thermal evaporationaluminum coatingmetalized film

The R2R web metallizing system is mainly for constantly aluminum metallization on plastic film single side’s coating, like PET, PE substrates. Which is used for high quality packaging material manufacturing. 1. The web coating system adopts advanced round chamber structure, the vacuum chambers contain winding( top chamber) and evaporation chambers (under); winding/unwinding devices are located in the same side of vacuum chamber, which guarantee the system working stably for a long time 2 High efficiency vacuum pumping system for a short vacuum evacuation cycle, improve the productivity efficiently. 3 The web coating system equips with holding pump to ensure energy saving 4 The deposition chamber, winding chamber are equipped with powerful cold trap pumping system, which can effectively drain the vacuum chamber and substrates moisture (temperature-120℃, the total area of the cold trap coil 2 ㎡, which improves the working efficiency of the equipment. 5 The winding system adopts four-motors constant tension control system 6 To ensure the web film’s winding speed adjust is steady, the web coating system equipped with Siemens servo motors and servo speed regulator 7 The high performance SPREADER ROLLERS can adjust the angle according to changes during the coating process to ensure the substrate rolls flatness. 8 The coating roller, from room temperature till -15℃, its cooling and heating system can prevent film’s thermal damage during deposition process. Also can open the spreader roller in vacuum chamber to absorb moisture on the roll surface.
