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...

Vacuum Oven Systems
Vacuum Ovens are vacuum chambers and ovens combined in one system. Vacuum ovens are necessary during processes which require the specimen to be subjected to a hypobaric and hyperthermal environment. Our Vacuum Oven Systems enable to you run a complete vacuum vs time and temperature vs time profile. We also carry portable vacuum oven systems and custom vacuum oven systems.
Altitude Simulation Controller Instruments
An Altitude simulation Controller is type of vacuum controller that simulates a certain altitude because altitude can be derived from vacuum levels. An altitude simulation controller will enable you to hold your vacuum level at a certain altitude equivalent of testing, run an altitude vs time profile, or rate of change of altitude vs. time. Further options include a vacuum pump relay that will control when the vacuum pump turns on and a vacuum valve.
Our Work: Chamber for Vacuum Extrusion System
This is a custom acrylic vacuum chamber build for a high volume manufacturer of parts which are fabricated using vacuum extrusion techniques. The challenge was to build a vacuum chamber system which mated on two perpendicular surfaces; on the bottom and on the rear of the chamber. This was accomplished by incorporating a double gasket mechanism on the bottom and incorporating a clamping mechanism on the rear.
