Deep Drawn Metal Stamping of a Galvanized Steel Bus Roof Cap

As a metal stamping manufacturing source for the transportation industry, Dekalb Tool & Die, Inc. manufactures galvanized steel roof caps for buses, manufactured with eight different hole configuration variations. The main process used in manufacturing this cap is deep drawn metal stamping utilizing Dekalb Tool and Die's 1,800 ton large double action press, stamping a 12" deep draw into a 52" x 112" galvanized steel blank with a .047" (18 ga.) thickness.

After deep drawn metal stamping, DeKalb Tool & Die uses a precision Mitsubishi VZ-1 5-axis laser for the laser trimming and hole creation process. The use of the laser eliminates the need for an additional trim die thus creating lower tooling costs for the customer and a more efficient production run with the requirement for multiple variations. Working with one of Dekalb Tool and Die's finishing production partners, the galvanized steel roof cap metal stampings are then finished with a powder coat, and the finished metal stampings are shipped and delivered to Dekalb Tool & Die's customer located in the Southeastern U.S on a Dekalb Tool and Die truck.
