Automotive Headlamp Reflector Mold Polishing: Achieving SPI A1 Mirror Finish for DLP and ADB Systems
Automotive headlamp reflector mold polishing to SPI A1 mirror finish (Ra ≤0.012 μm) is a critical enabler for DLP (Digital Light Processing) and ADB (Adaptive Driving Beam) adaptive headlamp systems that require precision reflector surfaces to achieve the optical efficiency, beam pattern accuracy, and thermal stability demanded by modern automotive lighting regulations including ECE R112 and SAE J581
