Stamping

Custom Manufacturing of Castings, Forgings, Stampings and Machined Parts.

Stamping is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping press, blanking, embossing, bending, flanging, and coining.

Stamping is usually done on cold metal sheet. See Forging for hot metal forming operations.

  • Bending - the material is deformed or bent along a straight line.
  • Flanging - the material is bent along a curved line.
  • Embossing - the material is stretched into a shallow depression.
  • Blanking - a piece is cut out of a sheet of the material, usually to make a blank for further processing.
  • Coining - a pattern is compressed or squeezed into the material.
  • Drawing - the surface area of a blank is stretched into an alternate shape via controlled material flow.
  • Stretching - the surface area of a blank is increased by tension, with no inward movement of the blank edge.
  • Ironing - the material is squeezed and reduced in thickness along a vertical wall.
  • Reducing/Necking - used to gradually reduce the diameter of the open end of a vessel or tube.
  • Curling - deforming material into a tubular profile. Door hinges are a common example.
  • Hemming - folding an edge over onto itself to add thickness.
