1. Temperature performance
Maximum operating temperature: Select a sintering furnace with sufficiently high temperature based on the melting point and reaction temperature of the sintered material. For example, certain specialty ceramics and high-temperature alloys may require sintering temperatures of up to 1400 degrees Celsius or higher.
Temperature uniformity: Ensure uniform temperature distribution inside the furnace to avoid uneven material properties caused by local overheating or undercooling. This is usually achieved through a reasonable layout of heating elements and advanced temperature control systems.

2. Atmosphere control
Atmosphere type: Select a sintering furnace that can introduce the required atmosphere according to the requirements of the sintering material. Common atmospheres include vacuum, inert gases such as nitrogen and argon, and reducing gases such as hydrogen.
Atmosphere purity and control accuracy: For materials with strict requirements for atmosphere purity, choose a sintering furnace with high-purity atmosphere input and precise control of atmosphere concentration.

3. Equipment structure and materials
Furnace material: Choose furnace materials with high temperature resistance, good insulation performance, and strong thermal stability, such as high-purity alumina polycrystalline fibers. This helps to reduce heat loss, improve energy efficiency, and maintain stability and uniformity of temperature inside the furnace.
Equipment structure: Choose sintering furnaces with box or tube structures based on the space limitations and operational convenience of the laboratory or production line. Compact box structure, suitable for places with limited space; The tubular structure is suitable for processing large-sized materials or materials that require extremely high temperature uniformity.

4. Control System and Operation
Intelligence and Automation: Choose sintering furnaces equipped with intelligent control systems, such as PLC automatic control and protection systems, as well as embedded microcomputer control systems. These systems can provide multiple operating modes such as manual, automatic, and constant temperature, and can achieve remote control and real-time tracking.
Operation interface: Select a sintering furnace with an intuitive and concise operation interface, such as a touch screen operation, to facilitate the setting and monitoring by operators.

5. Security performance
Multiple safety protection: Ensure that the sintering furnace has multiple safety protection measures, such as over temperature alarm and power-off protection function, leakage protection function, etc. These measures can automatically take protective measures in a timely manner when abnormal situations occur in the equipment, ensuring the safety of operators and equipment.
Sealing performance: Choose a sintering furnace with good sealing performance to prevent hot gas leakage and external air from entering, and maintain a stable atmosphere inside the furnace.

6. After sales service and customized service
After sales service: Choose manufacturers that provide comprehensive after-sales service to ensure timely resolution of equipment problems during use.
Customized services: Select manufacturers that can provide customized services based on specific process requirements and experimental conditions. This includes customization of furnace size, heating element type, gas flow control, temperature control accuracy, and other aspects.
