S300 Spark Plasma Sintering Furnace

The spark plasma sintering system is one of the most advanced sintering systems in the world today. It is a new type of rapid sintering technology that applies pulse current and axial pressure between two electrodes for powder sintering densification. It has the distinctive characteristics of fast heating rate, short sintering time, controllable structure, energy saving and environmental protection. It can be used to prepare metal materials, ceramic materials, composite materials, nano block materials, amorphous block materials, gradient materials.

Technical Data

Rapid heating and cooling, greatly shortening production time and reducing production costs (heating rate can reach 100 ~ 200℃ / min).

1Self-developed high efficiency and energy saving power supply

Adopting self-developed pulse frequency conversion DC power supply, The current output is stable and the power consumption is greatly reduced, energy saving and environmental protection.

2Precised pressure control system

Servo valve is used to control the pressure output of the hydraulic cylinder, and the control accuracy can reach 1/1000.

Thermocouple and two-color infrared instrument are used to measure the temperature.

3Advanced automatic control and reliable safety interlock

Adopting computer to realize automatic control of temperature and action process, PLC safety interlock. It has sound and light alarm and interlock function such as over-pressure, over-temperature and high water temperature.
