Pure aluminium ingots are melted and alloyed with other elements by

            means of master alloy such as iron, silicon, manganese and

            magnesium. The material is analysed and adjusted to ensure the

            correct composition is achieved, then degassed, filtered and

            transfered to casting blocks to form aluminium slabs. The slab ends

            would then be sawn and scalped on both sides by slab saw.

The scalped slab is then placed inside the preheating furnace to be

preheated / homogenized and made ready for the hot rolling process.

The heated slab is hot rolled back and forward several times through

the hot resersing mill to achieve a certain thickness prior to roll

in the 1+2 Stand Tandem Mill.The finished products

are hot rolled coils and plate materials for further process.

            Hot rolled coils are then processed in the Cold Rolling Machine to

            customers' required Thicknesses and further treated in the annealing

            furnaces to achieve the required temper / strength. The Cold Rolling

            Mill machine is equipped with Automatic Gauge Control (AGC) and

            Automatic Flatness Control (AFC) able to produce the closest

            tolerances required meeting the stringent worldwide standards.

Cold Rolled Coil are processed in the Finishing Department for

further process as per customers' requirement such as :

- Tension Leveling for improving the flatness of the material prior to cut to lenght Line for final sheet products.

- Side Trimming for foil stock, slit coil and circle blanks.

- Embossing for embossed coils or sheets and roll forming for roofing products.

Aluminium foil is produced by a process of foil rolling and annealing from cold-rolled coils to reach a target thickness under 0.2mm down to 0.006mm (6 micron). In recent years, a greater variety of aluminium foils has been developed to meet diverse market demands of the consumer product market.

Aluminium foil is placed in the Annealing Furnace by means of heat treatment to reach a specific temper and mechanical properties required by customers.
