Craftsmanship
Metal Stamping Pressing
There are several different types of stamping presses, all of which have the same function. The press has a ram that applies downward force against the sheet of metal that rests on the bed of the press.
Forces in Stamping
Presses take several shapes and forms and depend on some type of power to provide stamping force. Mechanical presses exert force using a flywheel, single gear design, double gear design, or some form of eccentric gear design. Hydraulic presses are powered by a hydraulic pump and hydraulic cylinder that drive the ram downward.
Stamping Dies
Stamping dies shape a metal sheet using a punch that pushes the metal sheet through the die. Punches can be single or multistage depending on the requirements of the final part. With single-stage (or single-stroke) stamping presses, one stroke of the ram produces the desired shape. Multistage stamping presses shape a metal sheet with progressive stamping.
Finishing Options for Metal Stamping
Parts produced using metal stamping are subjected to secondary processes designed to plate, clean, heat treat, or deburr the finished piece. There are several different value added services based on one's metal-stamping part requirements.
