The multiplier doubles the pump flow rate and the pump
pressure to provide increased speed and power.
Sacmi recently launched the latest generation of hydraulic
presses in its Imola series. The product line has been fully redesigned and
features cutting-edge technology. The updates to the press’ formal look, which
were developed along with renowned industrial designer Isao Hosoe, have been
accompanied by major technical improvements. The strong points of this new
generation of machines can be summed up as follows:
- Accumulators provide the acceleration to ensure maximum productivity
under all working conditions.
- A status indicator provides clear information on the current working
status of the machine.
- An SPE ejector quickly and
precisely allows filling in the larger-sized presses to be controlled with the
same level of quality and repeatability as the small sizes.
- A variable displacement pump control unit supplies the propulsion
that allows high output rates without wasting any energy, thanks to the
optimization of the hydraulic circuit.
- A multiplier doubles the pump flow rate, which increases the cycle
execution speed even with very thick sizes. The multiplier also doubles pump
pressure, thus increasing pressing power for the production of very large
- Proportional hydraulics allow for fully automatic control of the
press, ensuring precision and repeatability even with high output rates.
- The profibus ensures outstanding
control system processing speeds, enabling the attainment of precision and
repeatability even where productivity is very high.
The main cylinder is fixed on the main frame, and the pressing piston slides
inside it. This configuration ensures optimal rigidity of the various
structural parts and, therefore, uniform distribution of the pressing load
under all working conditions. The hydraulic control unit is connected directly
to the cylinder itself for maximum speed and precise control of all of the
forming parameters. The new range is also equipped with the latest generation
of control software, which provides automatic self-tuning to maximize
productivity performance without affecting the quality of the final product.

SIDEBAR: Multi-Size Upper Base
The new multi-size upper base (MUB) patented
by Sacmi Molds & Dies is an advanced version of the SFS mold and offers
enhanced performance in terms of both versatility and ease of management. A
complement to the lower universal base, the MUB retains the classic two-part
structure (hydraulic plate and ejector block) but offers innovative
The base supports both a range of sizes and a number of outfeed cavities thanks
to the universal ejector block, which can function as an upper plate and allows
the pressing mode to be changed. From upper forming, the die can quickly be
transformed into a mirror or entering punch die. Considerable investment
savings are available since the required number of bases becomes a function of
the number of presses and no longer a function of the quantity and type of
further advantage lies in the rapidity with which the above changes can be
completed. Both ejector block and hydraulic plate are equipped with a system of
permanent magnets that allows rapid locking and replacement of the punches and
the upper die box. The permanent magnet locking system reduces press setup
times without losing any of the safety or reliability of traditional mechanical
