Vacuum Atmospheric Furnace for metal materials

---

Over the past 10 years, SIMUWU vacuum furnace has produced vacuum sintering furnaces for cemented carbide, cermet, magnet, MIM products and special oxide ceramics. The sintering process agglomerates the particles into a coherent, predetermined solid structure. In this process, mass transport occurs in the atomic range. Single phase powder is sintered at 2 / 3 ~ 4 / 5 of the melting temperature, and multi-phase powder (mixture) is sintered near the solid line of the lowest melting phase.

Vacuum Atmospheric Sintering Process
The sintering process is carried out under the action of vacuum or shielding gas at a suitable temperature. A definite, repeatable sintering atmosphere without atmospheric oxygen is very important. At a certain pressure and temperature, the process gas feed during sintering with argon, nitrogen, hydrogen, methane, carbon dioxide and other gases may affect the structure and chemical composition of the workpiece.

Application of vacuum atmospheric furnace
Copper tungsten alloy, silicon carbide products, tungsten molybdenum and other metal materials vacuum high temperature sintering, precious metal and semi precious metal vacuum investment casting, carburizing, gem and diamond processing.

vacuum atmospheric furnace characteristics

Reasonable vacuum unit is adopted to meet the requirements of vacuum sintering process.

The intelligent temperature controller can be installed, and the temperature rise curve can be set freely for 100 times. The temperature control accuracy is high, and the temperature rise can be conducted according to the program.

High efficiency medium frequency power supply and induction coil are adopted, with high output power and fast temperature rise.

High temperature (900 C to 3600 C).

Even at temperature, you can transfer hydrogen, nitrogen and argon through the mass flow controller in the furnace.
