Metal stamping techniques
The low-cost, high-speed, high precision manufacturing processes associated with metal stamping involve the application of diverse techniques, such as:
Blanking
The blanking process involves the removal of a workpiece from primary material to create the desired form. Unlike punching, the removed workpiece becomes the desired shape or blank.
Punching
This technique refers to the use of a die and a punch to cut sheet metal into the required form. During punching, the punch enters the material attached to the die and dispels pieces of metal to create the desired form in the remaining workpiece.
Coining
This technique involves the placement of the material between a die and a press or punch. The material is squeezed with extreme force during the press stroke to generate fine features and tolerances on the surfaces of parts.
Bending
Bending refers to processes that form sheet metal into desired bent shapes, which are generally the L, U, or V-shapes. The bending process is applied above the material's yield point and around a single axis to form the desired shape.
Flanging
The flanging process involves the use of a die and a flange or flares produced by a flanging tooling section on a workpiece. The flange portion of the tooling and die form the desired shape in the workpiece.
Drawing/Forming
The drawing and forming stamping process involves the use of compressive force to form sheet metal into a cavity or produce a shaped form by wrapping the workpiece over the desired shape in the die.
Embossing
The embossing process involves the use of a die and a pressing or stamping machine to apply the shaped die onto the material. The embossed pattern or designed form is then imprinted on the workpiece.
Curling
The curling process is used to eliminate sharp edges or form sharp edges into hollow rings according to a specific design. Once performed, curling also increases the moment of inertia at the curled end of the workpiece.
Piercing
The piercing process involves punching or cutting out holes of closed shapes in a workpiece. The punched-out portion is discarded and the pierced pattern forms the end-use part.
These diverse metal stamping techniques are done individually and can be combined or done in multiple operations to form the intricate parts a project requires. The peculiarities of individual projects are the major determining factors when choosing which metal stamping techniques to apply.
For example, a simple bent design can be developed using bending while intricate tooling sections may combine flanging and piercing or any one of the other techniques outlined above.
