Why Is Cold Forging Very Popular Now?


Forging is a manufacturing procedure where metal is shaped by applying localized compressive forces. The forces are delivered to the object or metal using a hammer. More often than not, a power hammer or a die is applied. There are two types of forging. They are defined depending on the temperatures at which the action is performed. They are; cold and hot forging. Cold forging is usually done at room temperature, like in warm extrusion. In this process, the metal bars are inserted into a die. They are then squeezed with a second die or pounded with a power hammer. After this, the product forms into the desired shape.

Note that, depending on the desired shape and type of product being manufactured, the metal may have to go through multiple dyes. It may also be subjected to several strikes in succession to achieve the desired shape.

Advantages of cold forging

Cold forging is a prevalent manufacturing process. Below are some reasons why this is the case;

1. Temperature

As mentioned earlier, cold forging occurs at room temperature. This is a significant advantage because manufacturers do not have to incur additional costs for heating. This also means that the manufacturing process can be done faster because there is no need to allocate time for heating. In simpler terms, the fact that no heat is required makes the process simpler, more cost-efficient, safer, and faster.

2. Quality

Another benefit of this cold forging manufacturing process is that it helps produce high-quality products. According to avid users of the process, cold forging produces better surface finishes than its counterparts. This is mainly because there are fewer contamination risks and problems. Since the metal bars are exposed to the compressive forces in their natural solid-state, there are fewer chances that they will combine with other materials. This is the reason why there are fewer contaminations risks.

This process also offers superiors dimensional control. Since the metal remains in its natural state during the entire process, it is easier for the manufacture to achieve the required dimensions. This is one of the primary reasons why it’s one of the most popular forgings and manufacturing forms.

Additionally, cold forging allows the manufacture to impart directional elements of properties to the metal under manufacturing. This freedom will enable you to achieve what you want with the least levels of complications.

3. Cost

Another significant benefit of cold forging is that it is highly cost-efficient. The fact that no heating is required significantly reduces the cost of the process. The fact that it is a less intricate process also plays a role in the low price.

Final word

While cold forging has many advantages to offer, it also has its drawbacks like any other manufacturing process. For instance, the process may be stressful, mainly if highly ductile metals are applied. The method also requires highly powerful machinery because it involves a lot of force and pounding. However, even with the drawbacks, the advantages of cold forging are still more significant.
