Auto Light Mold
Challenge: Optical-grade surface with zero flow lines, weld lines, or bubbles; UV resistance for 10+ year exposure.
Solution: SPI-A1 diamond-polished cavity, edge-gate with film fan for laminar flow, vacuum-assisted venting to eliminate trapped air.
Result: Light transmittance 92%+, no visible optical defects, passed UV aging test equivalent to 10 years.
