Raw Materials – The Foundation of Quality
Polycarbonate (PC): Sourced from Germany and Japan.High transparency, impact resistance, and thermal stability.
UV-Resistant Coating: Origin from the Europe (PPG Industries). Prevents yellowing and maintains clarity for 10+ years.
Precision Manufacturing Workflow
-Injection Molding
-
800-ton hydraulic presses with ±0.01mm tolerance.
-
24/7 automated production for consistency.
-Surface Polishing
-
CNC-polished to eliminate micro-defects (Ra ≤ 0.1μm).
-UV Coating
-
3-layer coating applied in dust-free chambers.


Quality Control – Rigorous Testing at Every Stage
-Optical Testing
-
Light transmission ≥ 90% (per ECE R112).
-Heat Resistance
-
500-hour thermal cycling (-40°C to 120°C).
-UV Aging
-
2,000-hour QUV testing for color stability.
