Production Flow Chart
1. Melting and Holding Furnaces
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.
2. Hot 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 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. Cut to Length
5. Sheet Coating Printing Line
6. Aluminum Coil Coating Printing Line
Aluminum coil for closure and caps, printed by coil, normally used for vial aluminium seals, aluminium tear off seal, aluminium flip-off vial seals, aluminium closures, pharmaceutical caps, pull-off aluminum cap, aluminum seal cap for injection vial,aluminum cap for injection bottle.
