Specifications Description The production of superior quality bellows can be broken dwon into two main stages, manufacturing high quality tubing and forming corrugations. The tubing comes from a time tested method of drawing and pressing a wide range of high quality material. The finished bellows are manufactured through various combinations of hydraulic and mechanical forming.
