Process

The choice of the right raw material is one of the keys to a high quality finished product.

The solid aluminium is transformed into molten aluminium in high capacity oil fired melting furnaces.

Casting of molten aluminium is done manually into hydraulically operated water cooled moulds by very experienced and skilled labour.

A seven gear high capacity hot roll mill is used to hot roll the castings into desired thickness for preparation of cold mill operation.

A four high cold roll mill is used to prepare the aluminium into desired thickness per customer’s requirements of slugs or circles.

High-speed presses varying from 30 to 50 tons are used to punch the slugs from the finished aluminum strip. This slug production process generates slugs of very high dimensional accuracy.

Once punched, the slugs must go through an annealing process. High efficiency electric ovens are used for this process.

The slug surface must be roughened up to meet the customer process requirements. This is done with a tumbling operation. Afterward, the slugs are packaged using a manual process.
