Vacuum chambers are rigid enclosures from which all traces of gas and air is removed by means of a vacuum pump. These types of chambers are mainly used by scientists and researchers to conduct experiments in a non-combustible environment. The spaces are generally consists of light weight aluminum to allow test managers to control, maintain and modulate the magnetic field within the enclosure. In case of those trials where the magnetic field within the chamber should not be influenced by external permanent magnet sources, mu-metal can be used to construct the exterior walls of the chambers.

Vacuum compartments are being used for a amount of industrial tests and applications like thin movie deposition, and spectroscopy. Also, they are used for manufacturing semi-conductors, where it is of utmost importance to ensure there is no contamination of the substrates, as the minutest level of adulteration can result in dangerous commercial accidents.

These alcoves are generally installed with multiple number of ports. These slots have a protective addressing of flanges, to ensure that windows and gadgets can be installed to the walls of the step. In some processes that require that is only low to medium range vacuum, the openings are sealed with circular rubber rings. Inside other processes that employ extremely high degrees of vacuum, the flanges are often made of hardened steel to be sealed on to the copper gaskets.

Energy vacuum chambers are often used for the objective of conduction of tests on spacecrafts while they are being designed and manufactured. This is important, as it would help engineers to make the correct measurements. Such tests give a clear idea about the quality and strength of spacecrafts, as by tests the vessel in a situation similar to that of outer space, designers and manufacturers can ascertain the strengths and weaknesses of the spaceship. Vacuum chambers are also used when there is a need to mix silicon rubber and resins. A new rarefied environment is necessary to ensure that there is no accidental occurrence of air bubbles in the mold. A small chamber is required to remove all traces of air and air bubbles before the final setting. It is recommended to make use of ultra-high vacuum chambers just for this process, as the slightest footprints of contamination can cause fatal industrial accidents.

Materials used for casting and molding are made under the strict instructions of the manufacturer. When such materials are positioned in a vacuum chamber, their inclination is to expand by almost four times the normal size. Therefore , for such purposes, it is best to use a chamber that can accommodate the expanded quantity. The container that encloses the casting or creating material is first placed inside the vacuum step, following which, a link is made with a vacuum water pump. After all settings are properly installed and encased, the pump is switched on. The expansion of the substrate will be initiated only after the levels have been brought up to about 982 mbar. The inflation will stop once the material has expanded to its maximum capacity. Once it offers attained a stable state, it could be deduced that all remnants of air has been taken out of the mold or cast. However, it is a wise move to run the vacuum pump motor for some more minutes to ensure complete removal of air bubbles. Once the process is complete, the machine is switched off, and the lid is opened to equalize the air pressure.
