Forgings are precision metal components shaped through the application of mechanical and thermal energy to solid metal, rather than working with molten metal. They are essential in industries requiring parts with exceptional strength and durability, with examples including automotive crankshafts, bearing caps, axle carriers, axle tubes, valve bodies, turbine housings, splines, suspension brackets, spring hangers, flanges, gear blanks, and more.
Forges are specialized facilities where these parts are created using techniques such as hot and cold hammering, stamping, and pressing. Unlike other metal-forming methods, forging produces parts with superior grain structure and enhanced mechanical properties, making it a preferred choice for applications demanding high performance and wear resistance.
Forging processes can be categorized into several methods, including hot forging, warm forging, cold forging, drop forging, open-die forging, impression forging, and press forging. Each technique is chosen based on the desired shape, strength, and production efficiency.
A wide range of metals can be forged, such as steel, stainless steel, iron, aluminum, and titanium. Forging offers unmatched structural integrity, minimizing issues like cavities, porosity, and shrinkage that are common in other processes. This results in components with exceptional strength, reliability, and dimensional accuracy, often rivaling high-cost alloys without requiring extensive alloy customization.
Forging remains one of the most reliable manufacturing methods for industries needing components capable of withstanding high stress and extreme conditions. Partnering with a knowledgeable forging manufacturer ensures access to expertly engineered parts and guidance on selecting the best forging techniques for your needs.
Forgings, also known as metal forgings, are metal parts created through the forging process. They play crucial roles in various vehicles and machinery, including tractors, automobiles, airplanes, engines, missiles, and material handling equipment. Forging is favored for its ability to offer design flexibility while consistently producing exceptionally strong parts with minimal defects. Moreover, forgings often eliminate the need for additional processing steps.
In forging, manufacturers apply compressive force to reshape metal through plastic deformation, altering its grain structure. This force is typically exerted using a hammer and anvil.
There are two primary forging methods: closed die forging (also known as impression die forging) and open die forging. Closed die forging is the more prevalent of the two. In closed die forging, manufacturers use a hammer and anvil to pound preformed metal blanks, known as ingots, into a die or set of dies. These dies replicate a three-dimensional mold of the part being forged. The hammer and anvil completely enclose the workpiece to ensure uniformity, forcing the metal to fill all areas of the die. During forging, manufacturers may preheat metal, but they do not melt or pour it.
