Two pieces of material are placed on the die as the machine is actuated. The clamp and punch strike the material, holding it firmly in place.
Once the material is held in place, the punch draws the material into a cup-shaped cavity.
The clamp allows for expansion as the punch forces the material to flare out, locking the material together.
