Utilizing high-transmittance PC/PMMA composite material with nano-grade mold polishing technology to achieve ultra-precision wall thickness control (≤0.2mm) for automotive light guide strips. Multi-color injection molding combined with finite element analysis (FEA) effectively eliminates sink marks in thick-walled parts (6-15mm thickness), achieving a production yield rate of 99.3%. Passes rigorous environmental testing (-40°C to +120°C) to meet automotive OEM standards.
