What is a vacuum chamber?
A vacuum chamber is a sealed container or space where the internal pressure is reduced to an extremely low level, approaching or reaching a state of vacuum by removing gases or other substances. Within the vacuum chamber, a depressurization system withdraws gases, evaporates liquids, or uses other methods to decrease pressure, resulting in an extremely low or near-vacuum environment. Vacuum chambers are commonly used in scientific experiments, industrial manufacturing, and various other applications.
These chambers are employed to simulate outer space environments, conduct material processing, manufacture electronic devices, among other fields. They serve to eliminate gases, particles, or other impurities that may interfere with experiments or manufacturing processes, thus holding significant application value across numerous domains.
The most commonly used materials for vacuum chambers are stainless steel, aluminum, and carbon steel. Customized vacuum chambers can come in various shapes, including rectangle, cylinder, box, D-shape, spherical, polygon, bell jar, and multi-edge.
MillstongTech offers several surface treatment options for vacuum chambers, such as sandblasting, polishing, and electropolishing. Additionally, we provide vacuum chamber stress relief processes through heat treatment or vibration methods. Moreover, modules or systems can be assembled and tested in our working shop, reducing lead times and logistic costs for our clients.
