In the vast world of metalworking, one of the many possible operations stands out for its precision, its versatility and the impeccable results it allows to obtain: it is cold extrusion. This process allows to obtain customized solutions for metal components for the automotive and agricultural machinery industry, satisfying both the requirements of strength and stability as well as the requirements of customization.

What is cold extrusion of metals and how it happens

Cold extrusion is a metal processing technique that allows to obtain the metal forming through the use of a matrix, without resorting to heat sources. During cold extrusion, the metal is pushed through the matrix with a compressive force, so that it assumes the desired shape.

In detail, the metal is loaded into the extrusion machine, inside which it is compressed and pushed through the matrix with a controlled pressure. As mentioned above, the matrix is designed to give the metal the final shape that needs to be obtained; this can be both a complex cross-section and a specific shape, ready to go into operation. During the cold extrusion process, the chosen metal undergoes a plastic deformation that allows to maintain its properties and improve its functionality.

Advantages of cold extrusion for metal components

Obtaining components for automotive and agricultural machinery through a cold extrusion process brings with it a series of advantages of both technical and economic nature; among them, the ability to produce components with extreme precision and a surface finish of a much higher quality than other hot working methods. This is particularly relevant in the areas mentioned above, where product quality and reliability is essential to contribute to the final safety of the vehicle.

Cold extrusion also allows to obtain parts with superior mechanical properties such as increased strength and durability. This is due to the inherent nature of the extrusion process, which subjects the metal to plastic deformation at “room hardening”, thus maintaining its original mechanical properties intact. Flexibility is also one of the advantages of cold extrusion: this type of metal processing allows to work with a wide range of raw materials including aluminium, steel, brass and special alloys: an extra gear to respond exactly to customer requests!

In addition to the benefits of a purely technical nature, cold extrusion also offers significant economic advantages: this process is in fact known for its energy efficiency and low production costs, as it does not require the use of systems that generate heat as is the case in hot metal processing. This results in lower energy consumption and significantly lower operating costs, which allow you to calm the final price.

Last but not least, there is process automation: cold extrusion is a highly automated process, which makes it a highly efficient production and allows to minimize the risk of errors and defects during the production of metal components.

Which final products can be obtained by cold extrusion?

But, concretely, for which requests in Prodotti EBI we use cold extrusion of metals? There are multiple components, for example inside a car, which can be obtained by cold extrusion. These include the following:

1. Anti-roll bars.
   Essential components for vehicle roll control during bends, they are often made by cold extrusion of aluminium alloys or high strength steel to ensure lightness and rigidity at the same time.
2. Structural profiles for frame.
   Cold extruded profiles are widely used because they allow for lightweight but robust components; these profiles made with cold extrusion can protect passengers and mechanical parts of the vehicle.
3. Guides for car windows.
   These are fundamental elements in the mechanisms of opening and closing car windows; they can be produced by cold extrusion of aluminium alloys that offer corrosion resistance and ease of processing.
4. Door pillars.
   Door pillars provide structural support for car doors and contribute to passenger safety in the event of a collision.
5. Seat guides.
   Seat guides are components that allow adjustable movement of the front and rear seats inside the passenger compartment of the car. They can be made by cold extrusion of aluminium alloys or steel, to obtain strength and durability.
