Laser Beam Welding Low Vacuum Purge Chamber sitting on a pallet
This was actually not a vacuum chamber per se but more like a vacuum purge unit. Our customer, who is from academia. had gotten a custom made CNC laser beam welding unit. They were looking for a way to purge the surrounding air and fill it with inert gas in order to prevent oxidation and contamination from the laser heat source. We suggested several small chambers with a viewport for their laser welder. However, they wanted to encase the whole CNC unit inside a chamber which would be lift able by a crane for easy access.

After going back and forth with us trying to talk them out of getting such a large chamber and encasing the whole unit, we finally agreed because they were only looking to purge the air out and inject argon; hence this unit would never go below a gauge vacuum of - 3psi.

What you see here is a vacuum purge chamber for a CNC laser welder with dimensions of 28 inch wide, 30 inch deep, and 35 inch high. The whole chamber sits on an aluminum plate that has clamps in order to clamp down the chamber during the purging process. We also added a lifting holes and reinforcement ribs for structural robustness in case one of their graduate students forgets to turn off the vacuum pump...

Stainless Steel Vacuum Chambers
Stainless Steel Vacuum Chambers are vacuum chambers made from stainless steel. The advantages of a Stainless Steel Vacuum Chamber are High Vacuum and a Wide Temperature Range of applications.
Digital Vacuum Gauge Instruments
A Digital Vacuum Gauge is an instrument which precisely measures a vacuum level inside a vacuum chamber. Unlike a rough dial vacuum gauge, which shows only where the vacuum chamber is roughly with an error of up to 3% (a high as 1 inHg) a digital vacuum gauge will show vacuum levels up to 3 significant figure in Torr and millitorr – this makes the digital vacuum gauge ten thousand times more accurate than the dial vacuum gauge.
Our Work: Custom Vacuum Chamber with Blank Plate
You are looking at our standard Acrylic Vacuum Chamber, Hinged Door with Clamps. There is only one difference; this vacuum chamber has a blank acrylic plate that is connected to and aluminum plate which in turn is anchored to the side wall of the acrylic vacuum chamber. This blank plate is there to enable our client to add vacuum feedthroughs to the side wall in the future
