Suitable For Automotive Reflector Arrays (LED Headlights, Tail Lights, Turn Signals) | 95%+ Light Reflectivity | ±0.002mm Optical Precision | Works With High-Temp Resins (PC, PMMA)

Engineered exclusively for automotive reflector arrays—where "light reflectivity = driving safety"—this customizable nickel alloy electroplated mold combines two critical advantages: electroforming (for uniform, stress-free optical surfaces) and mirror polishing (for 95%+ light reflection). Unlike standard molds that cause light scattering (reducing visibility), our design delivers ±0.002mm precision for reflector curves and edges, ensuring every ray of light from LED bulbs is directed evenly (no hotspots or dark zones). Built with automotive-grade nickel alloys, it also withstands extreme outdoor conditions (from -40℃ winter cold to 80℃ summer heat) and resists UV damage—critical for long-term reflector performance.

Mirror polishing is the "make-or-break" for automotive reflectors—our process ensures optical-grade smoothness that directly boosts driving safety:

• Multi-Stage Polishing: Starts with 1μm diamond abrasives (shaping the base surface), then 0.1μm alumina (refining), and final 0.05μm colloidal silica (mirror finishing)—resulting in Ra ≤0.005μm, far exceeding industry standard (Ra ≤0.01μm) for automotive reflectors.
• No Light Scattering: A perfectly smooth surface reflects 95%+ of LED light (vs. 85% for unpolished molds), eliminating "dark spots" in headlights (improving night vision) and "fuzzy" tail light signals (reducing rear-end collision risks).
• Consistent Optical Performance: Mirror polishing is calibrated via laser interferometry—every cavity/core has identical reflectivity, so reflector arrays from the same mold perform uniformly (no batch-to-batch variation).

Nickel alloys are chosen for their ability to handle the harsh reality of automotive use—no cracking, fading, or performance loss:

• UV & Corrosion Resistance: Nickel-chromium alloy resists sun UV rays (prevents surface yellowing, which dulls reflectivity) and road salt/rain (avoids rust that distorts reflector shapes)—molds maintain optical performance for 3+ years of outdoor use.
• Thermal Stability: Handles -40℃ to 80℃ (the full range of global automotive climates) without warping—critical for molds used to produce PC/PMMA reflectors (which require high-temperature molding, 180-220℃).
• Wear Resistance: Nickel-cobalt alloy (50-55 HRC) stands up to high-volume production (200,000+ reflector cycles) without scratching the mirror surface—unlike steel molds that wear down after 50,000 cycles.

Every automaker has unique reflector shapes (e.g., curved for headlights, angular for tail lights)—our molds adapt to your exact CAD design:

• Curve & Structure Customization: Replicates complex reflector geometries—from 3D curved LED headlight reflectors (to focus light) to multi-cavity tail light arrays (for sequential turn signals). We accept STEP/IGES files and optimize mold curves for maximum light efficiency.
• Model-Specific Sizing: Supports reflectors of all sizes—from compact passenger car headlight reflectors (φ50-80mm) to large commercial vehicle tail light arrays (200*150mm).
• Optical Tuning: Adjust mirror polish intensity based on your needs—e.g., higher polish (Ra ≤0.004μm) for high-end LED headlights (luxury cars) or standard polish (Ra ≤0.005μm) for economy models (cost-efficient).

Our molds are tailored to the most safety-critical automotive lighting components:

• LED Headlight Reflectors: Produces curved reflectors that focus LED light into a tight beam (no glare for oncoming drivers) — ±0.002mm curve tolerance ensures compliance with ECE R112 (European) and FMVSS 108 (US) lighting standards.
• LED Tail Light Reflectors: Creates multi-cavity arrays for sequential turn signals or brake lights—mirror finish ensures bright, even light that’s visible from 500+ meters (reducing rear collisions).
• Fog Light Reflectors: Molds small, high-intensity reflectors that cut through fog—nickel alloy’s corrosion resistance handles road spray and salt (common in foggy climates).
• Commercial Vehicle Reflectors: Designs large, durable reflectors for trucks/buses—high-wear nickel-cobalt alloy supports 300,000+ cycles (meeting commercial vehicle production volumes).

We collaborate with your engineering team to turn reflector designs into production-ready molds:

• DFM for Optics: Our optical engineers review your reflector CAD files to optimize mold geometry—e.g., adding micro-grooves to reduce resin adhesion (easier demolding) or adjusting curves to boost light focus.
• Material Matching: Recommend nickel alloy based on your production: nickel-cobalt for high-volume models, nickel-chromium for coastal regions (high corrosion), pure nickel for premium optical clarity.
• Prototype Validation: Produce 1-2 prototype molds (12-15 days lead time) to test reflector performance—we measure light reflectivity via spectrophotometry and adjust polishing parameters if needed.

• Optical & Precision Inspection: 100% testing includes:
  • Laser interferometry (measures mirror surface Ra ≤0.005μm);
  • CMM (±0.0005mm accuracy) for curve/edge tolerance;
  • Spectrophotometry (verifies 95%+ light reflectivity).
• Compliance: Meets IATF 16949 (automotive quality standard) and provides full traceability (material certs, polishing logs, electroplating records) for automotive supply chains.
• After-Sales Support: Dedicated automotive engineers advise on mold maintenance (e.g., how to clean mirror surfaces without scratching) and offer 6-month free re-polishing (if surface wear occurs).

Whether you’re designing LED headlights for a new passenger car or tail light arrays for commercial vehicles, our nickel alloy electroplated molds—refined by mirror polishing—deliver the optical precision, durability, and customization your automotive reflector projects demand. Backed by 95%+ light reflectivity and IATF 16949 compliance, they ensure every reflector meets global safety standards and enhances driving visibility
