Automotive C-Pillar Cover Mold -

 Dual-Color High-Gloss PMMA/ABS with Backlit Through-Light Technology

Introduction 

This premium 2K injection mold is engineered for rear door C-pillar covers that feature a dual-color high-gloss aesthetic and integrated backlit through-light functionality. By utilizing a specialized PMMA/ABS overmolding process, the tool creates a seamless transition between the structural opaque substrate and the translucent decorative surface. A critical engineering focus of this project is the prevention of light bleed at the resin boundaries, ensuring sharp, defined illumination patterns for the vehicle's signature lighting. Side A is processed using RHCM (Rapid Heat Cycle Molding) to achieve a mirror-like finish directly from the cavity, providing superior UV resistance and weatherability without the need for secondary painting. Optimized for 1000T production, this mold ensures precise shot-to-shot consistency for complex multi-material exterior trims.
