Electronic stampings can be made from a variety of sheet metal materials, including copper, titanium, stainless steel, and aluminum. As a result of the variety of materials and methods that can be used to form electronic stampings, there is a correspondingly vast range of applications and industries that they are utilized within including: electronics, especially, for use as lead frames, bandolier pins, connectors and springs; automotive, to be used for parts such as braking parts, oxygen sensor, fuel delivery systems, air bag systems and bayonet sockets; and industrial manufacturing, to be utilized as various parts for electric motors such as stepper or servo motors that are essential for many types of automation equipment.
While there are a variety of metal stamping processes that can be used in order to form electronic stampings, there are a few methods that are more commonly used than others. Two of the more common metal stamping methods for forming electronic stampings are fourslide stamping and deep drawn stamping. In the fourslide stamping process, there are four sliding tools coming each from their own direction at the metal blank, typically a form of flat sheet metal, in order to bend the metal around a vertical mandrel and thus into a complex shape. A timed mechanism known as a cam is used in order to regular the movement of the sliding tools. In the deep drawn stamping process, there are three essential components: the die, the punch and the press. A die is a press tool for cutting or forming material, and is a cavity that is shaped as a mirror of the desired end product. To begin deep drawn stamping, the blank, also typically flat metal sheet, must first be moved over the die, and is then held by a "blankholder". Once the blankholder has immobilized the blank, the process begins to occur with the introduction of the punch, which is used to drive the blank into the die cavity and thus create the desired shape. In order to be classified as deep drawn, the depth and length of the part must be greater than one-half of its diameter.
