Precision metal punching – not to be confused with metal stamping – is the process of creating custom shapes of varying sizes within a sheet of metal. In many instances, this process can be used in the place of laser cutting.

HOW DOES IT WORK?

When punching a workpiece is placed on the lower tool, the die. The upper tool, the punch, is pressed against the workpiece with an applied punch force. Depending on the design of the workpiece, one or more subsequent strokes are done.

When punching out a hole the material is exposed to shear between the punch and the die. During the punching process the material is displaced and then loosen completely by material failure. This gives both stamped detail and bore the typical cut surface caused by punching consisting of a smooth surface where the material has slid and a rougher surface where the deformation occurred.

Precision stamping differs from ordinary punching by a clamping ring, which presses down and locks the plate around the contour which minimizes the fracture surface. This causes higher tolerances while minimizing deformation around the hole. Clamping ring also ensures that the sheet detaches from the punch if it’s wedged in the plate after the stroke.

There are a variety of punching tools that can do everything from cutting straight lines and creating threaded holes to engrave and carry out bending operations.

In cases where the tools are designed to carry out compression forming, the sheet is deformed by plastic deformation.

Usually the workpiece is moved while the tool maintains its position and can rotate.

WE PRECISION PUNCH MATERIALS SUCH AS:

• Stainless steel
• Galvanized Steel
• Aluminum
• Iron
• Diamond Plate
• Brass

Precision Metal Stamping Processes

Xiange offers the following precision stamping processes:

 Progressive die stamping.

This metal stamping process employs multiple

workstations that each carry out a different function to produce a metal part.

Compound die stamping. 

With this method, the compound die performs multiple punches or cuts in one stroke.

 Deep drawn stamping.

This process is typically used to make cylinder-shaped metal components by feeding a flat metal coil into a press with multiple tooling stations that carry out repeating operations on the workpiece.

Piercing stamping.

This is a shearing process used to pierce raw metal. This method uses a machining tool to create a circular or other shaped hole in the workpiece.

Short-run stamping. 

For short-run stamping, we insert sheet metal between the punch and die. We then use a metal press to shape the metal based on your specifications.

Single-stage stamping. 

Using manual dies, single-stage stamping involves carrying out one operation on a part per stroke of the die.

No matter what your specific needs are, we have a precision stamping process that will work for you. We pride ourselves on our ability to work with our customers to come up with the best precision stamping solution for their needs.
