Alumentary: Cold Forming of Aluminum

Aluminum is one of the key materials in our production, but the material only reaches its full potential when processed using the right technology. Cold forming is an important method in this regard.

In cold forming, aluminum is plastically deformed below its recrystallization temperature. This means that the material is shaped under high forces without being heated beforehand.

One of the greatest advantages of this method lies in the high precision and surface quality of the components, as they are produced directly from the forming process with tight tolerances. The work hardening of the aluminum during cold forming increases the material’s strength—a property that is a key factor in the mass production of fasteners. This allows us to produce cost-effectively while maintaining consistent quality.

However, the advantages of cold forming aluminum are offset by a few challenges. With severe and repeated cold forming, the material’s ductility decreases, meaning the risk of cracking increases. In addition, elastic springback can lead to dimensional deviations, which must be taken into account during process design.

However, with the right technical expertise and process control, we at ESKA are able to overcome these challenges and thus manufacture precise, high-performance components.

After all, aluminum has great potential—but only if you know how to shape it properly.
