Extruding Aluminum for More Than 20 Years

Extruding aluminum is a process that requires the precise following of several important steps. To explain it briefly, the heated aluminum billet is pushed through a pre-designed die under pressure with a ram. You can any standard or custom shape and diameter to meet your precise aluminum extrusion requirements.

Preheating the Billets

First, the size of the billet is determined according to the order specifications. Then the billets are moved to a heating tunnel where they are heated up to the required weldability temperature. The temperature you need depends on the type of extrusion you choose and the type of alloy you work with.

The Extrusion Process

After the billet is heated, a lubricant is applied to it. The billets and dies meeting customers’ specifications are placed in line. The main feature of extruding aluminum successfully is maintaining the same temperature throughout the process. With a ram, billets are pushed through dies.

Cooling

Once again, this part of aluminum extruding varies for different manufacturers and the results the customers are looking for. The extruded profiles can be cooled with air or water. Cooling precedes stretching so the cooling methods should be discussed with project managers in advance.

Stretching

The cooled profiles are then stretched. This way, the manufacturer ensures they are straight and ready to be cut to the requested lengths.

Final Hardening

Aluminum products are heated up one more time up to four hours to be hardened even further. At the final stage of extruding aluminum, aging techniques and chosen finishes are applied.
