The history of Millinocket is filled with experiences in vacuum chamber fabrication. In particular, we know how to build and design them well due to a manufacturing process that has made hundreds over the years. Our continued experience ensures you’ll get as much precision machining from us for your project as possible. Once fabrication is complete, we can use the helium leak rate test method to ensure that you have a high-quality vacuum chamber. With our experience in fabricating vacuum chambers of all sizes and weights, we can make sure your project’s needs are met.
Custom vacuum chambers
We have been providing custom vacuum chamber construction for a number of industrial applications for decades. Millinocket’s custom vacuum chambers are perfect for semiconductor equipment, research, PV tools, and particle accelerator components. We specialize in producing aluminum, steel, and stainless-steel vacuum chambers for customers. With state-of-the-art technology, Millinocket has been able to develop high-volume production engineered vacuum chambers.
Vacuum chambers are large, protective enclosures that we use to contain vacuum treatment processes inside the furnace. One or more door(s) for the loading and unloading of parts that prevent them from coming into contact with the furnace are attached to an outer shell that encloses a vacuum. The look of the Vacuum Chamber is very similar to an autoclave or a horizontal pressure vessel.
Fabricating and assembling a Vacuum Furnace will start with ASME code calculations if there is a positive pressure in the Chamber, but always begins with drawings supplied by Millinocket or the furnace OEM. Fabrication includes:
- Plate rolling
- Fitting of nozzles and flanges
- Machining of chamber and door flanges
- Welding to ASME standards
- Blasting and painting
Vacuum chamber testing
Millinocket’s custom vacuum chamber fabrication department manufactures custom vacuum chambers in carbon steel, stainless steel, and aluminum. Depending on your custom vacuum requirements, custom vacuum chambers can be made using a variety of materials.
