Spark Plasma Sintering Furnace (SPS) (20 t, 1600°C)
Category: Hot-press sintering
Overview
Technical Specifications
This product is a high-end sintering system specifically designed for scientific research and small-batch production, focusing on the rapid fabrication of materials with high density and high purity. With “high efficiency, precision, energy savings, and safety” as its core design principles, it is ideally suited for use in universities, research institutes, and specialized materials companies, providing efficient and reliable hardware support for the sintering and forming of metals, ceramics, composites, and other materials—balancing research-grade accuracy with practical production applications.
Key features:
1. Cutting-Edge Core Technology: Leveraging the core technology of spark plasma sintering (SPS), combined with 20-ton high-pressure application and precise temperature control at 1,600°C, this process enables rapid heating and fast sintering, significantly shortening the sintering cycle—improving efficiency by 30% to 50% compared with conventional sintering equipment—while minimizing material oxidation to ensure product purity and performance.
2. Precise Temperature and Pressure Control: Equipped with a high-precision temperature control and pressure regulation system, the furnace maintains a stable temperature within 1600°C and precisely controls pressure up to 20 tons. The temperature field is uniform and the pressure is stable, effectively preventing cracking, deformation, and compositional inhomogeneity during sintering, thereby ensuring consistent quality of sintered parts.
3. Broad Compatibility: The system is compatible with a wide range of materials, including metals, ceramics, carbon-based materials, and composites, and supports both single-target and multi-target sintering as well as multilayer composite sintering. It can meet the needs of material property testing and process development in research settings, while also accommodating small-batch production of specialty materials for industrial applications.
4. Convenient and Efficient Operation: Features an integrated user interface with pre-set sintering process parameters and support for custom process profiles. It enables real-time monitoring of critical parameters such as sintering temperature, pressure, and vacuum level, ensuring simple operation that allows even beginners to quickly get up to speed and lowering the barrier to entry for both experimental research and production.
5. Safe, Stable, and Reliable: The furnace body is constructed from high-temperature and corrosion-resistant materials and features a vacuum-sealed design that effectively isolates air and prevents oxidation. It is equipped with multiple safety protection devices for over-temperature, over-pressure, and electrical leakage, operates with low noise, requires minimal maintenance, and is suitable for both laboratory and small-scale production environments.
