The flexible production line introduced from Italy is one of the most advanced sheet metal processing equipment in the world, and also the first real flexible production line in China's domestic elevator industry. It uses advanced numerical control technology, can continuously complete the sheet metal feeding, stamping, shearing, bending and unloading process, to achieve the automation and continuity of production. The unique S4 punching and shearing composite system and universal bending die can ensure the high accuracy of the workpiece processing, so that the processing of elevator car walls, car doors, hall doors more beautiful, effectively ensure the consistency of size and Angle. At the same time, it can also achieve the overall shape of the car wall and door, change the traditional production mode, and increase the stiffness of the car.
