There are many kinds of vacuum equipment, among which vacuum coating machine is only one kind of vacuum equipment. Generally speaking, vacuum equipment is thought to be a vacuum coating machine at first, but it is not. Vacuum equipment is not only a coating machine, but also equipment in other fields. The following is a small series of vacuum equipment to sort out some equipment related to vacuum equipment for everyone, hoping to help everyone:

Vacuum equipment products can be divided into five categories:

(1), vacuum acquisition equipment-a device for generating, improving or maintaining vacuum. Includes various vacuum pumps and vacuum units for obtaining coarse, low, medium, high and ultra high.

A. mechanical vacuum pumps: rotary vane pump, reciprocating pump, slide valve pump, roots pump, molecular pump and liquid ring pump, etc.

B steam flow vacuum pump: steam jet pump, oil booster pump and oil diffusion pump, etc. C. Gas trapping vacuum pumps: titanium sputtering ion pump, cryogenic pump, molecular sieve adsorption pump and zirconium-aluminum suction pump, etc.

D vacuum units: all kinds of units composed of components such as generating vacuum, measuring vacuum and controlling vacuum.

(2) Vacuum application equipment ~ all kinds of equipment applied in vacuum environment (gas state below one atmosphere)

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.

C, vacuum heat treatment furnace: quenching furnace, tempering furnace, annealing furnace, carburizing furnace, nitriding furnace and metal infiltration 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 machine and molten steel degassing device, etc.

(3) Vacuum measuring instrument-an instrument for measuring the pressure of gas and steam below one atmosphere.

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 is an instrument for detecting the position or leak rate of a vacuum system or component leak hole. Include high frequency spark leak detector, halogen leak detector and helium mass spectrometer leak detector.

(5), vacuum valve in the vacuum system, used to adjust the flow, cut off or connect the pipeline components. Including flashboard valve, flapper valve, electromagnetic valve, electromagnetic band vent valve, diaphragm valve and regulating valve.

Principle introduction of vacuum coating machine ;

The vacuum coating machine is mainly used for coating equipment under high vacuum degree, and its coating technology specifically includes many kinds, such as vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, ion beam sputtering and so on. When daily vacuum coating machines are applied to different fields, we will take different names, such as applied optics, then we will become optical vacuum coating machines and applied to flexible materials, then we will become web vacuum coating machines, auto parts vacuum coating machines, hard coating vacuum coating machines, decorative vacuum coating machines and so on. Vacuum coating machines are widely used in electronic products, building hardware, watchmaking, large-scale workpieces, auto parts, spare parts, and daily application products in life, etc. Therefore, vacuum coating machines are in great demand in the market.
