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 PC and PMMA hybrid headlight lenses combine the optimal properties of both materials for superior optical performance. These hybrid lenses utilize polycarbonate for impact-resistant structural elements and PMMA for critical optical surfaces. The designs maximize light transmission (92%+) while maintaining exceptional durability against road debris. We employ advanced bonding techniques that create seamless transitions between PC and PMMA components. The hybrid construction allows for thinner lens designs without compromising strength or optical quality. Our manufacturing process ensures perfect alignment of optical surfaces across material boundaries. The lenses feature excellent UV stability, with material formulations preventing delamination or yellowing. We offer various surface treatment options including hard coatings optimized for the hybrid material combination. The lenses demonstrate superior resistance to thermal cycling stresses compared to single-material designs. Our quality control includes comprehensive testing of optical performance and mechanical durability. The hybrid design maintains beam pattern accuracy throughout the product lifecycle. We can customize the material distribution based on specific performance requirements or styling needs. All hybrid lenses meet stringent automotive standards for optical quality and safety performance.

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.

Bright and reliable, enhances night driving safety

The automotive headlights we sourced from Geqin have transformed our vehicles’ night performance. The LED bulbs paired with high-quality PC lenses produce a clear, far-reaching beam that illuminates roads and obstacles early. The design includes both low and high beams with precise cutoff lines, avoiding glare for other drivers. They’ve withstood heavy rain and extreme temperatures without fogging up—truly reliable.

Sleek design boosts vehicle aesthetics and recognition

We wanted unique headlights to make our new car model stand out, and Geqin delivered a stunning matrix design. The sequential turn signals and adaptive LED technology not only look modern but also improve functionality. The curved lens shape complements the car’s front fascia, and many customers mention the headlights as a key reason they chose our model. Durable and stylish—exactly what we needed.
