Production Step :

1. Melting and Holding Furnace



Pure aluminum 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 aluminum slabs. The slab ends would then be sawn and scalped on both sides by slab saw.



2. Holding Rolling Mesta 1+2 Stands Tandem Mill


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.



3. Cold Rolling Davy Machine

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.



4. Punch to Circle


Hot rolled quality or cold rolled quality of aluminum strip will be sent by conveyor to the Punching machine which gets punching head with different mold to produce various kinds  diameter discs as customer’s requirement. 



5. Annealing Furnace

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