In manufacturing there is a need for high altitude testing or off gassing of materials or similar application where a controlled and repeatable vacuum environment is required. Our product line focuses on a cost effective vacuum chamber of virtually any size that is easy to use and less expensive than conventional tooling. As a result, we offer a flexible chamber system based on aluminum extrusion profiles and customization according to your specific manufacturing requirements.
Our vacuum chambers are manufactured from aluminium in various cross sections in length up to 3 meters long. Pumping systems are determined by application and desired pressure and process time. Process control systems vary based on customer requirements.
The benefits of these vacuum chamber system are:
With vacuum degassing, volatile substances such as solvents or moisture are removed in a controlled process. Many materials need degassing to eliminate the negative effects of the volatile substances. The following negative effects may occur for example: bad smell, loss of adhesion when gluing, painting or coating. For degassing, the parts are exposed to a defined vacuum for a specific time.
The process used in vacuum drying is almost identical with the degassing process. Vacuum drying is used to dry products saturated with liquids such as water or solvents. The major benefit of vacuum drying is the low temperatures. The lower the pressure, the lower the temperature at which water passes from the liquid to the vapour phase.
This ensures very gentle drying of high-value and sensitive products at low temperatures.
Another variety of vacuum degassing is manual vacuum casting. Bubble-free casting is mandatory for high-value and heavily loaded components. With manual vacuum casting, the parts are cast at atmospheric pressure. Next, they are exposed to gas in a vacuum chamber. This makes premium-quality bubble-free manual casting possible. This is of advantage above all for small series production as well as for research and development purposes. With manual vacuum casting, running suitable pressure ramps is a precondition for achieving optimum results. It is also possible to use special casting compounds not suitable for standard casting systems.
Simulation of high altitude testing for air transport is a mandatory requirement for many components. While there is pressure equalization in the cargo holds of aircraft, it cannot completely compensate for the pressure fluctuations. The pressure can fall below 800 mbar. In an electronic test plant, the components can be exposed to a pressure simulation test. Also significantly lower pressure levels can be simulated to test the behaviour for example during a pressure drop.
In aviation and space exploration some components such as electric motors are operated outside of the pressurized cabins. Product testing for function must be completed. With suitable vacuum feedthroughs, motors and other devices can be operated and tested inside a vacuum chamber
Components used in space must be able to withstand even much higher loads. For these applications, pressures of 10-6 mbar and lower must be simulated. To achieve pressures as low as this, a turbo molecular pump with a suitable backing pump is required.
