Coining (metalworking)

Coining is a form of precision stamping in which a workpiece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. A beneficial feature is that in some metals, the plastic flow reduces surface grain size, and work hardens the surface, while the material deeper in the part retains its toughness and ductility. The term comes from the initial use of the process: manufacturing of coins.

Coining is used to manufacture parts for all industries and is commonly used when high relief or very fine features are required. For example, it is used to produce coins, medals, badges, buttons, precision-energy springs and precision parts with small or polished surface features.

Coining is a cold working process (similar to forging which takes place at elevated temperature) that uses a great deal of force to plastically deform a workpiece, so it conforms to a die. Coining can be done using a gear driven press, a mechanical press, or more commonly, a hydraulically actuated press. Coining typically requires higher tonnage presses than stamping, because the workpiece is plastically deformed and not actually cut, as in some other forms of stamping. The coining process is preferred when there is a high tonnage.

Coining (mint)

In minting, coining or coinage is the process of manufacturing coins using a kind of stamping which is now generically known in metalworking as " coining". This process is different from cast coinage, and can be classified in hammered coinage or hammering and milled coinage or milling.

A coin die is one of the two metallic pieces that are used to strike a coin, one per each side of the coin. A die contains an inverse version of the image to be struck on the coin. Striking a coin refers to pressing an image into the blank metal disc, or planchet, and is a term descended from the days when the dies were struck with hammers to deform the metal into the image of the dies.

Modern dies made out of hardened steel are capable of producing many hundreds of thousands of coins before they are retired and defaced.
