Our Work

Below you will find examples of what we do and how we do it.

Chamber for Vacuum Extrusion System

vacuum extrusion system chamber

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.

High Altitude Vacuum Testing of Electrical Connectors and Components

This was an interesting project where one of our customers needed to test wires up to 44 inches long within a high altitude simulation environment. In addition to testing wires, several other electric connectors required altitude testing as well. The altitude requirements were 100,000 feet (30.510 km) which corresponds to 8.36 Torr - a piece of cake when it comes to the vacuum requirements of our chambers.

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.

Vacuum Testing of Lithium Ion Batteries, Thin Film, Fuel Cells, Supercapacitors, and Nano materials

This vacuum chamber is a modification to our basic acrylic vacuum chamber 12 inch, removable lid model; except that our customer requested additional ports and electrical feed-through for testing of electrical equipment under vacuum. You know, I wish we would have asked them for more details on what they were doing with this chamber; their short and concise answer was that they were using our chamber to perform scientific work on the subjects of: lithium ion batteries, thin films, fuel cells, super-capacitors, and nano-materials testing in a vacuum environment.

Laser Beam Welding Low Vacuum Purge Chamber

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.

Testing of High Potential Voltage Cable Discharge Arc Using a Cylindrical Vacuum Chamber.

Testing of High Potential Voltage Cable Discharge Arc Using a Cylindrical Vacuum Chamber 01

This cylindrical vacuum chamber is utilized for testing high potential voltage cables for potential discharging at higher altitudes. Since air is acting as an insulator at sea level, no electric discharge is present at lower altitudes. However, once the pressure is decreased as a result of higher altitudes, less air is present to act as an insulator. This creates a problem because if an electric discharge happens, it can result in catastrophic failure of electrical components, especially if these components are critical. It is therefore very important to test these cables for discharge by using a vacuum chamber to simulate an air pressure at higher altitudes. The vacuum requirements for this test where only to go to 35,000 feet pressure equivalent which is about 165 Torr.

Vacuum sample preparation and laboratory testing

Vacuum sample preparation and laboratory testing

This is our standard 10 inch cube inside dimensions chamber made for vacuum sample preparation and laboratory testing. Our client needed a vacuum chamber that is high performing and robust which is why they came to us. This chamber has a vacuum rating of 250 microns absolute pressure. Included as a standard are: a vacuum valve, a vent valve, a vacuum gauge, two toggle clamps, two hinges, one handle.

Vacuum Soil Sampling and Extraction for Geological Research

What you see here are two identical vacuum chambers with a spring supported lid which are used in vacuum soil testing and extraction methods. Our client asked us to provide them with two vacuum chambers capable of reaching vacuums below 1 Torr absolute.

Microfluidic Testing using an acrylic vacuum chamber

Our client performs a wide array of microfluidic testing in their laboratory. The requirements were 1. to install injection ports which are connected to a syringe pump outside of the chamber, 2. A gas port to pump gas such as carbon dioxide, helium, or argon into the specimen, 3. an electric feedthrough port in order to connect a heat plate and heat the sample inside the chamber during vacuum tests.

Phototesting of different materials through vacuum, airflow, and laser

This was a fun project as it involved a custom chamber with the following items: a front door, two airflow diffusers (inside plate with lots of holes), four spare ports, top hole and bottom hole with a gasket to allow for different specimen to be placed, clamped, and tested.

Testing High Voltage Circuit Boards 350V at a Simulated Altitude of 60,000 Feet

What you are seeing here is our crystal clear acrylic vacuum chamber, hinged side door with clamps. In addition, our client has asked us to add 1. A quantity of two high power feedthroughs on the top right wall, 2. An 8-pin power connector, and 3. a multi-pin feed through. These vacuum feedthroughs enable the routing of electrical power and signals from the outside of the chamber into the inside of the chamber without disrupting the vacuum.
