Hot hydraulic press NPC DIGIT 6/100 (8’x4’) – 120T
|Top& bottom fabricated steel platens||
|max total thrust||
|clearance between platens approx.||
Fe 430 steel beams welded together;
Locating surfaces are CNC tool machined
Double rack and pinion system (both length and crosswise) to grant a perfect platens’ parallelism when the mobile one is moving up/downward.
Between the press structure and the heating platen there is a sheet of insulating material.
The bottom platen is hooked to the press structure ; the upper platen is hooked to the platens supporting structure
Platens covered by a 10/10 Aluminium sheet
The platens are connected by hoses (types according to the used heating medium) to the manifold (even if the press is sold without heating plant).
Hydraulic power unit composed by a double stage pump and a motor which are submersed in the hydraulic oil for a less noisiness and a better lubrication of the rotating parts.
60 l/min closing stage (high delivery at low pressure)
2,6 l/min thrusting stage (low delivery at high pressure)
3 Hp electric motor
Unit fitted with the following control and safety valves which are located in a group over the hydraulic oil tank lid:
– relief valve for the closing stage. After the platen closing it cuts off the oil delivery; lower absorbed power and less hydraulic oil heating up;
– relief valve for the thrusting stage. It avoids over pressures in the circuit;
– keeping pressure valve;
– valve to release the pressure smoothly;
– solenoid valve to discharge the oil quickly;
– filters both in the inlet and outlet to avoid foreign bodies from circulating in the circuit.
Thrusting cylinders are made of steel for mechanical application and according to Ormamacchine design.
Rams are thickness chromium plated; they slide over guiding bushings made of antifriction material and are constantly lubricated by the hydraulic oil.
All hydraulic components are engineered and tested at higher conditions than those of normal working for a safer and longer working life.
The main control panel includes:
Touch screen keyboard for:
Heating system with Electrical Heater with OIL heating fluid with max 130°C
System complete with : circulating pump, open expansion tank, piping from the boiler to the press, air leaking valves, control board, control and safety instruments.
