INTERIOR DOOR LINE

GRG designed and manufactured two turnkey interior car door assembly lines for left-hand (LH) and right-hand (RH) panels over 14 months, achieving a cycle time of 47 seconds. Each line produces two model types—front and rear—utilizing advanced ultrasonic welding technology, wire harness assembly, and end-of-line testing (EOLT). The setup includes three welding and five manual assembly stations, supported by 15 pallets with RFID changeover details for efficient operations. The GRG advantage was highlighted by simulation techniques to verify access and cycle times, ensuring optimal performance. Additionally, 3D-printed tooling allowed for off-tool prototyping, enhancing precision and efficiency throughout the assembly process.
