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.

We utilize high-performance steel alloys and coatings that extend tool life to 1M+ cycles for production molds. Our energy-efficient mold temperature control systems maintain precise thermal conditions with minimal power consumption. The molds incorporate automated sensor systems that monitor production parameters and detect potential quality issues in real-time. We offer complete turnkey solutions including mold design, fabrication, validation, and production process optimization. Our technical team can develop custom high-efficiency solutions for specific production volume requirements or unique part geometries. All molds are designed with maintenance accessibility in mind to minimize downtime during production runs.

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.

Complex parts can be formed perfectly, high precision

We needed an injection mold for a complex automotive dashboard part. Geqin's mold achieved perfect molding of all details, including small holes and protrusions. The dimensional tolerance is within ±0.02mm, which meets our strict requirements. The mould runs stably on our injection machine.

Low maintenance cost, stable performance

This injection mold has been used for 8 months, and we only did routine maintenance. There's no need for frequent replacement of parts, which reduces our maintenance cost. The performance remains stable, and the reject rate of products is less than 0.5%.
