Aluminium Extrusions

The extrusion technique offers virtually unlimited design possibilities. Together with the ability to build in and integrate features and functions that save both work and money, this makes aluminium extrusions the ideal construction material.

Extrusion

Extrusion means heating an ingot of aluminium and pressing it under high pressure through a tool with a cross-section corresponding to the finished extrusion. The speed depends on the composition of the alloy and the complexity of the pattern of the tool. The extrusions are drawn out onto a receiving table, stacked and allowed to cool. They are then tempered and cut. Any fabrication or surface finishing is then carried out.

HAP have three presses with press force from 1.200 tonnes up to 7.000 tonnes and with capacities from 80 g/m up to 30 kg/m. Extrusion width up to 520 mm.

Strängpressning

Extrusion process

Strängpressning

A heated aluminium billet is pressed through a die the opening of which corresponds to the cross-section of the extrusion.

Strängpressning

The extrusion press speed depends on the alloy and the compexity of the die´s opening.

Strängpressning

When the extrusion leaves the press it moves onto a table where it is cooled with air or water depending on it´s size, shape, alloy and required properties.

HAP Presses

HAP have three presses with press force from 1.200 tonnes up to 7.000 tonnes and with capacities from 80 g/m up to 30 kg/m. Extrusion width up to 520 mm.

HAP’s 7000 tonnes extrusion press is one of the biggest of its kind in Europe.

Types of extrusions

There are two types of extrusions:
Hollow extrusions
