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.

Foshan Geqin Auto Parts manufactures high-performance PC protective covers for various automotive applications. These covers utilize impact-resistant polycarbonate material with exceptional durability against road debris and environmental factors. The protective covers maintain optical clarity (90%+ light transmission) while providing superior protection compared to conventional materials. We offer various thickness options (1.5-6mm) to balance protection and weight requirements. The PC material features UV stabilization to prevent yellowing and maintain transparency under prolonged sun exposure. Our protective covers demonstrate excellent resistance to automotive chemicals including oils, fuels, and cleaning agents. The components are designed with precision-molded mounting features for secure attachment to vehicle structures. We can produce covers with specialized surface treatments including anti-scratch coatings (up to 3H pencil hardness) and anti-fog treatments for interior applications. The products undergo rigorous testing including stone impact resistance (SAE J400 standard) and thermal cycling evaluations. Our technical team can develop custom solutions for unique vehicle applications or special protection requirements. All protective covers meet relevant automotive standards for flammability and safety compliance.

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.

Patricia Martinez
Heat resistance meets requirements, stable at high temperatures

We use Geqin's PC material to produce parts for high-temperature equipment. It remains stable at 120℃ without deformation, which is crucial for our products. The material also has good flame retardancy, meeting safety standards. Very reliable.

Barbara Garcia
Good weather resistance, long service life outdoors

We used Geqin's PC material to make outdoor light covers. After 2 years of exposure to sunlight and rain, there's no obvious yellowing or aging. The material's weather resistance ensures the long service life of our products, reducing replacement frequency.
