Automotive Lighting Injection Mold Solutions | Geqin Auto Parts

Our automotive lighting injection molds are precision-engineered to produce high-quality optical components that meet stringent industry standards. These molds are constructed from premium tool steels (NAK80, S136) with optical-grade polishing (Ra<0.025μm) on critical surfaces. The designs incorporate advanced temperature control systems with multiple cooling zones (±0.5°C uniformity) to prevent warpage in large lens components. We implement vacuum-assisted venting systems that eliminate gas traps in complex optical geometries. The molds feature durable coatings (CrN, TiAlN) on cores and cavities to extend tool life when processing abrasive optical materials like PC and PMMA. Our automotive lighting molds include precision alignment systems (DME standard) that maintain perfect shut-off over 500,000+ cycles. We offer both conventional and hot runner configurations, with hot runner systems optimized for minimal material waste in high-volume production. The molds are designed to accommodate subsequent secondary operations like coating, metallization, and assembly. Our quality assurance includes comprehensive testing of first articles using coordinate measuring machines and optical comparators.
