Nutberry Bellows are manufactured by the precision roll formed method, from stainless steel or high nickel alloy material.
This method of manufacturing was originally introduced in the USA and at that time the process was very labour and skill intensive and therefore expensive. However, with the introduction of CNC forming, this process has been considerably improved and thus reducing the cost of production of the bellows and maintaining the superior performance we can now offer.
Nutberry bellows are manufactured using CNC controlled forming machines. The benefit of this manufacturing method is that it produces uniformed work hardening at both the root and crest of the convolutions, compared to traditional hydro-forming methods where metal can be thinned when forming the convolutions.
Material is taken in its sheet form, cut, rolled and welded along the seam to produce a tube. All welds are checked for leaks and integrity by mass spectrometer testing. The tube is then precision form rolled into convolutions with CNC rolling machines to required specifications.
Nutberry can manufacture up to six ply bellows with the material thickness ranging from 0.13mm to 0.75mm. Bore sizes range from 16mm to 200mm.
