Metal stamping services are complicated in nature and require a great deal of detail and professionalism to perform well. Not to mention the need for state-of-the-art equipment. While that’s all well and good, metal stamping can be a convoluted phrase for many, so today we’ll break down just what exactly metal stamping is.

What is Metal Stamping?

In stamping, flat sheet metal is placed into a stamping press, either in coil form or blank form. A press and die surface mold are then used to shape the metal.  Some techniques used in stamping include punching, blanking, embossing, and coining.

Tooling must be designed using CAD/CAM technology before the material can be stamped. Each punch and bend must be designed as precisely as possible to ensure proper clearance and optimal part quality. In many cases, the design process involves a large number of parts in a single 3D model, so the process becomes complex and time-consuming.

Deep Draw Stamping

In deep drawing, a sheet metal blank is pressed into a die via a punch and then shaped. Drawing a part with a depth greater than its diameter is what gives it the name “deep drawing.” It is a cost-effective alternative to turning processes that usually require more raw materials, and is ideal for creating components that need several series of diameters. Examples of deep-drawn products include:

  • Components for vehicles
  • Various aircraft parts
  • Electronic relays
  • Cooking utensils and equipment

Short Run Stamping

For prototypes and small projects, short-run metal stamping requires minimal upfront tooling expenses. Manufacturers bend, punch, or drill the part using a combination of custom tooling components and die inserts after the blank has been created. Short-run production can be more cost-effective for many projects, especially those requiring rapid turnaround, due to the custom forming operations and smaller run size.

Metal Stamping Service Techniques

Although the process of setting up and designing for metal stamping is lengthy, once it is in the production phase, these operations typically move quickly. Stamping is a process that is suitable for both short and long runs, and it may be combined with other metal forming operations or techniques, which we’ll now break down.

Punching and Blanking

Punching and blanking are processes of cutting material with a die. During punching operations, a scrap piece of material is removed from the workpiece as the punch enters the die, leaving a hole in it. By contrast, blanking involves removing a workpiece from the primary material, thereby creating the desired workpiece.

Embossing

Embossing is a technique used to create a raised or recessed design on sheet metal by pressing the raw blank against a die that contains the desired shape, or by passing the blank through a roller die.

Coining

Coining is a bending procedure that stamps a workpiece after it has been placed between a die and a punch or press. The punch tip penetrates the metal during this action, resulting in repeatable, accurate bends. In addition, the deep penetration reduces spring-back effects by relieving internal stresses in the metal workpiece.
