AUTOMOTIVE DOOR ASSEMBLY

GRG developed an innovative assembly line for EV door assemblies, including front doors (left and right), cargo doors, and fenders over 12 months, achieving a throughput of eight sets (24 doors and 16 fenders) per hour. This project involved installing new assembly line equipment and retooling hemming equipment while preserving space for a future fourth door. The system integrated all common joining technologies, such as spot welding, MIG welding, projection welding, adhesive application, dimpling, and hemming. GRG's approach combined reused and new equipment, allowing for prototyping before the production launch, resulting in a streamlined design that maximized operational efficiency while minimizing floor space.
