The P4 panel bender is a smart manufacturing tool, invented by Guido Salvagnini
in 1977, designed for flexible and automatic production of sequences of panels
starting from punched and cut parts without retooling or operator intervention

Flexible and automatic system
Each P4 is used to produce a wide range of sheet metal
parts, working with universal bending tools featuring
automatic set-up in masked time.
Adaptive technology
Featuring embedded MAC 2.0 technology, the P4
detects in-cycle any variations in the material being
processed and automatically compensates for them.
Precision and repeatability
The oscillating blade operating principle and the exclusive
bending formula along with proprietary thickness
control solutions and thermal compensation make the
panel bender amazingly accurate and responsive.
Versatility and modularity
The loading/unloading devices available allow the P4 to
be configured for working stand-alone or in-line or to
be integrated into a flexible manufacturing cell or an
automated factory.
Efficiency and agility
The P4 panel bender ensures productivity and
efficiency, while operating with different production
strategies, such as JIT, kit or batch-one processing and
medium or small runs.
