Extrusion And Forging: Everything You Need To Know
The truth is that most people think that extrusion and forging are similar processes. Well, in as much as there are some similarities, extrusion and forging are two different processes. As a newbie, it is in your interest to ensure that you understand all the differences between extrusion and forging. That way, you will not have a hard time doing shopping for the parts that you need. Here are important things that you should know about extrusion and forging:
Preliminary vs. Final Product
One of the major differences between extrusion and forging is that extrusion is more of a preliminary process, while forging is a final procedure. In other words, the billet is first undertaken through a hitting or pressuring session without a particular shape in mind. Therefore, extrusion can lead to the formation of different shapes and dimensions depending on the pressure exerted.
On the other hand, forging is more of a final product stage since it entails the formation of a specific shape. In this case, the manufacturer has already established the shape that is needed; hence the process is to ensure that the specific form is achieved. Only room for minimal customization is left in the forging process.
Both Processes Require Impact and Pressure
The similarity between extrusion and forging is that pressure and impact are required. The extrusion process does not necessarily work along with the stipulated shape or formation. However, the billet must be subjected to pressure for deformation to be achieved. On the other hand, forging equally requires some impact and pressure. In this case, there is a pre-determined shape that must be achieved. Therefore, pressure and impact on billet in the forging process are articulated to precision.
Cold and Hot Processes Applicable
In both cases, the process can be either hot or cold depending on the preference of the customer or the stipulated output by the manufacturer. Cold forging and extrusion take place at room temperature, while hot extrusion and forging take place in extremely hot conditions.
