Bending processing
Sandrini Metalli performs bending operations on sheets and corrugated sheets by notching, calendering or bending machine.
MAXIFOLD
This process, carried out on a bending machine with a special shaped die, produces a single transversal fold on the trapezoidal sheet with an angle of up to 87°.
NOTCHING
The bending takes place by means of a series of impressions transversal to the corrugated sheet (notches) that produce a series of bends with constant/variable pitch.
CALENDERING
Bending is done by sliding the corrugated sheet through rollers shaped on different planes whose position creates interference.
