What is anti-UV extrusion process: Step by Step Guide 2021


What is extrusion?

Anti-UV extrusion is a thermo mechanical transformation process in which a metal billet reduces in its cross section. When forced to flow through the hole of a die (tool), under the effect of high pressures and temperature. Like toothpaste being expelled from its tube.

The range of profiles that can be extruded from aluminum is virtually unlimited. The process reduces costs, as it eliminates subsequent machining or joining operations. Moreover, it makes it possible to obtain more resistant sections through the proper elimination of fragile joints and a better distribution of metal.

Among the main types of extruded products are solid, tubular and semi-tubular profiles. Its applications are ideal for the civil construction, consumer goods, electrical industry and transport sectors.

Drawing in anti-UV extrusion

It is a transformation process by cold mechanical deformation that allows the reduction of the cross section of a product. Analogous to lamination, the process increases the mechanical properties of the alloy.

Similarly, anti-UV extrusion also includes decreasing dimensional tolerances. Hence, it improves the surface finish and producing gauges that would be more complex to obtain by extrusion. Normally, non-treatable alloys and heat-treatable alloys (in which the function is dimensional accuracy) are there. The industry uses two wire drawing systems:

  • In banks: for bars and tubes of larger diameter;
  • In rotating blocks: for smaller dimensions of rebars and tubes.

Production processes

  • Lamination
  • Stamping
  • Forging
  • Foundry
  • Welding
  • Machining
  • Finishes
  • Recycling

When using aluminum in the construction of parts we are combining several advantages in one material. In addition to its beauty, aluminum provides durability and a low corrosion rate.

Although it has wide use worldwide, there is no single way to work with aluminum. Here at Alumax we work with aluminum extrusion.

What is Aluminum Extrusion?

Extrusion is a process where the aluminum billet undergoes thermo mechanical transformation. It happens through the action of heat and mechanical compression energies. When it flows through the hole of a matrix, also called tool. We can draw an analogy with the toothpaste that expels from the tube. At the end of the process we have an aluminum profile.

What is aluminum anti-UV extrusion for?

The aluminum anti-UV extrusion serves to manufacture profiles, with homogeneous cross section, to be used in the manufacture of various other aluminum products.

A widely used application is in the manufacture of bathroom shower profiles.

At the end of the process, the profile has a constant cross-section and length so, for companies that buy profiles. It becomes easier to work with this standardized material and thus gain scalability in their production stage.

Variety of extruded profiles

Each matrix, or tool, allows you to create a different profile. As we mentioned above, the most used profiles are for making the so-called kit's box. But we can have profiles for windows, stairs, electric bus bars and other infinity of profiles.

For example, if you work in the photovoltaic industry, your demand is for profiles that gear to your industry. So, each type of industry will need a different profile.

Alumax works according to the demand of its customers and offers a wide variety of profiles in its catalog. You can access by clicking here and get to know our tools.

Anti-UV extrusion manufacturers also have the convenience of creating the tool you need, depending on some factors. Get in touch with our sales team and ask all your questions.
Advantages of using an anti-UV extrusion extrude

1 - Storage

As the profiles are homogeneous, it is easier to plan the layout of your storage area and optimize the physical space of your factory.

2 - Price

Orders are in Kg and not in quantity of pieces. So, price when placing an order for extrude products tends to be lower than when purchase is in per unit.

3 - Use of billet

Related to the previous item, as everything fulfills in an automated way, the use of billet is very high. Which results in more pieces produced with the same amount of raw material?

4 - Physical capacities of the material

At the end of the extrusion process, the profile goes to an oven in order to improve its physical properties. Such as hardness and conductivity, so we have even more advantages added to aluminum.

Now that you know what an extrudate is, you know why to use an extrudate. And what are its advantages, you are now able to make the best decision for your industry.


The extrusion of Aluminum Profiles is a production process that allows producing pieces with a constant section, specifically a process by which through a plastic deformation, these parts with a constant section are available, for example plates, pipes, profiles and bars.

In industrial production, the extrusion process has use for metallic materials, such as aluminum, copper, lead or steel. The material to process and transform is usually in a pasty state, or in the form of pellets or powder, and has force by compression and into a shape in order to obtain the desired product, in practice an external form to be used.

Extrusion of plastic materials

If apart from obtaining the anti-UV extrusion process is hollow, the profile of the inner cavity is reproduced by a core which serves to derive precisely the desired section. If you have to do the extrusion of plastic materials, you will have to use the Archimedes screw, which pushes the work material into the head which then allows the final product to come out.

This type of plastic material we insert in the form of powder or pellets and the heat caused by friction with the walls of the extruder determines the final result.

What advantages anti-UV extrusion brings?

Thanks to the extrusion process, the production of aluminum extrusions guarantees most of the applications of the material, in the construction and mechanical sectors. Due to its plastic characteristics, the material is prepares well for this industrial production process.

The application of the process is valid only on materials with plastic physical characteristics in order to guarantee the plastic deformation process underlying the principle.

The function of molding in extrusion

The modeling takes place by compression of the material through a matrix design ad hoc to give the shape to the material being processed. It is essential that the aluminum is in a melt or soft state for the passage of plastic formation to occur.

To be able to extrude the Aluminum Profiles, we must bring the raw material to the ideal temperature, so that the friction force is low to the ideal level to obtain the product. The extrusion process can use different technologies depending on whether the extrusion takes place through the direct method or through the reverse one.


Adoption of it more and more by people, aluminum extrusions represent the majority of semi-finished products, which obtain from aluminum production. Once the anti-UV extrusion aluminum gets through, it comes to the final process.
