2010 ETAT DE LA MACHINE:
The ORMA MACCHINE Membrane Press PM/CA/AIR is a machine designed to coat shaped panels either with thermoplastic PVC foils or VENEER by automatic pressing cycle. The 3D distortion of the coating material is enhanced by the utmost operational versatility and simplicity of this machine.
Press structure in Fe 430 steel beams welded together.
Locating surfaces are tool machined.
Platen parallelism granted by rack coupling and conic mechanism on the four sides.
Safety grids on machine sides.
Drilled solid steel upper platen heated by thermal oil.
20 mm high perimeter flange made of galvanized steel with special O-ring silicon seal in order to ensure the perfect pressure tightness.
Lower movable platen made of welded steel beams and sheets.
Vacuum and air pressure circuits integrated in the platens.
Machine fitted with a powerful vacuum system and pressurized air tanks which allow an instant and constant pressure delivery into the working chamber.
500 lit. air tank accumulation tank.
Vacuum pump delivery: 70 m3/h (max. vacuum 0.5 mbar = 99.95%)
Heat exchanger for air heating.
Hydraulic unit with double pump and with motor in oil bath for less noise and better lubrication.
High capacity low pressure pump for quick closing and low capacity high pressure pump for slow getting into pressure.
Thrusting pistons are steel manufactured according to an exclusive ORMA machine design. Thickness chromed shafts to increase their hardness so to grant their durability, are sliding on bushings made out of anti-friction material and constantly lubricated by the same oil used for the hydraulic plant.
Free standing electric cabinet (reading desk type) complete with all electrical and electronic components; control and settings through digital keyboard with graphic display for data visualization; independent digital setting of every function of the press; proportional electronic control of the hydraulic pressure in connection with the air pressure in the pressurized chamber;
PLC controlled functioning; hardware SIEMENS, software by Orma machine.
Memory program system against tampering of content; hardware complete of status indications and automatic graphic signalling of possible malfunctions.
The system software controls the following functions:
Short circuit control
Functioning anomalie graphic signalling on display
Electric heater for thermal oil to control the temperature of the top platen.
