There are many kinds of vacuum equipment, among which the pvd coating machines is just one of the vacuum equipment. Generally speaking, vacuum equipment, everyone's first reaction is that it is a pvd coating machines, but it is not. Vacuum equipment is not only a coating machine, but also other fields. For the equipment, the following Huicheng vacuum editor has sorted out some equipment related to vacuum equipment for everyone, hoping to be helpful to everyone:

Vacuum equipment products can be divided into five categories:
        (1) Vacuum obtaining equipment-a device that generates, improves or maintains vacuum. Including all kinds of vacuum pumps and vacuum units for coarse, low, medium, high and super high. A. Mechanical vacuum pumps: rotary vane pumps, reciprocating pumps, slide valve pumps, Roots pumps, molecular pumps and liquid ring pumps, etc. B. Vapor flow vacuum pump: water vapor jet pump, oil booster pump and oil diffusion pump, etc. C. Gas capture vacuum pump: titanium sputtering ion pump, cryopump, molecular sieve adsorption pump and zirconium aluminum suction pump, etc. D. Vacuum unit: that is, various units composed of components such as generating vacuum, measuring vacuum and controlling vacuum.
        (2) Vacuum application equipment ~ various equipment applied in a vacuum environment (gas state below one atmospheric pressure)
        A. Vacuum coating machine: evaporation coating machine, magnetron sputtering coating machine, ion coating machine and plasma chemical deposition device, etc.
        B. Vacuum smelting furnace: resistance furnace, electron beam furnace, electric arc furnace, induction furnace and single crystal furnace, etc.
        C. Vacuum heat treatment furnace: quenching furnace, tempering furnace, annealing furnace, carburizing furnace, nitriding furnace and metalizing furnace, etc. D. Other vacuum equipment: freeze drying equipment, distillation equipment, purification equipment, impregnation equipment, fruit and vegetable preservation equipment, Transportation equipment, space simulation equipment, packaging machines and molten steel degassing devices, etc.
        (3) Vacuum measuring instrument—an instrument for measuring the pressure of gases and vapors below one atmospheric pressure.
        A. Low vacuum gauge (measuring range 105--102Pa).
        B. Medium vacuum gauge (measuring range l02-l0-1Pa)
        C. High vacuum gauge (measuring range l0-1-10-5Pa).
        D. Ultra-high vacuum gauge (measuring range < 10-5Pa).
        (4) Vacuum leak detector—an instrument that detects the position or leak rate of vacuum system or component leaks. Including high frequency spark leak detector, halogen leak detector and helium mass spectrometer leak detector etc.
        (5) Vacuum valve-in the vacuum system, it is a component used to adjust the flow rate, cut off or connect the pipeline. Including flapper valves, flapper valves, solenoid valves, solenoid belt bleed valves, diaphragm valves and regulating valves, etc.

Principle introduction of pvd coating machines:
        The pvd coating machines is mainly a coating equipment carried out under a relatively high vacuum degree. Its coating technology specifically includes many types, such as vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, ion beam sputtering, etc. The daily vacuum coating machine is applied to different fields, we will take different names, such as applied optics, then we will become an optical pvd coating machines, applied to flexible materials, then we will become a winding vacuum coating machine, and auto parts pvd coating machines , Hard coating vacuum coating machine, decorative vacuum coating machine, etc. Vacuum coating machine has a wide range of applications, often used in electronic products, architectural hardware, watchmaking, large workpieces, auto parts, parts, and daily application products in life, etc., so pvd coating machines are in demand in the market It is also very large.
