Zhu Cheng Group meets Salvagnini: unmanned lights-out production for the door industry

Founded in 1998, China Zhu Cheng Group is a technology-oriented manufacturing enterprise. Driven by strong production and research capacity and utilizing advanced production tools and equipment, it has evolved into a modern professional manufacturer, providing a full range of security doors. In the 1990s, China Changchun Group got to know Salvagnini in an overseas visit, and in 2000 it introduced the first Salvagnini S4+P4 sheet metal flexible production line after negotiations. The Salvagnini sheet metal flexible manufacturing system significantly improved the stability of Zhu Cheng’s product quality immediately after its introduction. The Salvagnini flexible manufacturing system can complete punching, shearing, bending and handling of sheet metal in a single step. Only one engineer is required to program it in advance, and the whole processing flow does not need to machine semi-finished products in subsequent phases, thus achieving unmanned lights-out production in the true sense.
