Product Overview
Vacuum Aluminum Brazing Furnace is an intelligent industrial equipment designed for high-end aluminum brazing, adopting advanced vacuum brazing technology, suitable for automotive radiator, air conditioner evaporator/condenser, intercooler, radar antenna and other precision aluminum parts welding. Through oxidation-free heating and brazing material self-diffusion process in vacuum environment, it realizes high-strength, high-sealing and pollution-free welding of products, which is an environmentally friendly and efficient solution to replace traditional flame brazing and salt bath brazing.
Standard specification
Product Advantages
2.Excellent soldering quality
No porosity, no inclusions: the vacuum environment ensures uniform flow of brazing material, dense weld seam without defects, and improves the sealing and pressure resistance of the product.
High-precision temperature control: ±1℃ temperature uniformity ensures the consistency of welding complex structural parts, and the yield rate is as high as 99.5%.
Rapid heating technology: adopting high-efficiency heating element, the heating rate can reach 20℃/min, shortening the process cycle by 30%.
Intelligent energy-saving mode: waste heat recovery system reduces energy consumption, comprehensive energy saving of more than 40%.
4. Fully automated production:
Extend the life of the equipment: the cooling system is physically isolated from the heating module, which reduces the thermal stress damage of high temperature on the cooling parts and lowers the maintenance cost.
6. All-metal screen insulation structure
Intelligent monitoring: real-time display of the status of each temperature zone through the PLC + HMI human-machine interface, automatic alarms and record data in abnormal situations to ensure production traceability.
Core application areas
5G communication devices: all-metal screen structure ensures the cleanliness and signal stability of millimeter-wave antenna brazing.

Suggestions for selection：
Basic: suitable for small and medium-sized workpieces (such as automobile air conditioning pipeline), standard with single-zone temperature control + air cooling system.
Industrial: with multi-zone temperature control + nitrogen gas external cooling, supporting continuous production (optional conveyor) .
Customization: non-standard furnace design according to workpiece size (such as extra-long radar antenna), compatible with copper-aluminum composite brazing.
Through the synergistic optimization of the three core technologies of external circulation cooling, all-metal screen heat preservation and multi-zone temperature control, this equipment can realize high-efficiency, high-precision and non-polluting aluminum brazing process, which can satisfy the stringent demands of automotive, communication, aerospace and other fields for lightweight precision parts.
