Product Details

Spark Plasma Sintering (SPS) is a new material preparation technology with fast heating, short sintering time, high density of materials, controllable impressed pressure and sintering atmosphere. Compared with traditional technology, it has many advantages and characteristics such as fast, low temperature, energy saving, environmental protection, etc., and mainly uses discharge plasma for sintering.
DC Sintering Technology (DCS) is a major breakthrough in SPS technology. As an advanced sintering process, DC sintering can continuously provide discharge sparks to further improve sintering efficiency and quality. Therefore, this technology can be used for rapid solid phase sintering of various high density and high uniformity materials. Moreover, the DCS sintering furnace power supply design is more compact, and can be applied to the sintering of large-sized workpiece samples as well as small multi-cavity component sample preparation. The DCS system can produce better materials than traditional sintering equipment, while having shorter experimental time and experimental cost.
DC spark plasma sintering furnace advantages:
1. DC power supply, simple system, high stability
2. Better material performance controllability
3. Shorter processing time
4. Lower experimental cost
5. Lower equipment costs
