Laser Welding

Laser welding is a method where laser light is used to generate heat at the interface with the welding target. When laser welding is used for resin, “light-transmitting resins (thickness 0.5mm)” and “light-absorbing resins (thickness 0.8mm)” are combined. Laser welding is possible with SUMIKAEXCEL PES since it has excellent light transmittance.
