SPS Sintering System (SPS+Induction)
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 in the world today. It isa 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.
