High-Precision PQ Vacuum Brazing Furnace - Leading China Suppliers & Factory for Complex Component Welding
Heat the workpiece under different vacuum (10-2~10-6 mbar), remove the adsorbed gas and impurities on the surface of the workpiece, and avoid weld porosity and inclusion defects.
Multi-zone independent temperature control, combined with PID algorithm, to achieve ±5℃ furnace temperature uniformity, with good temperature control accuracy.
Through inert gas nitrogen under different cooling pressure, combined with high-speed large flow fan to quickly cool the workpiece, cooling speed is controllable.
According to the uniqueness and complexity of vacuum brazing process, it is equipped with multiple protection mechanisms to eliminate potential risks from all aspects and multiple dimensions, and fully ensure the safe operation of equipment.
Support the overall brazing of complex workpieces such as multi-layer laminated sheets, honeycomb structure, small runner (such as heat exchanger fins, rocket nozzle) to achieve high-precision assembly and sealing.
Can braze the combination of heterogeneous materials, through the gradient transition layer design to alleviate the stress problem caused by the difference in thermal expansion coefficient.
Choose a flexible opening method of the furnace door according to the customer's on-site requirements (such as the door position left and right direction, automatic or manual opening).
Integrated PLC, with program controller or computer interface, touch screen, recorder and other real-time monitoring furnace vacuum degree, temperature, pressure and other data, support remote fault diagnosis and process tracing.

The furnaces can operate under a working vacuum ranging from 10-1 to 10-6 mbar (optional). Heating under these conditions removes adsorbed gas and surface impurities, preventing weld porosity and inclusion defects.
It features multi-zone independent temperature control combined with a PID algorithm to achieve a furnace temperature uniformity of ±5℃, ensuring superior temperature control accuracy.
Cooling is achieved using inert gas (Nitrogen or Argon) under controlled pressure (0.87 to 2.8 barabs, up to 10 barabs), paired with a high-speed, large-flow fan for a fully controllable cooling speed.
Yes. It supports the overall brazing of complex workpieces (like honeycomb structures and heat exchanger fins) and can join heterogeneous materials using a gradient transition layer to reduce thermal expansion stress.
Absolutely. We support customization for effective working area size, maximum operating temperature, working vacuum levels, gas cooling pressure, and other parameters to match your specific production requirements.
