Chamber for Vacuum Extrusion System

Rear view of the Custom Vacuum Extrusion Chamber
This is a custom acrylic vacuum chamber build for a high volume manufacturer of parts that are fabricated using vacuum extrusion techniques. The challenge was to build a vacuum chamber system which interfaced on 3 sides with various in-house extrusion equipment components in order to create a good vacuum seal. The bottom, the top, and on the rear of the chamber had to interfere with the vacuum extruder assembly. This was accomplished by incorporating a double gasket mechanism on the bottom and top and by incorporating a clamping mechanism on the rear. The top of the chamber interfaced with extrusion cutting equipment. The rear of the chamber interfaced with the vacuum extrusion die. The bottom of the chamber interfaced with the vacuum hopper.

The advantages of using an acrylic vacuum chamber in vacuum extrusion environments is that it allows for full visibility of the product. Additionally, a camera system can be added to the operation enabling fully visual inspection of the interior hence increasing throughput, quality, and safety.

On a personal note, this was a very tricky engineering problem because we were aiming to design a chamber which had to create a vacuum tight fit against three surfaces which were not completely perpendicular to each other due to wear and tear. This was accomplished by using a double gasket aluminum interface plate.

In the end, all went well, and looking back we have nothing but gratitude to this customer for giving us a chance to push ourselves beyond what we were comfortable doing - hence making us better engineers. This was a challenging and fun project; not only were we able solve a problem they were wrestling with for quite some time, we also made friends and connected with people on the other side of this country.

Did you know that we carry a many more products?

We make Robustly Designed and Quality Engineered Systems. Check out some of our other items we carry that you can combine/integrate with your systems or projects.

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.
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: Modified 14 inch Cube Vacuum Chamber for Degassing
This custom job was a modification to our standard acrylic vacuum chambers. When it comes to working with the Us Military, they want all specs to be met 110% and they want it yesterday. The military does not mess around which is why they came to us since we know how important it is to meet specs and ship fast.
