Open die forging

Introduction:

Open die forging is a process where the material is not confined laterally as in closed die forging; it is instead performed between two flat dies that have no impression made in them. In open die forging, the movement of the work piece is instrumental to forging the metal into the proper shape. Depending on the capabilities of the forging shop, the size of open die forgings is limited only by the size of the original stock. Philadelphia Forgings offers open die forgings in weights ranging up to 80,000 pounds.

Materials Used for Open Die Forging

Many types of metals can be forged through the open die process, however, among the most common are carbon steel and alloy steel as well as stainless steel, copper alloy, high temperature alloy, Inconel®, and many more. To see all of the materials that are available through Philadelphia Forgings, please visit the forged materials section.


Benefits of the Open Die Forgings

  • Develops High Strength

  • Has a Long Service Life

  • Decreases Porosity

  • Aligns Grain Flow

  • Achieves Fine Grain Structure

  • Improves Mechanical Properties

  • Can Forge Extremely Large Products


Products created through open die forging are inherently superior in strength and durability than parts that are machined or welded. Open die forging changes the metal to the desired shape while breaking up the cast structure and producing finer grains. Furthermore, low density areas, microshrinkage, and gas porosity are consolidated which improves the mechanical properties, enhances the density, and aligns the grain flow. Advanced forging shops can produce unique shapes, making open die forging an excellent choice for providing custom metal parts.

Cold forming
In contrast with hot forming, cold forming (a.k.a. cold forging) can be done without heating the metal to extremely high temperatures which makes it a much more economical and environmentally friendly way to work with metal. Precision cold forming technology has been around for many years and is gaining popularity due to its ability to reduce costs, increase efficiency and improve product quality while at the same time being environmentally friendly. It can produce intricate designs such as multiple surface profiles which traditional forging methods are unable to do thus increasing efficiency by reducing equipment duplication.
Close die forging
Close die forging
Sometimes referred to as impression die forging, closed die forging is a manufacturing process through which precision parts can be produced from a wide range of metals and alloys. Non-ferrous alloys like brasses and bronzes are the most common materials; but aluminum alloy, carbon steel, stainless steel, and alloy steels can also be worked through this process.  Closed die forgings can be produced in essentially any 3D shape, including complex part designs. And while the process is most often used to produce smaller, high tolerance parts, impression die forging can be used to create parts weighing thousands of pounds.
