of the electroplated layer without defects such as blistering or pitting. Critical dimensional controls include the coaxiality of the central circular hole, dimensional consistency of the side frames, and the flatness of the bottom mounting positions. This ensures that gap and flushness after assembly meet OEM standards, while avoiding the risk of later deformation caused by internal stress.

Leveraging over twenty years of experience in zinc-aluminum alloy die casting and surface treatment, and holding IATF 16949 automotive quality system certification, we offer one-stop production services ranging from mold development and precision die casting to CNC post-processing and hydro-electroplating. Equipped with inspection devices such as Zeiss CMMs, we perform full inspection of key mating dimensions to ensure consistency in batch deliveries. We support non-standard customization based on 3D models or 2D drawings, meeting diverse needs from small-batch prototyping to large-scale mass production.
