Rotary vane pump and dry screw pump are the common vacuum pump in the market. Here I make a comparison with the application of screw pump and rotary vane vacuum pump in vacuum reaction sintering furnace. Rotary vane vacuum pump: Needs oil for working, easy backflow in the work, After the condens...

Vacuum coating principle refers to a certain metal or metal compound gas deposition on the specified material surface in vacuum environment, forming a coating, so called vacuum coating. Vacuum coating can be subdivided into evaporation coating, sputtering coating, ion coating and so on. The mater...

Aluminum vacuum brazing furnace body is composed of heating chamber, furnace, furnace front and back door, and various functional components. The heating chamber, stalled in furnace, is made up of a plurality of heating resistors and insulating layer. Heating resistors are connected with electro...

Heat Treatment is the process in which metallic/steel parts are exposed completely or partially to time-temperature sequences in order to change the mechanical and/or corrosion properties. There are numerous application areas, e.g.: • Annealing • Hardening • Tempering • Aging • Case hardening In ...

About the vacuum coating equipments Vacuum plays a decisive part in many coating operations in which metals, plastics or glass are deposited in vapor form. In many cases these processes would not be possible without vacuum. A medium or high vacuum is applied to the chamber for its evacuation at t...

Vacuum pump system have very nice application, for example vacuum coating, vacuum packing, Vacuum furnace, here we will introduce the vacuum system for vacuum coating machine. Normally we use KT series oil diffusion vacuum pump as main pump, ZJP series roost vacuum pump (roots booster pump) as se...
