This is a metal roll for film forming and lamination.
It is made by outer surface of thin metal roll, roll shaft, and air between a shaft and a outer metal roll.
Thickness of this outer metal roll is around 0.2 to 0.4mm.
When you push its roll surface, you can feel that the pressed area sinks a little.
Pressure inside this roll is 0.3Mpa max and is adjustable.
So we can set different inner pressure exactly as we change and try several rubber rolls to get the best nipping.
Yet this outer metal roll is smooth and does not damage films.
