A quality-conscious process for the best end product

The quality approach controls the entire process at Kubal from inspection of the incoming raw materials, through care of the pots, to the final end products, which are delivered to customers by road, rail and sea.

The first quality inspection of the metal is performed in the pot before it is tapped. Further samples are taken after tapping, and analysed in an optical spectrometer, which reveals any traces of foreign materials, such as iron. The objective is to produce as pure a metal as possible.

The next stop is the holding furnaces, where the metal is prepared for use in various different applications. With suitable alloying elements, aluminium can be given an extremely wide range of properties, tailored exactly to suit the needs of the final product and in accordance with customer specifications.

After pouring, the molten metal solidifies into slabs or extrusion billets. This is followed by further processing, inspection and loading for delivery.

Substantial investments have been made in the cast shop in recent years. One of the most recent investments is the Hot Top Air Slip, which is a modern casting method that improves the quality of the extrusion billets, enabling extrusion process speeds to be increased. Another recent investment is a homogeneous furnace construction for longer billets. With these investment´s Kubal has taken another step in the devolpment to meet the customer´s increasing demands on slabs and extrusion billets.

In 1994, Kubal received proof of its successful quality work through receipt of ISO 9001 certification. This is a quality approval which guarantees that the company meets all aspects of stringently specified performance requirements. It also establishes a standard that acts as a guarantee for the future.
