The compound tool differs from progressive and stage tools by the arrangement of the punch and die. It is an inverted tool where blanking and piercing takes place in a single stage and also the blanking punch will act as the piercing die. That means punch will be to the bottom side of the tool and piercing punches to top side of the tool.
A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, [1] as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not. Like molds, dies are generally customized to the item they are ...
The S.I. unit for the mold constant B is seconds per metre squared (s/m 2). [4] According to Askeland, the constant n is usually 2, however Degarmo claims it is between 1.5 and 2.
Up to 0.20% of vanadium is used to retain fine grain sizes during heat treating. Typical applications for various carbon compositions are for W-steels: 0.60–0.75% carbon: machine parts, chisels, setscrews; properties include medium hardness with good toughness and shock resistance. 0.76–0.90% carbon: forging dies, hammers, and sledges.
The term moldmaker may also be used to describe workers employed in fabricating dies and metal moulds for use in injection molding and die-casting, such as in the plastics, rubber or ceramics industries, in which case it is sometimes regarded as a branch of the trade of toolmaker. [2] The process of manufacturing molds is often highly automated.

In the case of square and rectangular components, a minimum of four pins (at the four corners) are required. In the case of cylindrical components, three equidistant pins (i.e. 120° apart) are required. The number of pins required may vary based on the component profile, size and area of ejection.
In this die type, a ring of polymer melt under pressure is forced around the bare wire. Due to the applied pressure of the melt, the opening around the inlet for the bare wire must be very small, on the order of 0.05 mm. The size of the exit opening controls the thickness of the resulting coating.
