Step 01 - Raw Material Selection
The choice of the right raw material is one of the keys to a high quality finished product.
Step 02 - Aluminium Melting
The solid aluminium is transformed into molten aluminium in high capacity oil fired melting furnaces.
Step 03 - Slab Casting
Casting of molten aluminium is done manually into hydraulically operated water cooled moulds by very experienced and skilled labour.
Step 04 - Hot Mill
A seven gear high capacity hot roll mill is used to hot roll the castings into desired thickness for preparation of cold mill operation.
Step 05 - Cold Mill
A four high cold roll mill is used to prepare the aluminium into desired thickness per customer’s requirements of slugs or circles.
Step 06 - Punching
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.
Step 07 - Annealing
Once punched, the slugs must go through an annealing process. High efficiency electric ovens are used for this process.
Step 08 - Surface Treatment/Packaging
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.
