In terms of vacuuming process, what are the applications of vacuum technology?

Vacuuming, the removal of air or gas from a sealed container, is one of the most extensive applications of vacuum technology, and with many kinds of application.

Vacuuming, in most ambient air industrial applications, is generally defined as  emptying  the physical space of the gas. Vacuuming is necessary when the presence of ambient air or oxygen interferes with the manufacturing or testing process

The vacuum requirements vary depend on the application, from the low vacuum required for central vacuum systems to the high vacuum required for semiconductor production of silicon wafer coatings

Examples of PRONOTEK vacuum technology used in extraction process：

Vacuum packing -- vacuum the packing cavity

Container vacuum system -- a vacuum container maintains a vacuum for a long time

Heat treatment -- vacuum furnace evacuation

Surface coating -- vacuum coating chamber

Mould degassing - casting quality optimization

Space simulation - space simulation room pumping

Transfer room - wafer production

Processing  room- mainly used in semiconductor production
