1. Ultimate craftsmanship quality: high precision and high reliability
Non oxidizing welding environment
The vacuum environment (with a vacuum degree of up to 10 ⁻ Pa or even higher) isolates oxygen, completely eliminating the problem of high-temperature oxidation of aluminum materials. The weld forms a dense metal bond, and the mechanical properties are close to the level of the base metal.
Uniform temperature field control
Through independent temperature control in multiple temperature zones and intelligent algorithms, the temperature uniformity inside the furnace is achieved within ± 5 ℃, avoiding local overheating or incomplete welding.
Low stress and high sealing performance
Slow heating/cooling cycles reduce residual stress, weld meniscus design reduces stress concentration, and fatigue performance is improved.
2. Wide material adaptability: breaking through the limitations of traditional welding
Ability to connect dissimilar materials
It can weld dissimilar metals such as aluminum, copper, stainless steel, titanium alloys, and even non-metallic materials such as ceramics to meet the requirements of complex components. For example, in the aerospace industry, lightweight structural manufacturing is achieved through vacuum aluminum welding, significantly improving the connection strength between aircraft skin and engine components.
Compatibility between thin-walled and thick section
Accurate temperature control technology ensures that thin plate workpieces do not deform, while monitoring the insulation time of thick sections through workpiece thermocouples to achieve uniform heating. For example, the intercooler of a car radiator adopts vacuum brazing, and the thin-walled pipe is connected to the thick substrate without deformation, with excellent sealing performance.
Ability to handle complex structures
Suitable for complex structures such as 3D flow channels and multi joint components, capillary action ensures uniform filling of narrow channels with solder material. For example, high-precision parts of medical equipment are connected without contamination throughout the entire process through vacuum aluminum welding, meeting strict cleanliness standards.
3. Efficient production mode: combination of batch production and flexibility
Multiple workpieces processed in the same furnace
A single batch can process tens to hundreds of workpieces, significantly increasing production capacity.
Rapid process cycle
The vacuum furnace has fast vacuuming and heating speed, combined with the high thermal conductivity of aluminum materials, which shortens the overall process time.
Modular design with flexible adaptation
We offer intermittent (single chamber) and semi continuous (multi chamber) furnace types, supporting vertical/horizontal loading to meet different batch requirements.
4. Green environmental advantages: zero pollution and low energy consumption
Helpless soldering process
Eliminate corrosive flux residue, avoid chemical pollution, and reduce subsequent cleaning processes. For example, vacuum aluminum welding technology ensures that there is no wastewater discharge during the equipment production process, which complies with green manufacturing standards.
Low energy design
Efficient insulation materials and intelligent temperature control systems reduce heat loss and lower energy consumption compared to traditional welding.
Optimization of exhaust gas treatment
The vacuum system effectively controls process by-products (such as magnesium vapor) to avoid irritating chemicals or molten salt contamination. For example, the vacuum aluminum welding furnace is equipped with a molecular pump and a cold trap, and the exhaust emissions meet the EU RoHS standard.
5. Intelligent Control: Industrial Benchmark
Real time quality monitoring
Integrated infrared temperature measurement and visual inspection system, monitoring the formation of welds and temperature curves throughout the process, with traceable data. For example, in the production of high-power chip cold plates, the vacuum aluminum welding furnace realizes cloud storage of process parameters for each product, reducing quality traceability time to minutes.
Adaptive process adjustment
AI algorithms automatically optimize heating power and vacuum degree based on material thickness and structural complexity, resulting in improved yield. For example, in the production of battery packs, the vacuum aluminum welding furnace dynamically adjusts process parameters through machine learning models, resulting in a decrease in defect rates.
Remote operation and predictive maintenance
The IoT module supports real-time uploading of device status, combined with big data analysis to predict faults and reduce downtime.
