SMELTING

Primary aluminum and sorted aluminum scrap is liquefied in the smelting furnace.

2.

CASTING & ROLLING

The liquid aluminum is poured into a continuous strip. To achieve the desired slug strength, the strip is first hot pressed and then cold pressed.

PUNCHING & HEAT TREATMENT

The desired shapes (standard and customized) are punched from the finished strip. This is followed by a heat treatment in the homogenization ovens.

4.

SURFACE TREATMENT & LOGISTICS

In the final step, the surfaces of the slugs are treated according to customer requirements: blank, blasted or scrubbed. The final steps are packaging and logistics, depending on customer requirements.
