[0002] The hemming of the door water cut is an important link in the automobile manufacturing process. It involves the treatment of the door edge, aiming to improve the sealing performance, aesthetics and structural strength of the door. This process usually includes precise cutting, hemming and pressing of the door edge to ensure the tight combination of the door and the vehicle body, and at the same time improve the overall quality of the vehicle.
