Two-Shot Mold Manufacturer

Precision 2k Mold Solutions for Automotive Lighting Components

As a professional two-shot mold manufacturer for automotive lighting parts, we provide high-precision tooling solutions for components that require two different materials or colors molded in a single production cycle. Two-shot molding is widely used for headlamp bezels combined with light guides, tail lamp housings paired with soft-touch seals, and lens assemblies requiring both transparent and opaque sections.

Our engineering team focuses on precise shut-off design, rotation and core-back mechanisms, and material compatibility analysis to ensure clean color separation, strong interfacial bonding, and stable dimensional accuracy across both shots. Mold flow simulation and thermal analysis are applied at the design stage to eliminate flash, warpage, and bonding defects before tooling begins.

High-grade mold steels such as 1.2343ESR, NAK80, and 718H are commonly used to guarantee long mold life and consistent surface quality under high-volume production. Our two-shot mold solutions have supported lighting programs for major automotive brands including BYD, Geely, Chery, SAIC, and GM, helping customers shorten development cycles while maintaining IATF 16949-compliant quality standards.
