How they Work
With compressed air only, they are capable of developing great force.
Thanks to the pneumo-hydraulic pressure multiplier incorporated combine the approach and return speed to the workpiece of a pneumatic cylinder with the pushing force of a hydraulic cylinder.
High Flexibility of Applications

Why choose Alfamatic hydropneumatic presses
Productivity
With pneumatically controlled approach and return and hydraulic pressing stroke, reduced cycle times are guaranteed for unparalleled productivity.
Energy saving
The pneumatic / hydraulic separation allows to consume energy only when needed.
Silence
There are no hydraulic power units always in operation, for maximum comfort of use for the operator.
Versatility of use
Many sizes and versions for a press cut to size of application.
Maximum security
All the presses comply with the current strict accident prevention regulations.
They are safe and ready to use.
The heart of the system: the air-hydraulic cylinder
The Alfamatic power units AP and AX are the engine of the OP presses.
They consist of an air cylinder and a built-in hydraulic intensifier. As a result, the full stroke can be subdivided into two separate phases:
- a low pressure fast approach stroke - when the moving ram meets a resistance, at any point during its travel, the power stroke is engaged automatically;
- a power stroke where thrust is increased through the hydropneumatic intensifier.
With 7 sizes and 6 configurations, thrust force from 14 kN to 420 kN, the OP series press line offers high productivity at low costs.

Safety Guards
The CE type protection has the front part with free access, with the operator protected by photoelectric barriers.
The rear and side lexan® barriers then prevent third party access to the work area.
The CA type protection has the front part protected by a pneumatically operated mobile gate.
The rear and side lexan® barriers then prevent third party access to the work area.
The CB type protection has the front part with free access, with the operator protected by the two-hand control.
The rear and side lexan® barriers then prevent third party access to the work area
The Control Panel
For easy and effective control of the work cycle.
The Controls
Air-hydraulic presses can be equipped with electronic systems that monitor, piece by piece, the characteristics of the machining performed.
These systems are based, depending on the model, on pressure/force detection sensors and press rod position. By comparing the sensed values with predetermined parameters, it is possible to determine, accurately, whether the characteristics of the executed part conform to the standard.
Depending on the degree of accuracy, they are available in different configurations:
Check Point System
Functions:
- Displays the expressed and peak force
- Stops the unit when the set force value is reached
Press-Right System
The system uses two transducers:
Display with 640 × 480 resolution in color, full touch, is available for easy use.
Slot for external SD memory.

Main Features
For operating the press and checking the working parameters.
The pneumatic circuit is housed, depending on the press model, into the lower portion of the press, into a pneumatic side cabinet or in the press bed.
In steel Fe 430 B UNI 7070 with ground surface. Equipped with X or T slots (depending on the press model) for mould securing.
They are available in three different configurations, to meet the different application needs and conformations of the piece. All presses comply with the most recent safety regulations.
The press is available with six different structure configurations, to meet the most varied application needs. The bending of the structures, even at the maximum press-force of the presses, is kept within contained values. All surfaces are treated to ensure maximum corrosion resistance.
Depending on the needed power stroke and the required accessories, it is possible to install AP thrust (in line) or AX thrust (parallel structure) units.
