Aluminium circle for cookware
The most famous brands of pots and pans have long chosen aluminum to realise their best products.Perhaps not everyone knows that, to produce a pot, it is necessary to start from the production of a circle.
Advantages of Aluminium circle for cookware
The circles are perfectly flat and separated (not stuck), unlike those cooked in the chamber oven after stacking.
The circles are suitable for automated supply systems for the production lines: they do not slow down the line and do not need manual separation.
The better mechanical characteristics of our product make the circles’ roughness much uniform after the mechanical sanding process (used by Customers manufacturing pots/pans lacquered with antisticking or protective coatings).
The flash annealing gives a better metallurgical structure and mechanical characteristics, allowing the metal higher drawing capabilities.
