As for the rolled-formed bellows, the outside and the inside diameters can be created optionally within the extent of elongation of the materials, and can be produced in any size at your request. It is easy to form thick sheet bellows, which can be said to be suitable for the use under high pressure. Also, rolled-formed bellows are the best type for small-quantity production; customers have the advantage of being able to order from one to a few bellows at relatively low cost, and they can be produced in a short time.
