Also known as smith forging, open die forging uses simply-shaped, non-encompassing dies to hammer or press a metal workpiece into a certain shape. It is distinct from closed-die forging, in which the dies fully enclose the workpiece when they are brought together. The open die forging process allows for larger products to be forged than other types of forging - up to 150 tons and 80 feet long or more.

Open Die Forging
Open die forging is used most often to produce round, square, rectangular, and hexagonal bars, beams and other basic shapes. Other common products formed using open die forging include spindles, hubs, mandrels, step shafts, metal shells, simple pancake forgings and pierced blanks. Since tooling tends to be simpler and lower in cost for open die forges than for closed die forges, open die forging is better suited for lower volume production runs and for creating unique forged items. The pressure applied during the forging process gives metal improved grain structure, higher density, decreased porosity and therefore additional strength and longer service life as compared to cast metal products. Open die forging works well with any metal, including carbon steel, stainless steel, copper, nickel, aluminum and titanium. Industries that benefit from open die forgings include aerospace, automotive, material handling, marine, military, cement, electronics and home appliances.
