Output: 20 tons per day, calculated for 12mic Polyester film in maximum width
Minimum metallization width: 1200mm
Core ID: 152mm
Diameter of ALU wire 1.6mm
Unwinding tension range/tension capstan unit: 3.5 to 65kg/90kg
Diameter of process roller: 500mm
Additional cooling system Corema chilling unit for main process drum -20c
Maximum absorbed power approximately: 340kw
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
Rewind unit: digitally control to ensure an accurate rewinding tension control, via the following five DC motors
Unwind rewind, 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: 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

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 and unloading of rolls
