Principle

The small vacuum tungsten wire sintering furnace is a resistance sintering furnace that utilizes tungsten wire as the heating element. The furnace body is made of high-temperature resistant materials and has a vacuum-tight structure. The working principle is to place the material to be sintered in the furnace chamber, evacuate the air inside the chamber to create a vacuum environment, and then pass a current through the tungsten wire to generate heat. The high temperature generated by the tungsten wire causes the material to undergo a series of physical and chemical changes, such as diffusion, thermal cracking, and chemical reactions, which promote the reorganization and recrystallization of the material at the microscopic level. This process results in the formation of a dense structure and excellent performance while preventing oxidation and pollution of the material.

Advantages

• High vacuum degree: The vacuum pressure can reach 1.3*10^-1 Pascal, which is equivalent to 99.99987% argon purity, effectively reducing the contamination of harmful substances in the atmosphere.
• Versatile: Suitable for fast and high-end sintering of various materials such as metals, ceramics, nanomaterials, non-crystalline materials, composite materials, and functionally graded materials.
• Easy operation: User-friendly design with fully automatic control for vacuum pumping, pressure increasing, and sintering. Interlocking function and alarms ensure safety.
• Compact and mobile: Vertical structure with integrated control cabinet and furnace body, equipped with moving wheels for easy movement and space-saving.
• Reliable performance: High-quality electrical components from Omron or Schneider ensure stable control, and a classified sound and light alarm function simplifies troubleshooting.
• Precision construction: Precision-polished inner surfaces of the furnace shell and cover with a smooth finish better than Δ6. Helium mass spectrometer vacuum leak detector testing guarantees accurate pressure rise rate data.
• Energy-efficient: Electrically lifted furnace bottom for smoother operation and high reliability, reducing water consumption.
