Company:
|
Ernesto Parmigiani
|
|
In 1927
Mr.Ernesto Parmigiani started his company manufacturing equipment and
the tanks for the chemical industry.
In a few
years, the big growth of the chemical industry increased the market demand
of metalforming machines especially employed in the tank head and supporting
the
plants manufacturing industry; (plate bending rolls, section bending
machines, flanging and dishing equipments).

Ernesto
Parmigiani and his team in 1934
|
|
For
this
reason, Mr. Parmigiani started a company which has been and still is a world leader of
manufacturing
metalforming
machines.
The name
“PARMIGIANI” today still means KNOW HOW, RELIABILITY and TRADITION.

1936: Section bending machine Mercury |
|
In
the 30’s the
first section bending machine known as "Mercury" is introduced in the market. This
machine would become one of the most sold section bending machines.
In the 50’s
Parmigiani designed the first self-contained electro-hydraulic machine. This
solution became immediately important for costs reduction, increased
efficiency and machine safety. |
|
 |
|
In
the late 50’s also the 3 rolls plate bending rolls have been definitively
refined introducing very avant-garde technologically advanced solutions such as the
independent adjustment of the lower rolls regulation (double
pinch design
for prebending
both edges without the need
to remove, turn and re-insert the plate)
and the 3 roll drive technology, for optimal plate feeding. |
|
1952:
Parmigiani 3-roll plate bending rolls 3100 x 25 (10' x 1") , double
pinch type, with 3 driven rolls and with intechangeable (small diameter) top
roll.
|
|
In 1964
PARMIGIANI manufactures the world largest plate bending roll for the Aircraft
industries with a useful length of 10
meters
(33').
|
|
 |
|
In the early
60’s one of the world largest Pressure Vessels Manufacturer committed to Parmigiani a 4600
x 130mm
(15' x 6") plate
rolling machine type PCO, with fully hydraulic rolls-adjustment and with top
roll bending force of 2400 metric tons.
In the 70’s
PARMIGIANI introduces high efficiency drive on the 3 and 4-roll plate bending rolls
via
hydraulic
motors and
planetary
reduction units
directly coupled to each driven rolls.
In
the middle 80’s the
rolls
electronic parallelism control
(syncro)
becomes a
standard on each PARMIGIANI plate bending rolls. |
|
 |
|
In the 90’s
PARMIGIANI manufactures a Flanging machine with fully electronically and
infinitely variabile speed controls.
The range of production of
the PLANET line of section/angle
bending machines has been expanded to include larger and more heavy-duty
models for bending beams up to 1000mm
(40") and pipes with
O.D. up to 609 mm (24").
In 1998
PARMIGIANI installs successfully a huge (“THE WORLD LARGEST”) 3 rolls
CNC Plate Bending Machine for Aircraft industry, with 12
meters
(40') working length.
