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. During the fabrication phase, our client did not know what vacuum feedthroughs they would need in the future. We decided that it was best to simply add a blank acrylic plate which can be removed, customized, and fastened back to the acrylic vacuum chamber. Additionally, our client would have the option to envision, design, and fabricated their own additional custom vacuum plates should that need arise in the near future.

Now to the Aluminum Part, why is there an aluminum plate anchored to the acrylic side wall? Well, the aluminum plate is there to increase the service life of the threads. We do not like to thread into the acrylic walls of our vacuum chamber, what we do instead is we press threaded inserts into pre-drilled holes. When a bolt is being fastened into the threaded insert, the insert will slightly expand and grab onto the hole wall; hence anchor. The threaded insert creates a compression force on the acrylic walls instead of a shear force had we threaded the hole instead. Acrylic is able to handle compressive forces of the insert a lot better, it does not does not do too well during shearing forces. If the shear force is too high, the walls will begin to craze.

So, there you have it, this is why we have the aluminum plate there. Our customer will fasten the blank plate to the aluminum instead of threading into the acrylic.

Portable Vacuum Chamber and Pump Systems
We carry a wide range of portable vacuum chamber and pump systems. A Portable Vacuum Chamber and Pump system is placed onto a frame structure and lockable swivel casters which enable you to move your vacuum chamber and pump system around your facility. Our portable vacuum systems are very popular among businesses that are constantly growing, evolving, or sharing. Our portable vacuum systems are moved with ease from location to location.
Viewport Vacuum Feedthroughs
Viewports Vacuum Feedthroughs are windows that enable you to look into the inside of your vacuum chamber. If you are using a metallic vacuum chamber with a metallic lid, you will not be able to view the interior of your vacuum chamber unless you have a viewport. Viewports also enable a different electromagnetic spectrum of light to passthroughs.
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.
Related Articles: Force Decay Leak Testing
Force Decay Leak Testing is a very popular quantitative leak testing method used to quality test package and product integrity due to its ability to detect small leaks which cannot be seen through visual inspection. In this method, the test specimen is internally inflated by either internal pressurization or vacuum force. The inflated test specimen will, in turn, apply a force on a pressure transducer. Finally, the change in force applied by the inflated specimen over a specified time is observed.
