- 700BC: The first known metal stampings produced.
- 1550: A new process developed involving as many as twelve men to turn a large screw press to form metal into coins.
- 1880’s: Metal stamping credited for producing mass quantities of bicycle parts at cheaper cost than forging.
- 1900’s: Henry Ford resisted the use of stamped parts, but when the Ford Company outpaced the production of forged parts, he turned to the metal stamping process to meet demand.
- Today: Metal stamping is the backbone of metal manufacturing. The process continues to evolve to move more metal in one press stoke.
The Metal Stamping Process: Equivalent to a Hammer & Anvil
Metal Stamping involves placing flat sheet metal, in either coil or blank form, into a punch press. The operator sets up a die designed for a specific part in the press. Once the press is set up to run, it forms the metal into the desired shape with each up and down stroke.
The metal stamping process can be a single stage operation where every stroke of the press produces the desired form on the metal.
Or metal stamping can involve a progressive process. With the progressive process, steel advances through different stations of the die.
Depending on the complexity of the part, the number of stations is determined and could include punching, blanking, bending, coining, embossing, and flanging. At the end of the process, the completed part is produced all in one die.
