Vacuum coating machines are widely used in industry

For vacuum equipment manufacturers, vacuum coating technology has been widely used in energy development, packaging, electronics, optics, surface science and scientific research. The methods used in vacuum coating mainly include evaporation plating, sputtering plating, ion plating, beam deposition plating and molecular beam epitaxy. There is also chemical vapor deposition. If the purpose of vacuum coating is to change the physical and chemical properties of the material surface, this technology is an important part of vacuum surface treatment technology. A brief introduction is now made on several of its main applications.

First of all, in terms of optics, a piece of optical glass or quartz surface can become highly reflective or non-reflective (that is, anti-reflection coating) or reflect in any desired proportion after coating one or several layers of different materials by a doubler light coating machine. Or transmissive material, can also be made into a color filter that absorbs a certain wavelength and transmits another wavelength. The high-reflection film of the vertical single-door coating machine starts from large-diameter astronomical telescopes and various lasers, and reaches the large window coating of new buildings. Anti-reflection coatings are widely used in photography and various lasers, all the way to large window coated glass in new buildings. Anti-reflection coatings are widely used on the lenses of cameras and television cameras.

In terms of components, evaporating nickel-chromium, chromium or cermet in vacuum can make resistors; evaporating aluminum, silicon monoxide, titanium dioxide, etc. on plastic coating machines can make capacitors; evaporating selenium can get toner cartridges for electrostatic copiers, evaporating barium titanate Magnetostrictive sounding elements and the like can be manufactured. The vacuum evaporation coater can also be used to manufacture superconducting films and microbead coatings for inertial confinement reactions. In addition, it can also use the evaporation coating machine to evaporate decorative films on the surface of jewelry, watch casings, textile metal patterns, gold and silver threads, etc., and use the sputtering coating machine to make superhard films on tools and molds.

In electronics, vacuum coating occupies an extremely important position. Succession circuits of all sizes. Conductive film, insulating film and protective film should be used in memory, arithmetic unit, and telling logic elements. A chrome film is used as a mask for the fabrication of circuits. Magnetic tapes, magnetic disks, semiconductor lasers, Josephson devices, and charge-coupled devices (CCDs) also use various thin films. In terms of display devices, video magnetic heads, high-density video tapes, transparent conductive films of flat-panel display devices, light guide films of camera tubes, and aluminum linings of fluorescent screens of display tubes are also prepared by vacuum coating machines.
