Aluminium extrusion is a process that was developed during the Industrial Revolution and has become one of the mainstays in all forms of industry from architecture to the manufacture of cars.

The extrusion process begins with a small ingot of raw or mill finish aluminium being slowly heated until it becomes malleable but does not turn into a liquid. It is then transferred to a table and machinery where it is then forced through a pre-formed die cast mould at high pressure. The molten aluminium is rammed with a power press.

The extruded shape can be extremely complex to create fixtures and fittings for a variety of applications such as shelving connectors, radiator grilles and other components. The extrusion is then manoeuvred into the correct alignment before being quenched in cold water to harden it. It is a delicate operation that needs an experienced hand and eye in addition to the latest technology that helps to guage the correct temperatures required at every stage.

The extrusion then has to be cured in an oven at a temperature of up to 400 degrees Celsius for around twenty minutes. Even though the aluminium extrusions are still hot, with a minimum of cooling they can be assembled, packed and transported to their destination. Fast turn arounds make aluminium extrusions an ideal choice for a variety of single one off components or batches of fabrications. Orders can be processed within very short time frames ensuring that designs are seen through to conclusion with a minimum of delay.

Aluminium extrusions are extremely cost effective due to their long lasting properties. Extrusions provide endless opportunities for manufacturers to maximise the return on their investments as the product can be processed and delivered quickly.

Designs can be turned into manufactured products at a cost effective price. Aluminium is one of the most economic metals with great flexibility for a range of different products.
