Vacuum Aluminum Brazing Furnaces
Vacuum Aluminum Brazing (VAB) is utilized to perform fluxless brazing of Aluminum components in a high vacuum environment. The process demands tight control of temperature uniformity together with low vacuum leak rates and high repeatability. VAB will provide a component with very clean, high quality, high strength brazed joints. Whilst offering a wide range of standard vacuum aluminum brazing furnace designs for a variety of applications, Consarc also has the flexibility to design for bespoke or individual customer requirements.
Features
- Closely spaced ribbon heating elements with the edges facing the work provide the best in uniform heating characteristics.
- Temperature uniformity +/- 5oF
- Multiple ‘trimable’ heating panels for balance of heat input to match the workload and fixture thermal characteristics.
- Trimable heating panels up the height of the hot zone allows the heat input to be trimmed to match components /charge loads of varying height.
- Aluminum debris will pass through the edge facing bottom heating element panels – minimising potential for burn outs.
- The hot zone element panel modules can be easily removed to permit cleaning of the furnace. Individual panels can also be removed without the need for a full hot zone strip down.
- Element repairs made simple. Small sections of the strip elements can be repaired without the need for full replacement
- Hot zone shields are overlapped and spaced to permit easy escape of gases from the work assembly to provide optimum vacuum performance.
- The tank walls of the furnace are maintained in a hot condition to prevent condensation of atmospheric moisture when the chamber door is open.
- Insulated non-water cooled power feedthroughs prevent condensation of magnesium which reduces arcing potential.
- Internal inert gas cooling systems or external air blast cooling stations are available
- Fully integrated and automated loading systems.
- Integration with a Vacuum Deoiing furnace to provide an “in line” process system for high productivity with minimum product handling.
- Extensive process experience.
- PLC and PC SCADA providing completely automated control of the brazing furnace and data recording
- Compliant with NADCAP and AMS2750 requirements if required
- Complete furnace system including all interconnecting services, water lines, air lines, gas lines and electrical cables.
- Fully assembled and functionally tested prior to shipment
