The system is designed to sputter the three-layer or four-layer film for the glass in the vacuum chamber based on the magnetron sputtering technique. It is a kind of multifunctional system that can be used to plating various single-layer film, reaction film & complex film. In the whole plating process, it is controlled by the PLC device. As it has many advantages such as fine film, firm adhesion, good optic performance, and high stability etc. It is an ideal vacuum plating equipment for plating high-class curtain wall glass & large glass with multiple film systems & different colors.
