Product Process:
1-1070 Aluminum ingot-Smelting
This stage starts by loading furnaces F1th ,F2th with 30MT each of raw aluminum (alloy AA1070, purity 99,7%
2-Continuous casting and hot-cold rolling
The melt is poured into the strip casting wheel, which rotates at a speed of 6 meters/min. A strip of 220 mm wide by 20 mm thick is formed.
3-Cold Lamination/Rolling
which aloud a maximum tolerance 0,05 mm
4-Stamping/Punching
This stage counts with four stamping presses, In this process we get about 50% of slugs for each Ton of punched strip.
5-Annealing Treatment
With this we obtain a Brinell hardness of 16 a 21 HB.
6-Surface Finish
Surface treatment is sand blasted, vibrated and tumbled
8-Selection and Packing
Boxes are marked with customers information
