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 are an Engineering Excellence Company. Check out some of our other items we carry that you can combine/integrate with your systems or projects.

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.
BNC Vacuum Feedthroughs
Coaxial Vacuum Feedthroughs are vacuum rated BNC connectors that enable you to run BNC from outside of vacuum chamber towards inside of the vacuum chamber without disturbing the vacuum. Triaxial Vacuum Feedthroughs, just like coax vacuum feedthroughs, will enable you to run Triax Connections from outside towards the inside of the vacuum chamber without disturbing the vacuum levels inside the vacuum chamber.
Our Work: Submersion Leak Testing of Explosive or Volatile Products
Ever wondered how to leak test packaged volatile products? Do you know that there are countless unstable products out there that have to be leak tested as part of quality control? By volatile we mean products which ignite, explode, shatter, melt, or are hazardous. Keep in mind that hazardous material for whatever reason has be undergo quality control as well.
