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.

Did you know that we carry a many more products?

Our clients prefer to work with us because we are Experts in Custom Fabrication (especially Polymer Fabrication). Check out some of our other items we carry that you can combine/integrate with your systems or projects.

Altitude Simulation Systems
Altitude simulation systems are devices that simulate a certain altitude equivalent by controlling the vacuum inside a vacuum chamber. Altitude is a function of absolute pressure, therefore if a certain pressure is accomplished inside a vacuum chamber, a specific altitude can be simulated from the set pressure. Altitude simulation systems can be configured to not only hold a certain pressure, a complete pressure vs time profile can be programmed to be run. Furthermore, pressure vs time recipes can be loaded and run based on test requirements.
Piston Vacuum Pumps
Piston Vacuum Pumps are devices that generate a vacuum through the workings of an internal piston. Several advantages of a piston pump include, low maintenance, no oil mist emission since it’s an oil free vacuum pump – the shortcoming are not as high of vacuum levels and volumetric flow.
Our Work: Vacuum Storage of Pharmaceutical Products and Medical Supplies
A pharmaceutical manufacturer contacted us to build them a large vacuum storage system for their pharmaceutical products. They were looking for as much footprint as possible which is why they got a two-chamber system from us. They needed a total of 6 shelves per chamber including trays. Finally, they were looking to have both chambers to be placed on a table frame assembly with lockable swivel casters. What you are seeing is a two chamber system, each chamber is our 20 inch cube acrylic vacuum chamber, front load hinged door. Each chamber can be accesses independently while the other is under vacuum. The trays can be easily loaded and unloaded. This whole system can also be moved to anywhere in their facility.
