GALILEO MEGA 2-2410/A Vacuum metallizer

The process is carried out under high vacuum in a closed chamber, in which several boots located under a process roller are used to evaporate aluminium wires. This material condensates on the web, running close by these boots.

Materials Polyester Film :- 8 mic to 65 mic ;BOPP Film :- 8 mic to 50 mic ;CPP Film :- 15 mic to 75 mic ;Paper :- 50 GSM to 175 GSM
Speed 840 max. m/min
Max diameter reel unwinder 1000mm
Max diameter reel rewinder 1000mm
Evapouration Boots Number 27 ; Size 120x35x10mm . PLC, Drives & Control : Siemens S7 With Simoreg Drives for the machine and process control, via supervision PC. The evaporation boats are controlled by a separate cabinet with Eurotherm drives. Machine was installed with Eurotherm Thyristor Unit. We completely replaced those with latest Eurotherm E-power converters along with new HMI in year 2014. These are latest technology by Eurotherm.

Additional information Output : 20 tons per day ( calculated for 12 mic Polyester Film in maximum width ). Min. metallization width 1200mm . Core ID 152mm . Diam of ALU wire 1.6mm. Unwinding tension range /tension capstan unit : 3.5 to 65 Kg / 90 Kg . Diameter of process roller : 500 mm . Additional Cooling System Corema Chilling unit for main process drum ( -20 C) . Max. Absorbed power (approx..) 340 KW . Number of chambers: 3 independent vacuum chambers with independent pumping systems to increase the efficiency of the vacuum. Optical control RF: Controls during metallization process the thickness of aluminium coating through photometric non---contact sensors. The system also controls automatically (via step motor) the deposit of aluminium and the feeding of the wire. Rewinding Unit: Digitally control to ensure an accurate rewinding tension control, via the following five DC motors: Unwinding,Rewinding, process roller (main drive), 2 capstan rollers. Two ceramic plated rollers, 2 bowed spreader rollers, oscillating arm on the rewinder with tension sensing control system. Handling of the rolls: The machine includes a hydraulically driven robotic handling system, manufactured by ICAP Group, for the loading of the jumbo roll, and unloading of the finished rolls. This same system also inserts and extracts the air expanding shafts during the loading and unloading procedure .3 air Shafts are included in the supply . Special Robotic System for Loading & Unloading of rolls.
