operations can be performed in one set-up. Work pieces may have re-entrant
profiles and the profile in relation to the center line virtually unrestricted.
parameters and part geometry can be altered quickly, at less cost than other
metal forming techniques. Tooling and production costs are also comparatively
low. Spin forming, often done by hand, is easily automated and an effective
production method for prototypes as well as high quantity production runs
methods of forming round metal parts include hydroforming, stamping, forging
and casting. These other methods generally have a higher fixed cost, but a
lower variable cost than metal spinning. As machinery for commercial
applications has improved, parts are being spun with thicker materials in
excess of 1in (25mm) thick steel. Conventional spinning also wastes a
considerably smaller amount of material than other methods.
can be built using one piece of material to produce parts without seams.
Without seams, a part can withstand higher internal or external pressure
exerted on it. For example: scuba tanks and CO2 cartridges.
disadvantage of metal spinning is that if a crack forms or the object is
dented, it must be scrapped. Repairing the object is not cost-effective.
