The RFA – 680 is used for manufacturing both small and large rollers using polyurethane. A ribbon of liquid urethane is applied to a rotating roller and moved across the cylindrical surface.
The method is somewhat similar to turning, but the material is applied instead of being removed. It is possible to build layers to different thicknesses for subsequent machining to accurate dimensions.
