Precision Metal Stamping Deep Drawn Process

Commercial applications of this metal shaping process often involve complex geometries 
 
with straight sides and radii.
 
 In such a case, the term stamping is used in order to distinguish between the deep drawing 
 
(radial tension-tangential compression) and stretch-and-bend (along the straight sides) components. 
 
Deep drawing is always accompanied by other forming techniques within the press.

Often components are partially deep drawn in order to create a series of diameters throughout the component (as in the image of the deep draw line).

Commercial applications of this metal shaping process often involve complex geometries with straight sides and radii. In such a case, the term stamping is used in order to distinguish between the deep drawing (radial tension-tangential compression) and stretch-and-bend (along the straight sides) components. Deep drawing is always accompanied by other forming techniques within the press. These other forming methods include:

· Beading: Material is displaced to create a larger, or smaller, diameter ring of material beyond the original body diameter of a part, often used to create O-ring seats.

· Bottom Piercing: A round or shaped portion of metal is cut from the drawn part.

· Bulging: In the bulging process a portion of the part's diameter is forced to protrude from the surrounding geometry.

· Coining: Material is displaced to form specific shapes in the part. Typically coining should not exceed a depth of 30% of the material thickness.

· Curling: Metal is rolled under a curling die to create a rolled edge.

· Extruding: After a pilot hole is pierced, a larger diameter punch is pushed through, causing the metal to expand and grow in length.

· Ironing / Wall Thinning: Ironing is a process to reduce the wall thickness of parts. Typically ironing should not exceed a depth of 30% of the material thickness.

· Necking: A portion of the part is reduced in diameter to less than the major diameter.

· Notching: A notch is cut into the open end of the part. This notch can be round, square, or shaped.

· Rib Forming: Rib forming involves creating an inward or outward protruding rib during the drawing process.

· Side Piercing: Holes are pierced in the side wall of the drawn part. The holes may be round or shaped according to specifications.

· Stamping / Marking: This process is typically used to put identification on a part, such as a part number or supplier identification.

· Threading: Using a wheel and arbor, threads are formed into a part. In this way threaded parts can be produced within the stamping press.

· Trimming: In the Trimming process, excess metal that is necessary to draw the part is cut away from the finished part.
