The PCM hydropneumatic press models produced by G.P.A. Italiana use a CM power unit Linear or “U” version now available with extruded anodised aluminium cylinders. The CM cylinders can be used in any position, thanks to the enclosed oil tank with pneumatic spring.
The presses for manual loading and unloading take advantage of a redundant two way circuit monitored with electrical control board.
G.P.A. hydropneumatic presses take advantage of the following features:
- high speed and low air consumption in the approach and return stroke,
-working stroke with smooth application of power using the pressure intensifier hydraulic circuit,
-cylinders with hard anodised aluminium pipes allowing a high level of protection against oxidation and high pneumatic performances,
-reduced consumption of tools and dies, thanks to smooth power application,
-reduced noise level,
-reduced maintenance requirements.
