Custom metal stampings can be used in large automobile components and custom assemblies to micro-miniature parts for medical equipment or electronics.
FREMONT, CA: Custom metal stamping is explicitly made for a given part and its functionalities. Compared to mass-produced stampings, custom metal stamping is used when precision and intricate dimensions are necessary to create a one-of-a-kind product.
This method necessitates creating a specialized metal stamping tool that cuts and shapes the part as it passes through the press. Large components for automobiles and custom assemblies to micro-miniature parts for medical devices or electronics are all possible with custom metal stampings.
Techniques for Shaping Custom Metal Stampings
Stamping is a term that refers to a range of sheet metal forming techniques that can be done in a single station operation where each stroke of the press produces the required form of the metal item or in a series of steps. The following procedures are employed in the press to create the necessary form.
Bending is the process of angular displacement of a sheet metal workpiece to produce a formed feature. In some procedures, one edge of the workpiece is secured while the other edge is bent over a form using a metal tool to develop an exact bend or shape. The metal piece can also be pushed into or against a structure.
When a metal item is drilled through the main metal strip or sheet, the blanking procedure eliminates it from the strip or sheet. The removed material is used to create a new metal workpiece or blank.
Coining is a shaping technique that involves putting a lot of pressure on a workpiece to force it into a die. The metal is then formed into a precise shape by the die, which leaves permanent marks on the workpiece.
Crash or Crush Forming
Only a punch and cavity are used to distort the metal in this technique. These dies have no control over metal flow and are incapable of preventing wrinkling or buckling. They're used to make simple components like brackets and braces out of robust, rigid metals that are less prone to wrinkles than thinner metals.
Cutting is one of the most popular stamping procedures that use exceptionally high force in the stamping press to trim the metal into a portion. Trimming, notching, piercing, blanking, lancing, and shearing are all examples of cutting operations.
Large metal items, like automobile components, are made with a sophisticated drawing die. The procedure involves using a pressure-loaded draw pad to regulate metal flow into a cavity and eliminate wrinkling as the material runs over a forming punch.
