Coining (metalworking) - Wikipedia
Coining is a cold working process similar in other respects to forging, which takes place at elevated temperature; it uses a great deal of force to elastically deform a workpiece, so that 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 – Metallurgical Processes - AZoM.com
Coining is described as a closed die forging process in which pressure is applied on the surface of the forging in order to obtain closer tolerances, smoother surfaces and eliminate draft.
Metal Coining
Metal coining is a forging process by which very fine and intricate details can be created on the surface of a work piece. Coining may be used to control surface quality and detail on parts. Metal coining is often a finishing process for manufactured products.

2023年3月30日 · What is coining in forging? Coining is another closed die forging process that’s used to create very precise shapes and features. It involves applying a lot of pressure to the metal in a very controlled manner to obtain closer tolerances, smoother surfaces and eliminate draft.
Coining | Metalworking: Bulk Forming - ASM Digital Library
Coining is a closed-die forging operation in which all surfaces of the workpiece are confined or restrained, resulting in a well-defined imprint of the die on the workpiece. This article focuses on the coining equipment (hammers and presses), lubricants, and general and special die materials used in the coining process.

Coining is a cold forming process where certain surface forms are produced with low material displacement.
Coining - ASM International
COINING is a closed-die forging operation, usually performed cold, in which all surfaces of the workpiece are confined or restrained, resulting in a well-defined imprint of the die on the workpiece. It is also a restriking operation (called, depending on the purpose, sizing or bottom or corner setting) used to sharpen or change a radius or profile.

Examples of closed die forging operations include heading (formation of a larger cross section at the end of a perform), coining (detailed impressions as in the minting of coins), piercing (production of a hole in a billet), isothermal forging (where tooling and workpieces are preheated to the same temperature), rotary swaging (workpiece is ...
Coining is a cold forming process where certain surface forms are produced with low material displacement. 8.2 Types and applications of coining processes 8.2.1 Coining In coining the thickness of the material in the starting stock is altered. Application: Coin production (Figure 8.1), indenting impressions into badges, coining components for me-

2024年12月2日 · Two closed-die forging operations given special names are upsetting and coining. Coining takes its name from the final stage of forming metal coins, where the desired imprint is formed on a smooth metal disk that is pressed in a closed die. Coining involves small strains and is done cold to enhance surface definition and smoothness. Upsetting ...
