Our onsite facilities house a range of state of the art conversion machinery including a range of presses, CNC machines, slitting machines and log cutters, enabling us to take these rolls or sheets and cut them into washers of any shape and in most sizes.

What are Food Quality Silicone Sponge Rubber Washers?
