Aluminium extrusion is a mechanical process in which aluminium billets are converted into profiles of a set cross-section. The raw material is heated to the required temperature for the production process, and then a high-power press is pressed through a matrix of hardened steel with a disbanded cavity corresponding to the shape of the profile you want to get. This process is followed by stretching, cutting and hardening operations necessary to obtain the mechanical properties of the final product.
The main stages of the aluminium extrusion process:
- aluminium billets are heated to the required temperature for the production process;
- billets are transported to a hollow cylinder called a container, at the end of which a matrix is inserted;
- the billet, under the influence of the force of the piston, moves through the matrix cavity, disbanding the profile;
- the resulting profile is cut to the length desired by the customer and transported to the ageing furnace. At controlled temperature, the required profile hardness is achieved;
- subsequently, profiles are packed in solid, transportable packaging.
