Bell mouths spin forming/bending results

Bell mouths (spin-formed)


Inside diameter φ3000mm
Sheet thickness 18mm
Material SUS Clad
We are capable of manufacturing bell mouths through a special bending process called spin-forming.
Unlike press-forming, spin-forming creates bell mouths of any shape without using any dies or wooden patterns.
Although there are limits on the sheet thickness (Max 28t) and the diameter (Max φ4500), this method does not require dies for creating bell mouths, which results in reduced manufacturing costs and shortened lead-times.
This bending method is very productive for creating prototypes and single parts as well.
We are confident that our know-how regarding bell mouth manufacturing and the resulting quality of our products are unrivaled.
