Cold Forging Using Impression Die Forging Process to Achieve Precise Results

The most common process of cold forging at or near room temperature is called impression die forging, also known as closed die forging.  This method places the metal into a die, and then utilizes a hammer to pound it in a rapid sequence, forcing it into the die. The die is the customized mold tailored and engineered to the customer’s design, and during the forging process of deforming the metal material, the desired shape of the metal is achieved by forcing it into the shaped cavity.

Softer metals such as aluminum and carbon and standard alloy steel are most commonly used for cold metal forging since they are more easier to shape at a cold temperature. The impression die forging technique involved in cold forging is advantageous economically since less material is wasted and more precision can be achieved that requires little finishing work. In other words, when the impressions are contained very well in the die, the results would be close tolerance products.
