A vacuum chamber is an enclosed container used to test the effects of vacuum pressure on various materials, parts, assemblies, or components.Vacuum Chambers test an item by simulating environmental pressure conditions.In manufacturing operations, a vacuum chamber is used to evaluate a particular part or device’sability to withstand the pressure inside the chamber.

Applications for Vacuum Chambers

Various industries utilize vacuum chambers to improve a process or procedure. Some applications include:
• Outgassing or drying materials with high moisture content.

• Simulatinghigh altitude conditions as in the aerospace or aeronautics industries.
• Storing moisture sensitive materials.
• Removing unwanted odor from an item.
• Ensuring uniform mixing of materials in component manufacturing.
Stainless Steel thePreferred Material for Vacuum Chambers
Manufacturers prefer stainless steel when constructing vacuum chamber equipment. Stainless steel has certain propertieswhich make it the material of choice. Properties include:
• Manufacturing and Machining Convenience
• Corrosion Resistance
• Mechanical Strength
• ExcellentWeldability
• Tolerance to Temperature Variations
• Level of Magnetic Permeability
• Durability
• Visually Appealing
Other materials may require paint or galvanizing, whichwould increase pumping times, and may also lead to contamination of the process atmosphere.Stainless steel can withstand even hot oxidation and is good for internal heating treatment, without the formation of oxide.It can be easily cut with modern laser cutting systems and is a better option than carbon steel.

Aerospace and Manufacturing

The aerospace and manufacturing industriescomprise the largest use of vacuum chambers because of the kind of environmental exposure their products go through. Almost every part or product used in the aerospace industry must be tested to ensure safety and the highest performance standards.The integrity of bolts and switches to panels, electrical components, seat cushions, even latches and door handles need to be vigorously tested. These tests are done using vacuum chambers.

In manufacturing, vacuum chambers are used to highlight product flaws such as leaks or resistance, applycoatings, and remove moisture.
