A lot has been discussed about the hot forging method, but not has been said about the negative factors or the cons that come with this forming method. That’s what we have for you in this guide. There are several disadvantages that come with hot forging, and some are addressed by other forging methods such as cold forging.
Before we go into the details, it is important for the buyers to note that most of these cons can be reduced by sourcing the parts from a reputable manufacturer. You can go to this website for one of the hot forging manufacturers.
Here are some of the most common disadvantages of hot forging:
Warping
One of the biggest challenges of hot forging is the warping of metals. The heating of most of the metals makes them a bit soft, and this exposes them to warping. This means the forged part may not have the steadiness needed and may go out of shape hence making them difficult to work with. A good example is the warping of construction metal frames.
However, it is essential to note that the problem usually occurs when some of the hot forging processes are not done properly. If the heating and forging or even cooling system is not done properly, then you are likely to have a problem with the warping of the forged parts.
Therefore, the quality of the process of cold forging is one of the crucial factors that you need to consider. Make sure that the cooling process is done properly to reduce or even get rid of this problem.
Less Tolerance
The tolerance of the metal parts or products that have been hot forged is less compared to other methods such as cold forging. This is mainly because of the softness of the metals that have been hot forged, as intense heating can reduce the hardness of the billet.
This means hot forged machine parts may not provide the best hardness and strength features that are provided by cold forging. This limits these parts for hard and some of the demanding conditions.
Expensive
Compared to cold forging and warming forging, hot forging is the most expensive of all. The process and steps needed to process parts made from this method are long and consume many resources. A food example is the heating and finishing work. This simply means that the end products will be a bit expensive.
