Sonic weld for Hardtrim door reinforcement

The client required a station for welding together two plastic parts inside a door’s frame, in order to serve as reinforcement. The station required clamping a large door frame while minimizing depth.
LG AUTOMATION designed a station that leveraged a lift system so that the door frame could be placed vertically on their nests, therefore maintaining ergonomics due to the door frame’s size.
The station integrated Dukane ultrasonic welding systems, as well as Allen Bradley PLC & HMI and Keyence safety light curtains. The station was capable of welding multiple points on the door reinforcement, as well as processing LH and RH variants simultaneously.
