It is performed when a bar stock, round or flat is placed between die rollers which reduces the cross-section and increases the length to form parts such as axles, leaf springs etc. This is essentially a form of draw forging. The rollers have a die embedded in them, and as they compress the metal, they will force it to conform to the die. This form of forging can be made continuous with the use of multiple rollers and dies.
Open-die forging can produce forgings from a few pounds up to more than 150 tons.
Closed die forging of steel, aluminum, titanium and other alloys can produce an almost limitless variety of 3-D shapes that range in weight from mere ounces up to more than 25 tons. Impression-die forgings are routinely produced on hydraulic presses, mechanical presses and hammers, with capacities up to 50,000 tons, 20,000 tons and 50,000 lbs. respectively.
Rings forging process can weigh < 1 kg up to 350,000 kgs., while O.D.’s range from just a few inches up to 30-ft. in diameter. Performance-wise, there is no equal for forged, circular-cross-section rings used in energy generation, mining, aerospace, off-highway equipment and other critical applications
The most common type of forging equipment is the hammer and anvil. Forged parts can range in weight from less than a kilogram to 170 metric tons. Materials that can be formed include, but are not limited to: Carbon steel, Alloy steel, Aluminum, Brass, Copper, Bronze.
Applications of Forging Process: Wide variety of uses in different kinds of Industries，Automobile Industry，Argo-Industry，Aerospace，Hand Tools, Industry Equipment.
