S3 SPS Sintering System

Fast Heating Rate / Short Sintering Time / Controllable Organizational Structure /Energy-saving and Environmental Protection

The SPS  (Spark Plasma Sintering) DCS discharge plasma sintering system is one ofthe most advanced sintering systems intheworldtoday. It is a new rapid sintering technology that applies pulse current and axial pressure between two electrodesto densify powder sintering. It has distinct characteristics such as fast heating rate, short sintering time, controllable organizational structure, energy conservation and environmental protection. It can be used to prepare metal materials, ceramic materials, composite materials, as well as nano bulk materials, amorphous bulk materials, gradient materials, etc.

Due to the discharge effect caused by the application of DC pulse current during the SPS process, there are several unique characteristics:

It can quickly heat up and cool down, significantly shorten production time, and reduce production costs (with a heating rate of up to 200°C/min);

Low sintering temperature (compared to hot pressing sintering, the sintering temperature can be further reduced);

It has a unique purification and activation effect (Eliminating the adsorption of gas on the surface of powder particles and breaking through the oxide film), easily achieving the sintering of di˝cult to sinter materials and multi-element materials;

Compared to traditional sintering processes, materials with more uniform, denser, and smaller grain sizes can be obtained in a shorter time;

Compared to traditional sintering processes, it can significantly save electricity; Adopting our professional DC pulse power supply technology, it has fast sintering speed, stable and reliable performance, and good energy-saving e˜ect; High pressure accuracy: Adopting a servo pressure control system, the pressure accuracy is ±3‰;

Using dual temperature sensors for temperature measurement, K-type thermocouples for temperature control in the low temperature range, and infrared temperature control in the high temperature range;

Good safety performance: Adopting HMI+PLC+PID pressure sensing control, safe and reliable;

Good sealing performance: Dynamic pressure heads are sealed with corrugated pipes to ensure no air leakage.
