The new development of the vacuum coating machine

The development of vacuum coating machine is quite rapidly, with the improvement of productivity, production cost is reduced greatly, has paved the way for the widespread use of vacuum coating products. Winding type vacuum coating machine, for example, when just development can be plated film base material width is 150 mm, 2253 mm. Base material of the drum maximum diameter is 1000 mm, maximum wind speed of 750 m/min. Automatic loading and unloading of the semi continuous winding type vacuum coating machine coating time accounted for 75% of the whole cycle, auxiliary operation time accounted for only 25%. More efficient from the atmosphere to the atmospheric coiling vacuum coating machine has been sold in 1977. With the progress of measuring technology, control technology and the application of electronic computers, coiling vacuum coating machine is developing toward the direction of the high automation and high reliability.
Vacuum coating machine vacuum coating machine to sedimentary thickness of coating layer range 0.01 0.2 & mu; M, can choose in this range, and some can also be plated multilayer film, meet various needs. Japanese patents put forward two different sedimentary evaporation coating material winding type device. The device of the vacuum chamber is divided into the upper chamber, lower left ventricular and right. Evaporation, two groups of evaporation source material coating deposition on the plastic film, respectively, in the side of the plastic film is no evaporation in glow discharge generator. Generator of glow discharge gas can prevent plastic wrinkling. Can use the device in a very thin plastic film plating without crease of multilayer film, for making tape and thin film solar cells, etc.
