Steel Texture Vehicle Lamp Mould: The Foundation of Consistent Lighting
With 15+ years of expertise in automotive lighting mold engineering, we specialize in steel texture vehicle lamp moulds—engineered to deliver smooth, uniform lighting by combining high-grade steel durability with precision texture control. Unlike plastic or aluminum molds, steel molds maintain stable texture and dimensional accuracy over hundreds of thousands of injection cycles, ensuring every lamp (headlight, taillight, fog light) produces consistent light distribution, no glare, and no uneven brightness. The steel texture (customizable for diffusion, reflection, or light guiding) directly shapes the lamp’s optical performance, making it critical for meeting automotive safety standards (ECE R112, SAE J578) and enhancing driver visibility.
1. Steel Durability: Stable Texture for Long Production Runs
High Hardness & Wear Resistance: S136/H13 steel undergoes heat treatment to 50–55 HRC, resisting wear from abrasive resins (e.g., glass-reinforced PC) and maintaining texture integrity over ≥500,000 cycles. This eliminates "texture degradation" (common in aluminum molds) that causes uneven lighting in late-batch lamps.
Corrosion Resistance: S136 steel’s chromium content (13–17%) prevents rust or pitting from resin additives or cleaning agents, ensuring the mold’s texture stays smooth—critical for transparent PC/PMMA lenses (even minor corrosion causes light scattering).
Thermal Stability: Steel’s low thermal expansion coefficient (11.5×10⁻⁶/℃ for S136) ensures core-cavity alignment ≤0.002mm during high-temperature injection (280–320℃ for PC), avoiding part warpage that disrupts light distribution.
Uniform Texture Replication: Using laser engraving or chemical etching, we create micro-patterns (10–50μm) with 99.8% replication accuracy—ensuring every injected lamp part has identical texture. For example, taillight diffusers with uniform 15μm texture dots produce even red light (no "bright spots" or "dark edges") that meets ECE R112 signaling standards.
Smooth Surface Finish: Ra ≤0.01μm polished steel texture eliminates micro-imperfections (scratches, burrs) that cause light scattering. For headlight lenses, this ensures clear light transmission (≥90% for PC) and reduces glare for oncoming drivers.
Custom Texture for Lighting Needs: Tailor texture to lamp function:
Headlight Reflectors: Mirror-like steel texture (Ra ≤0.008μm) for high reflectivity (≥95%), focusing LED light into a sharp beam.
PMMA: S136 steel’s corrosion resistance avoids chemical reaction with PMMA, ensuring smooth lens surfaces.
Batch-to-Batch Consistency: Steel molds’ dimensional stability (±0.005mm tolerance) reduces part variation to ≤0.1%—critical for automakers requiring 10,000+ identical lamps per model year.
Reduced Scrap Rate: Precision texture and steel durability cut scrap rates to ≤0.3%, lowering production costs for high-volume orders.
Bright, energy-efficient light (LED compatibility), consistent brightness across DRL strips
Our Service Process for Steel Texture Vehicle Lamp Moulds
Lighting & Design Collaboration: Work with your team to define lamp optical requirements (beam pattern, diffusion, reflectivity) and texture specifications. Provide DFM analysis to optimize mold geometry (e.g., adjusting texture depth for taillight diffusion).
Mold Material & Texture Selection: Recommend steel grade (S136/H13/NAK80) based on lamp type and production volume; finalize texture type (laser/chemical etching) via 3D texture simulation.
Prototype Mold & Testing: Manufacture 1-cavity prototype mold in 12–15 days; conduct test injections with PC/PMMA resin. Validate texture replication, dimensional accuracy, and lighting performance (via optical testing equipment).
Batch Mold Production: After prototype approval, produce multi-cavity molds (2–8 cavities) for mass production. Conduct 100% mold inspection (3D confocal scanning, CMM) to ensure texture and tolerance compliance.
Post-Delivery Support: Provide mold maintenance guidelines (cleaning, texture touch-up) and 1-year warranty for mold defects. Offer process tuning for resin parameters to maintain lighting consistency.
Quality Assurance
Optical Testing: Use goniophotometers to measure light distribution, spectrophotometers for color consistency, and haze meters to verify lens clarity (≤2% haze for PC parts).
Mold Inspection: Employ Zeiss CMM (±0.0005mm accuracy) for dimensional checks and 3D confocal scanners (resolution 0.1μm) to validate texture depth and uniformity.
For vehicle lamp moulds that deliver smooth, consistent lighting and long-term production reliability, our steel texture solutions are engineered to automotive standards. Whether you’re developing next-gen matrix headlights or dynamic taillights, we combine steel durability, precision texture, and optical expertise to turn your lighting designs into safe, high-performance reality.
