EV smart glass and roof systems require CNC machining of 6061-T6 aluminum and polycarbonate for panoramic roofs, electrochromic frames, and solar panel mounts with glass seating surface flatness 0.05 mm and sealant channel tolerance ±0.10 mm.
Quick Answer
EV smart glass and roof systems require CNC machining of 6061-T6 aluminum and polycarbonate for panoramic roofs, electrochromic frames, and solar panel mounts with glass seating surface flatness 0.05 mm and sealant channel tolerance ±0.10 mm.
Definition
CNC machining for smart glass involves precision framing systems for panoramic sunroofs, electrochromic (smart tint) glass, and integrated solar panels. These systems must maintain perfect sealing while supporting electrical connections and thermal expansion.
How It Works
Roof Frame Machining: 5-axis machining of aluminum frames with glass seating surfaces.
Solar Panel Mounting: Precision machining of PV panel supports and wiring channels.
Electrochromic Frame: CNC machining of conductive frames for smart tint control.
Drainage Channel: Machining water management channels to prevent interior leaks.
