Fundamentals of Metal Stamping

Metal stamping is a versatile and extremely efficient process that converts flat metal sheets into precise shapes and forms utilizing techniques such as bending, piercing, blanking, and coining.

Basic Process Steps

1. Blanking:Initial cutting or punching of the flat metal sheet to create a blank.
2. Piercing:Creation of holes or cutouts in the blank for specific features.
3. Forming:Shaping the blank into the desired form using tools and dies.
4. Bending:Folding or shaping the metal to achieve the desired geometry.
5. Coining:Precision stamping to improve surface finish or add specific features.

Key Components and Tools

Stamping Die:Tool for shaping or cutting the metal into the desired form.
Punch:Tool used to create holes, cutouts, or shape the metal.
Press:Machine applying force to the metal against the die.
Feeder:Mechanism for advancing the metal sheet through the stamping process.
Stripper:Device to remove the formed part from the punch.
