Press Forging

Forging is a method of manufacturing that involves the manipulation and shaping of different metals. Compression is used in a number of different ways to shape the metal and can be carried out in cold, warm and hot conditions.

Press forging is a method of forging that involves the slow and continuous application of pressure on the workpiece. This method differs greatly from the heavy and quick blows used in drop and hammer forging. The contact of the workpiece in the die is measured in seconds whereas drop forging and hammer forging is measured in milliseconds. Press forging can be carried out either hot or cold.

The Advantages and Disadvantages of Press Forging

There are many advantages of press forges but the biggest is its ability to deform the workpiece. Hammer forging can only affect the surface of the workpiece whereas press forging can change the shape and interior of the workpiece at the same time. Press forging is a little more controlled than hammer forging and gives us a better knowledge of a part’s strain rate - that is how much pressure will cause manipulation of the part.

Another advantage of press forging is that it is more efficient. During hammer forging, the hammer absorbs a lot of the energy that could otherwise be focused on the workpiece. Press forging allows great efficiency and more control over the forging of the piece. Press forging can also be used to perform a number of different kinds of forging including impression-die press forging and open-die forging.
