Coining Sheet Metal

Because coining uses compression to form the part tension failure is unlikely.

Coining sheet metal. Metal coining is a forging process by which very fine and intricate details can be created on the surface of a work piece. Coins metal currency are created with the coining process. Metal coining is often a finishing process for manufactured products. This is a flashless precision forging.

Coining in bending gives similarly precise results. Special coining presses or knuckle presses are often used. Coining also can reduce the metal thickness. In coining the sheet metal is more than just bent it is actually thinned by the impact of the punch and die as it is compressed between them along the bending surfaces fig.

The term coining comes from the idea that when it comes to money each metal coin is made exactly the same as the last despite being mass produced. It can produce sharp crisp corners. 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. Coining has several advantages and disadvantages.

One disadvantage is that it takes a great deal of force to coin metal. Both the punch tip and the punch actually penetrate into the metal past the neutral axis under a high amount of pressure.

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.

Coining dies create the part s shape by squeezing the metal under extreme pressure. We provide a range of metal processing services including tube and steel bending for los angeles california and surrounding areas. For instance if you want to get a 45 degree angle you need a punch and a die with the exact same angle. And a brilliant surface finish.

Coining derives it name from coins as they have to be identical to make fake money distinguishable from the real one. Coining also is a leading producer of gold aluminum and copper bonding wire as well as jumper chips bonding pads tabs heat sinks lead frames solder spheres and cover assemblies for the microelectronics industry. Coining fabrication is a basic type of bending in which the workpiece is stamped between the punch and die. Hansen steel is an expert in metal forming tube bending cutting and fabrication for various markets throughout california.
