When thickness is below 0.2mm, the material is also called stainless foil. 0.127mm stainless foil production is very hard, there are some key processes.
- raw material choice
We can only choose POSCO’s master reel or other sources. But the yield is very low, especially the thickness of less than 0.1mm. - 3 rolling +3 annealing processes
The production of stainless steel foil is very slow, if the production is too fast, the foil will break, and the cost is very high. - Only 20 rolled Senzimier machinery
To produce stainless steel foil. We can only use machines of this brand.
