Why choose us?

Precision Optical Component Manufacturing

Specializing in high-precision convex lenses and reflectors for automotive lighting, we utilize advanced PC/PMMA materials with 90%+ light transmittance and UV resistance. Our optical components meet strict ECE/ISO standards for beam pattern accuracy and durability in extreme conditions (-40°C to 120°C).

Integrated Mold-to-Product Solutions

Combining die casting and plastic injection mold capabilities, we produce 500+ precision molds annually for headlight housings and reflectors. Our in-house mold workshop reduces lead times by 30% while maintaining 0.01mm tolerance for complex geometries in aluminum/steel molds.

Automotive-Grade Material Expertise

With 10+ years' experience in engineering plastics, we optimize PC/PMMA formulations for headlight applications - achieving V-0 flame rating, >92% light transmission, and impact resistance up to 20J/cm² while withstanding long-term UV exposure and thermal cycling.

Full-Service Headlight Manufacturing

From optical design to final assembly, we provide complete headlight solutions including LED modules, reflector bowls, and PMMA lenses. Our vertically integrated production covers mold making, injection molding, vacuum metallization, and automated light pattern testing to ensure OEM-quality output.

Our injection mould design and production process combines engineering expertise with advanced manufacturing capabilities. The design phase utilizes 3D CAD software and mold flow analysis to optimize filling patterns, cooling efficiency, and part ejection. We produce moulds for various tonnage ranges (50-1000T) with standardized mounting patterns for easy press compatibility. The production process employs high-precision machining centers capable of holding tolerances within ±0.01mm. We implement scientific molding principles in our designs including balanced runner systems, proper gate locations, and optimized cooling channel layouts. The moulds feature durable components (guide pillars, bushings, ejector pins) manufactured from premium tool steels. Our quality control includes thorough inspection of all functional surfaces and moving components. We offer both conventional and hot runner systems, with hot runner designs optimized for minimal material waste. The mould production process includes comprehensive testing with production-grade materials to verify performance. We provide complete documentation including design drawings, material certifications, and processing parameters. Our technical team can advise on optimal mould designs for specific materials and part geometries.

Frequently Asked Questions

What types of automotive lighting components does your company specialize in?

We specialize in manufacturing high-performance automotive lighting components including precision convex lenses, reflectors, and complete headlight assemblies. Our products utilize optical-grade PC/PMMA materials with >90% light transmission, meeting ECE/ISO standards for beam pattern accuracy and durability. We offer both halogen and LED solutions with custom optical designs for various vehicle applications.
We primarily use polycarbonate (PC) and polymethyl methacrylate (PMMA) for lenses due to their exceptional optical properties. PC offers superior impact resistance (up to 20J/cm²) and heat resistance (120°C), while PMMA provides 92%+ light transmission with excellent UV stability. Both materials are 50% lighter than glass and can be molded into complex shapes for advanced lighting designs.
Our facility houses complete mold manufacturing capabilities including precision CNC machining, EDM, and wire cutting. We produce 500+ injection molds and die casting molds annually, with tolerances within 0.01mm. Specializing in automotive lighting molds, we work with H13 steel for die casting and pre-hardened steel for injection molds to ensure longevity under high-pressure production conditions.
We implement a rigorous QC process including coordinate measuring machines (CMM) for dimensional checks, spectrometers for material verification, and photometric testing for light distribution analysis. All products undergo environmental testing (-40°C to 120°C thermal cycling, UV exposure, and vibration tests) to ensure compliance with automotive industry standards.
Our reflectors feature precision parabolic surfaces with vacuum-aluminized coatings achieving >90% reflectivity. We combine injection molding and metallization processes to produce lightweight, durable reflectors with optimized light patterns. Advanced simulation software helps design reflectors for maximum luminous efficiency while meeting all regulatory requirements for beam cutoff and distribution.

Precision moulds, high production efficiency

The automotive lighting moulds we purchased from Geqin are of high precision. The molded parts have smooth surfaces and accurate dimensions, reducing post-processing work. The moulds are wear-resistant, and after 10,000+ productions, there's no obvious wear. Greatly improved our production efficiency.

Robert Chen
Durable material, long service life

The die casting moulds from Geqin are made of high-quality H13 steel. They can withstand high temperature and pressure during metal casting, and after a year of use, the mould cavity is still in good condition. The production parts have stable quality, which is very reliable.
