What is the purpose of cold forming of metals?

Cold metal forming is a machining process involving the modification of metal surfaces/parts. What is it used for? It is used for the purpose of reducing their thickness, but not only. Let’s take a closer look at this functional process in which we at Cama Srl specialise.

The functionality of profiling

This operation is carried out by passing the metals between several rollers placed one after the other. The process takes place continuously at room temperature. To be more specific, it is useful to say that the metal is passed between a pair of rollers placed at a shorter distance than the thickness of the metal itself. In this way, passing between them, the material is forced to laminate and therefore to reduce in thickness. The passage can be carried out several times until the desired thickness is achieved.

Cold forming of metals is a very useful process within many companies, as it allows complex profiles to be produced to size and to drawing. We at Cama Srl use it in particular for the production of seat rails and other types of metal profiles that are essential for certain industries.

Characteristics of machinery used for cold forming of metals

As mentioned above, cold forming is carried out by passing the sheet metal between several rolls. These rollers are implemented in special machines and are responsible for deforming the metals, changing their shape and size. Generally, the rolls are different from each other: in this way, they gradually allow the product to have the desired shape. The rollers are capable of rolling the workpieces and also of imprinting perforations, embossing and notches on the metal.

Cold forming of metals is normally carried out by numerically controlled machines. These significantly reduce the possibility of error and are supported by an operator. The operator’s main task is to adjust the rollers according to the type of process in progress and the desired result.

Where is this processing used?

Metal forming is mainly used in the metallurgical and metalworking industries, but is also widely used in tool manufacture. It is also used for the production of components for household appliances as well as for the creation of car frames.

The advantages of cold metal forming

The main advantage of cold-forming is that the parts can be customised to suit your needs and the product to be manufactured. In addition, we can say that cold forming of metals is a rather quick operation and perfect for the production of large quantities of profiles.

Finally, it is worth noting that this type of procedure gives the metal greater mechanical strength. In practice, it makes it stronger by increasing the maximum stress it can withstand before reaching the breaking point.
