Vertical Integrated Operation Process
Tong Lung utilizes progressive die stampings equipment - state of the art press technology to maximize efficiency and give us accurate consistency. Progressive die presses stamp metal using a forming method that can encompass bending, cutting, punching and several other ways of modifying coil sheet steel or brass. The automatic feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. Each station performs one or more operations until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web. Tong Lung has production plants in both Taiwan and the Philippines to meet our customers’ needs.
