Press Structure
The press structure is made of fe 430 beams assembled and welded together.
The structure of both the fixed and movable platen is made of fe 430 beams assembled and welded together.
The press is equipped with rack and pinion guide system to ensure a perfectly parallel movement during the closing/opening of the platens.

Assembled platens with coil and aluminium covering
Maximum oil Temperature 120°C
Maximum specific working thrust 3-5 kg/cm²
Maximum thrust of heating Fluid: 2 bar
Our assembled platens with coil + aluminum covering are completely built in our metal workshop. Each coil, before being installed in the platen, is submitted to a strict leak test.
A 3 mm calibrated sheet is placed on top of the coil.
The platens are covered with aluminum sheet, that gives the platens an excellent surface finish and optimal heat propagation.

Hydraulic  system
• the hydraulic system consists of a double stage unit with submerged pump to reduce the noise and lubricate the rotating parts.
• quick closing/opening pump (high delivery- low pressure 35 L/min), pressing pump (low delivery-high pressure 1.6 L/min).
• 2 hp electric engine
• the hydraulic unit is equipped with the following control/safety valves, installed on the tank:
- maximum pressure valve: prevents to have too high pressure in the hydraulic
  system in case of electric or electronic control fault
- pressure holding valve (retaining valve)
- low releasing pressure valve (pre-releasing valve). It avoids dangerous ram hits inside
  the system
- oil release control magnet

Control panel and Electrical system

The pressing parameters can be managed from the control board that is equipped with the following switches/ gauges:

- temperature gauge to control platens temperature
- Pressure regulating gauges and automatic pressure recovery system
- general on/off switch
- two hand safety switches to close the press
- Timer for automatic opening with its own switch activates the automatic 
  or manual opening of the platens after the work cycle.
- off/on switch for heating resistance that switches the boiler off when the 
  set temperature is reached to restore the temperature, if there is any
  temperature decrease, in order to save power consumption.
- heating pump on/off switch

Safety systems
- Timed bimanual control for press closing
- Safety rope on the four sides of the press
- Platen locking device for maintenance
- Protection carter for the pinion/rack units
- Safety stickers and warnings
- Use and maintenance manual
- the press is compliant with CE standards
