The materials, equipment, and processes used in the metal stamping industry have proven to be less costly than the original methods of forming metals and alloys into definite shapes. Metal stamping is the method of bending, clipping, and molding sheet metal or coil metal by stamping and pressing the material into the desired forms. The shaped metal is plated with nickel, tin, or some other metallic elements to protect it from corrosion. The most commonly used metals are steel, aluminum, zinc, and nickel. They are low cost, strong, durable, hard to break, portable, and non-toxic.

The precision machining industry in North America has been on the decline due to two factors: the chronic inflation in the price of raw materials and the transportation of same, and a high level of outsourcing to China and India. Outsourcing hasn't struck the metal stamping industry as profoundly thanks to the proximity of the Great Lakes, around which it is concentrated.

The two sections into which the metal stamping Industry is segregated are Mechanical and Hydraulic Metal Stamping. The force produced by hydraulic presses is programmed and are best used for doing the aforementioned deep drawing because they can apply full tonnage over the complete length of the stroke. A hydraulic press is powered by a hydraulic pump to a cylinder or cylinders that drive the slide down. With the pressure preset, a valve can activate pressure reversal so no overload can occur. With this press design and its applications, the die tends to guide the press, so the guiding systems do not have to be as accurate as with a mechanical press that uses a progressive die. A die is a press tool with upper and lower halves that come together under pressure to create the shape of the metal. The upper member is attached to a slide and the lower one is bolted to the "bed" (also called a
