Analyzing the Applications of Cold Forging in Different Industries

by mtelec

Over the last ten years, forging has gained popularity. This is because there is a rise in demand for various high-volume precision parts. The need is exceptionally high in the automotive sector. Therefore, experts have developed a variety of unique manufacturing methods to make these parts. Cold forging is one such process.

The processes of cold forging

Cold forging involves several performing operations. A fracture can be a drawback because of severe deformation during the process of cold forging. That said, some factors impact the success of cold forging. One such factor is the die stress. It can cause deflection and should be considered as a limiting factor.

Even so, the process comes with several advantages. Take a brief look at the advantages of forging.

1. Cold forging provides a better metallic yield

The process of cold manufacturing increases metallic strength through strain hardening. This is mostly possible at room temperature. Unlike its counterpart, hot forging, it results in relatively higher yield strength. This is good for high ductility.

2. Cold forging is economical

Many manufacturers prefer cold forging over other forging types because it is more economical. This is usually in terms of maintaining the parts. Unlike hot forging, it is also time-saving because it is not in high demand.

3. Cold forging is highly reliable

In many manufacturing processes, forgings are known to be more reliable. They are also more affordable compared to castings. Besides, cold forging does not come with defects of different forms during the cooling process. This only means that it is cheaper and reliable.

Other than increasing production efficiency, cold forging also helps save time and resources involved. The forging process also produces reliable parts in one pass process. Thus, using the appropriate approach is beneficial for creating fewer defects.

4. Provides close dimensional tolerances

Also known as cold forming, cold forging processes provide close dimensional tolerances. When working with specific metals, some heat is applied to help enhance malleability. Even though the temperatures are below the crystallization point, cold forging can be used to form different types of shapes and parts.

For that reason, there is no standard process used to shape blanks. Instead, the parts are created via one method or the following combination processes:

Cold forward extrusion, which is also direct extrusion, is a common type of cold forming process. For it to occur, force is applied to the metal blank. This pushes it into the mold.

Backward extrusion where a punch is used to shift a blank to some mold size- A blank then enters the mold. The punch forms a small hold. The blank hole is then shaped around the material.

5. Consistency in every part manufactured

Consistency is a crucial factor to consider in every manufacturing process. Cold forging provides consistency and precise tolerances. It also maintains a steady flow of grains for a better finish. It also enhances durability while hardening the materials used.

Final Thoughts

Precision cold forging is often combined with the finish machining processes. It saved material and machining time. Besides, cold forging offers a consistent as well a precise tolerance for machining.
