There is a range of many manufacturing processes that can be used on sheet metal stampings. The processes range from using a machine press to punch, coining, blanking to bending among others. A single stroke can be enough to make the desired form in stamping. Other times many stages are necessary. Stamping is commonly performed on metals but it can also be done on polystyrene and a few other materials.
Among the stamping operations that can be done on metals is bending. Bending is a process used in manufacturing that produces a U shape, V-shape or channel shape on metals. This is usually along a straight axis. The equipment used to do this includes brake presses and box and pan brakes.
Blanking and piercing is another process of stamping. A punch and die are used in modifying webs. The piece that is punched out in piercing goes to waste while the piece punched out during blanking is known as a blank and it is used.
Coining is a precision operation of stamping. A work piece is subjected to high stress to make plastic flow on the surface. In metals plastic flow work hardens the surface and reduces the surfaces grain size. The material inside retains its ductility and toughness. Coining is used when the requirement is very fine features.
Embossing is a very economic and diverse method of stamping. A malleable metal is hammered to shape. This is done from the reverse side to crease a design in low relief. Chasing is a reverse process that is used to finish up the embossing.
Progressive stamping, drawing and forming are other methods that can be used in stamping. The process of stamping is calculated by simulation. Simulation technology detects splits, wrinkles and material thinning by application of non linear finite element analysis. This technology helps the industry in saving time and cost.
