Also referred to as impression die forging‚ closed die forging differs from open die forging in that the metal is shaped completely inside the walls of two dies that come together. Your products are brought to a virtual “near net shape” of your final product.

Although there are tooling charges associated with the closed die forging process‚ these costs are recovered many times over by the cost savings listed below.

There are 4 distinct advantages associated with closed die forgings and they include:

• The ability to make complex shapes with closer dimensional tolerances.
• The production of parts that are “near net shape” reduces the amount of input material that goes into the product and offers cost savings on raw material.
• By producing “near net shape” parts‚ the machining requirements are greatly reduced over that of the open die forging process offering further cost savings per part.
• The cost of tooling over higher volume is insignificant in the piece price‚ therefore offering the most economical solution for higher volume production programs.

Although initial deliveries may be longer than those in the open die forging process‚ typically a release program accompanies this process and delivery dates can be set up in advance.
