Progressive
Metal Stamping is the process of creating
metal parts by employing multiple metal forming / working
methods. The methods are applied in a series of progressive
steps to produce the final part. Manufacturing steps typically
used in progressive stamping are;
- Coining
- Punching
-
Bending
- Deep Drawing
- Wireforming
- Fine blanking
- Multislide stamping
- Fourslide stamping
Progressive metal stamping
normally incorporate a automated feeding system to process
the metal stamping through the progressive manufacturing
stations or steps. Each stamping step creates a new set
of features. The final manufacturing step is normally a
cutoff or cleanup step for the excess edge material.
Some progressive manufacturing
machine use a cylindrical type feed cylinder that includes
the stamping form or die. Other progressive stamping machine
use a reciprocating motion to manufacture features.
Most metals may
manufactured using the progressive stamping process these
include:
- Aluminum (most alloys)
- Brass
- Steel, Cold rolled
- Copper
- Steel, Galvanized
- Steel, Hot Rolled, Cold Rolled
- Stainless Steel
- Titanium
- Zinc
Dimensional tolerances of metal parts
manufactured by progressive
stamping, should be carefully considered. Most experienced
metal stamping manufacturers should be able to achieve +/-
.010 for most features. Precision stampings or precision
stamped features on stamped parts are possible without post
machining or additional manufacturing steps. Precision stamping
is process controlled, and collaborative design and engineering
is required with the stamping manufacturer to achieve tight
tolerances. |
