Punches and Dies

Punches are simple tools that are forced by a punch press through a workpiece, commonly sheet metal, to create quick, precise holes by shearing. Punches are typically made of carbides or tool steel. Most presses are operated mechanically, but simple hand punches also are used. A punch frequently passes through the material and into a die. A die holds the workpiece, and determines the shape produced on it by the punch. Dies are usually customized to the particular item being produced.

Increase Tool Life with Preventive Maintenance

Deliberately pull a die out of the stamping press for tool maintenance even though it is still producing perfect parts? That’s right.
