The glass pvd coating machine is mainly used for the production of coated glass. The coated glass realizes the functions that ordinary glass does not have. The performance is better than that of the original glass, and the price may be more expensive. At present, there are several main production methods of coated glass: one is vacuum evaporation coating; the other is vacuum magnetron sputtering coating; the third is solution gel method; the fourth is powder thermal spraying method.

      Vacuum evaporation glass pvd coating machine, it can be used for glass processing of many products, such as automotive glass, computer display, mobile phone screen and other glass modules. The principle is to use a vacuum glass coating machine to produce coated glass, and the materials that can be coated are different according to the evaporation source used.

       Common evaporation sources for evaporation plating:
        1. The resistance heating evaporation source is simple, economical, stable and reliable, and is widely used. The heating of the resistance in the vacuum chamber melts or vaporizes the coating material, and through a series of processes, the coating material molecules are deposited on the glass to obtain High adhesion and smooth film layer, the evaporation source has the following characteristics: high melting point; stable chemical properties; low saturated vapor pressure, etc.
       2. The electron gun heating evaporation source has a higher energy density than resistance heating, and can evaporate many materials that cannot be evaporated by resistance heating, and can obtain a higher evaporation rate, but its structure is more complex and the price is higher than that of resistance evaporation sources. expensive.
       A special glass pvd coating machine for crystal glass, the evaporation source adopts cathode arc, is equipped with bias power supply or uses ion source, which can provide higher carrying capacity and reduce production cost, and coat golden titanium nitride, wear-resistant film, colorful oxidation Titanium, superhard film, metal decorative film, black titanium carbide, diamond film, etc.
