Vacuum coating machine coated glass is to coat one or more layers of metal, alloy or metal compound film on the surface of the glass to change the optical properties of the glass to meet certain specific requirements. According to the different characteristics of the products, the coated glass can be divided into the following categories: heat reflective glass, low-e glass (Low-E), conductive film glass, etc.

       Heat-reflective glass is generally coated with one or more layers of thin films composed of metals such as chromium, titanium or stainless steel or their compounds, so that the product is rich in color, has an appropriate transmittance for visible light, and has a higher resistance to infrared Reflectivity, high absorption rate of ultraviolet rays, therefore, it is also called solar control glass, mainly used in construction and glass curtain walls;
       Low-emissivity glass is a thin-film product composed of multiple layers of silver, copper, tin and other metals or their compounds coated on the surface of the glass. It has high transmittance to visible light, high reflectivity to infrared, and good heat insulation performance. , Mainly used in construction and vehicles, ships and other vehicles. Due to the poor film strength, they are generally made of hollow glass;
       Conductive film glass is coated with conductive film such as indium tin oxide on the surface of the glass, which can be used for heating, defrosting, defogging of glass and as a liquid crystal display.
       There are many methods for producing coated glass in vacuum coating machines, mainly including vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel.
       Magnetron sputtering vacuum coating machine coated glass can design and manufacture multi-layer complex film system using magnetron sputtering technology, which can plate a variety of colors on the white glass substrate, and the film has good corrosion resistance and wear resistance. One of the most produced and used products. There is a certain gap between the variety and quality of the vacuum coating machine evaporation coating glass and the magnetron sputtering coating machine coating glass, which has been gradually replaced by the vacuum sputtering method. The chemical vapor deposition method is to introduce reaction gas into the float glass production line to decompose on the hot glass surface, and deposit evenly on the glass surface to form coated glass. The method is characterized by low investment in equipment, easy control, low product cost, good chemical stability, and thermal processing. It is currently one of the most promising production methods. The sol-gel method for producing coated glass has a simple process and good stability. The disadvantage is that the product has a high light transmittance and poor decoration. The most commonly used coated glass is heat-reflective glass and low-e glass. Basically, two production methods are used: vacuum magnetron sputtering and chemical vapor deposition.
