Vacuum Encapsulation of Aerospace Devices using Sanatron Equipment
Vacuum Encapsulation is a process of encasing items by utilizing a vacuum chamber. There are several reasons why encapsulation may be necessary, however they all boil down to protecting the original product thru sheathing or coating.

An aerospace customer of ours needed to build a vacuum encapsulation system for one of their product lines. This system included a vacuum chamber, a vacuum controller, a vacuum pump, a custom adjustable jig (placed inside the vacuum chamber), and several feedthroughs for wires and liquid gas feedthrough. The vacuum chamber was 18 inch Wide, 18 inch Deep, and 18 inch High with front loading hinged door. The vacuum pump which came with the system was a 11 CFM, Rotary Vane Vacuum Pump capable of reaching ultimate vacuum of up to 0.010 Torr or 10 milliTorr absolute pressure.

The vacuum encapsulation process works by placing the product onto the adjustable jig. Pulling the target vacuum of 0.475 Torr or 475 milliTorr. Holding it there for about 20 seconds. After 20 seconds have elapsed, the product is ready for vacuum potting. A nozzle will be rotated and placed directly above the product, the potting valve opens, and potting epoxy is dispensed onto the product fully covering it. Once the required amount of potting epoxy has been dispensed, the venting valve will open and the product will be brought to ambient pressures. Due to vacuum being present when the potting compound was dispensed, any gaps will be filled due to the fact that the vacuum is present inside the gap and ambient pressure present outside of the potting compound. If you are looking for a vacuum potting or encapsulation system, look no further, we have a wide variety of Vacuum Encapsulation systems which can be either manual or fully automated for a fully repeatable quality process. Contact us to find out how we can help you design, build, and deliver a quality built vacuum encapsulation system.

Vacuum Bubble Emission ASTM 3078 Leak Testing Systems
Bubble Emission (ASTM 3078) Leak Testing Systems are instruments that are used during the Quality Control process discover and locate leaks or seal integrity failures. Leaks are detected by submerging the specimen into a tank of water, applying a vacuum, and inspecting the submersed specimen for bubble emission. Our Bubble Leak Testing Systems are designed and built to conform to the ASTM D3078 protocol standard.
Rotary Vacuum Feedthroughs
Rotary Vacuum Feedthroughs are devices that will enable you to physically rotate a specimen inside the vacuum chamber while vacuum present without decreasing the vacuum.
Our Work: Research, Development, and Testing of Weather Balloons inside a Clear Vacuum Chamber
A wonderful company (more like one of the best companies in the world) which is currently involved with the research, development, and testing of high-altitude weather balloons, had a need for a vacuum chamber capable of achieving about 100 micro Torr (Micron) of ultimate Pressure for their testing environment. Fortunately, acrylic vacuum chambers are the perfect choice when it comes to Low, Rough, and Medium Vacuum.

Bubble Leak Testing or Bubble Emission Testing is a procedure where leaks are visually detected and located through the emission of bubbles while the test specimen is submerged in water. In this article, we will talk about using an acrylic vacuum box as a leak detection device. We are also going to talk about the advantage, disadvantage, and the bubble leak emission test procedures.
