Hydraulic System

• The assembled solid platen is composed of two Fc 430 steel plates welded together.
• The welding is realized on assembling templates with presses to grant the platen flatness
• Already in this assembling phase.
• Between the two steel plates there are drawn steel pieces inserted and welded to make the
• Circuit which the heating medium flows in.
• At the end of the working, the tight joint is tested by 5 bar pressure.
• To avoid residual stresses due to the welding, the platen is treated with the stretchin process.
• The casting phase before the final check is the treatment of the surfaces of the platen in two
• Different operation

1. The rough-shaping to eliminate the last differences on the platen flatness
2. Working surface finishing with special scrapping millers for good roughness; millers
3. Mounted on CNC tool-machines to grant the precision of the flatness necessary for the best Working quality.

• Between the press structure and the heating platen is positioned a thermal insulating sheet.

The hydraulic power pack is composed of double stage pumps and motors which are noise free and self-lubricating type for rotational parts. These pumps are designed to get high delivery and low pressure at the closing stage and low delivery and high pressure at the opening stage.

• The unit is fitted with the following control and safety valves.
• Relief valve for the closing, which will cut off the oil delivery after closing. This will reduce power consumption and less oil heating.
• Relief valve for the opening.
• Temperature gauges for monitoring press plate temperature.
• Pressure valve for pressure release.
• Pressure gauges for pressure monitoring.
• Solenoid for quick oil discharge.
• Oil filters for unwanted particles scrutiny.
