Upset Forging

Upset forging increases the diameter of the workpiece by compressing its length. Based on number of pieces produced this is the most widely used forging process. A few examples of common parts produced using the upset forging process are engine valves, couplings, bolts, screws, and other fasteners.

Impression Die Drop Forging

Closed die forging is very effective for shaping aluminum, steel, titanium, and a wide range of metal alloys. By enclosing the hot metal inside sets of dies, many kinds of three-dimensional shapes can be produced. This includes simple forms such as cubes, disks and spheres, but it can also be applied to multi-section parts that incorporate thin delicate webs and long, spindly shapes.

Open Die Forging

Open die forging is widely used for the products in small quantity that are simple, rather than complex, such as discs, rings, sleeves, cylinders and shafts. Custom shapes can also be produced with open die forging. The strength of the grain structure will be increased during the deformation process due to the repeated working of the steel billet. Another benefit of open die forging is that the fatigue resistance and strength of products will be improved. Besides, voids could be effectively reduced after open die forging.
