Glass coating machine is mainly used for the production of coated glass. After coating processing, the glass achieves functions that ordinary glass does not have, with better performance compared to the original glass, and the price may also be higher. There are several main production methods for coated glass currently: first, vacuum evaporation coating; Vacuum Magnetron sputtering coating; Solution gel method; The fourth method is powder thermal spraying.

Vacuum evaporation glass coating machine can be used for glass processing of many products, such as automotive glass, computer display screens, mobile phone screens, and other glass modules. The principle is to use a vacuum glass coating machine to produce coated glass, and the materials that can be plated vary depending on 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. Heating the resistance in a 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 a high adhesion and smooth film layer. This evaporation source has the following characteristics: high melting point; Stable chemical performance; 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 achieve higher evaporation rates. However, compared to resistance evaporation sources, it has a more complex structure and is more expensive.

A specialized glass coating machine for crystal glass, which uses a cathode arc, is equipped with a bias power supply, or uses an ion source to provide higher load-bearing capacity and reduce production costs. It can plating gold titanium nitride, wear-resistant film, colorful titanium oxide, superhard film, metal decorative film, black titanium carbide, diamond film, etc.
