Forging And Extrusion: The Differences You Should Know
If you are new on matters to do with forging and extrusion, the highest likelihood is that you may have some issues in understanding the differences between the two. Ideally, the two processes are part of what leads to the creation of a metallic shape. It is, however, notable that there are distinct differences that you should understand between forging and extrusion. Here are the things you should be familiar with:
The main defining element about forging is that there is the use of pressure on a billet, whereby the intention is to achieve a specific shape. Ideally, the billet is placed on a die, after which pressure is exerted based on the specifications of the designer.
It is further important to acknowledge that forging can be in two different forms depending on temperature. Ideally, the temperature used in hot forging may be above 75 degrees, depending on the shape and type of metal.
The major difference between forging and extrusion is that extrusion involves high pressure exerted on the billet, this time forcing it down the outlet. In other words, whatever that comes after the pressure is exerted is directed to a channel known as an outlet. It is important to note that there is no specific shape that is achieved in extrusion.
In other words, the shapes can be long as you wish and can be of cross-sectional dimensions of different sizes depending on the amount of pressure exerted. This implies that extrusion generates a product that is open for further customization.
Both are forming processes that require the use of force to form the required products. The machines used are almost the same though the setups might be different.
