2. Vacuum packing - Wikipedia

   en.wikipedia.org/wiki/Vacuum_packing

   Vacuum packing is a method of packaging that removes air from the package prior to sealing. This method involves placing items in a plastic film package, removing air from inside and sealing the package. [ 1] Shrink film is sometimes used to have a tight fit to the contents. The intent of vacuum packing is usually to remove oxygen from the ...

   Torr-Seal, or its generic equivalent Hysol-1C (US brand name) or Loctite 9492 (EU brand name), is an epoxy with resin and hardener for use in vacuum environments. It will begin to degrade at high temperatures but otherwise is very stable with very little outgassing. Other vacuum-rated epoxies are also available.

4. Vacuum table - Wikipedia

   en.wikipedia.org/wiki/Vacuum_table

   A vacuum table is a system for holding workpieces during machining. The device consists of a perforated table top containing a vacuum chamber, and a vacuum pump to keep the vacuum chamber below ambient enough pressure. The workpiece is placed on the top of the vacuum chamber and thus held down by the pressure differential between the vacuum ...

5. Porosity sealing - Wikipedia

   en.wikipedia.org/wiki/Porosity_sealing

   Porosity sealing. Porosity sealing is done through the process of vacuum impregnation. Vacuum impregnation is a preferred OEM process that seals porosity and leak paths in metal castings, sintered metal parts and electrical castings that form during the casting or molding process. Vacuum impregnation stops casting porosity (a phenomenon that ...

6. Vacuum insulated panel - Wikipedia

   en.wikipedia.org/wiki/Vacuum_insulated_panel

   A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction, refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials. [ 1] [ 2]

7. Vacuum chamber - Wikipedia

   en.wikipedia.org/wiki/Vacuum_chamber

   Vacuum chamber. A large vacuum chamber. A small vacuum chamber for studio or lab use in de-airing materials such as mold rubbers and resins. A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump. This results in a low- pressure environment within the chamber, commonly referred to as a vacuum.
