Micro Small SPS Plasma Sintering Furnace Advanced Material Sintering System

Product Overview

This spark plasma sintering furnace represents the forefront of rapid densification technology for advanced materials. By applying pulsed DC current directly through the powder compact within a conductive die, it generates internal resistive heating that activates sintering mechanisms instantaneously. This approach eliminates the slow heat transfer limitations of conventional radiation or convection furnaces, enabling heating rates as high as 800°C/min. The result is fully dense components with exceptional microstructural control achieved in remarkably short cycle times—often just a few minutes. Its compact, benchtop-friendly design makes it an excellent fit for modern research laboratories where space and efficiency are critical.

Designed to serve a wide spectrum of materials research, this furnace excels in processing refractory metals (tungsten, molybdenum, niobium), engineering ceramics (alumina, silicon carbide, boron carbide), cermets (WC-Co, TiC-Ni), and functional gradient materials. Typical applications include the development of new alloy compositions, production of small-scale ceramic prototypes, and rapid screening of novel composite formulations. Researchers in metallurgy, ceramics, nanotechnology, and energy materials value its ability to sinter powders into high-density bodies while minimizing grain growth—a challenge that plagues conventional sintering methods. The system’s versatility extends to emerging fields such as high-entropy alloys and thermoelectric materials.

Built for sustained performance in rigorous laboratory settings, the furnace incorporates a robust horizontal chamber with a side-opening door that permits easy loading and unloading of samples. Precision vacuum control achieves ultimate levels of 6.7×10⁻⁴ Pa, and the servo-electric press delivers up to 3 tons of force with fluctuations below ±150 N—critical for maintaining consistent density across runs. The integrated PLC with a touchscreen interface not only automates complex temperature-pressure-vacuum profiles but also provides comprehensive data logging with real-time curve visualization, historical archiving, and user-level access controls. These features, combined with a sturdy construction and proven component reliability, make this unit a trusted tool in academic and industrial R&D labs worldwide.

Key Features

• Rapid Joule Heating Technology: Pulsed DC current passes directly through the conductive die or sample, generating heat internally at the particle contacts. This eliminates thermal lag, resulting in heating rates up to 800°C/min and total sintering cycles as short as 2–5 minutes for many materials.
• High-Temperature Capability: The furnace achieves a maximum operating temperature of 2300°C, enabling the sintering of ultra-high-temperature ceramics (UHTCs), refractory metals, and composites that require extreme thermal conditions for densification.
• Ultra-Clean Vacuum Atmosphere: A cold-state ultimate vacuum of 6.7×10⁻⁴ Pa and a low pressure rise rate of just 2 Pa/h provide a pristine environment for processing reactive and high-purity materials, avoiding unwanted oxidation or contamination.
• Servo-Electric Precision Press: The press delivers up to 3 tons of axial force with closed-loop servo control. Pressure stability is maintained within ±150 N, and displacement accuracy is better than 0.01 mm, enabling precise densification and final part dimension control.
• Intelligent Process Automation: The touchscreen PLC controller allows programming of multistep profiles for temperature, pressure, and vacuum. All process data are recorded in real time and can be downloaded via USB for analysis, while recipe storage and user permissions enhance reproducibility and security.
• Ergonomic and Compact Design: The horizontal side-opening structure provides unobstructed access for sample handling while maintaining a small footprint. This design simplifies loading of dies and tooling, speeding up experimental turnaround.
• Dual Pressure Control Modes: Users can choose between force control and position control, adapting the press operation to the specific needs of the material—whether maintaining constant pressure or achieving a targeted displacement.
• Versatile Sample Geometry: With a press head diameter of 50 mm and a stroke of 0–60 mm, the system accommodates sample diameters from 8 to 15 mm and a variety of die heights, making it adaptable to many experimental setups.
• Exceptional Energy Efficiency: Direct resistive heating significantly reduces energy consumption compared to conventional furnaces, translating into lower operating costs and a smaller carbon footprint for the laboratory.
• Robust Safety Systems: Integrated interlocks, over-temperature alarms, and vacuum monitoring ensure safe operation even at maximum parameters, protecting both the operator and the equipment from potential mishaps.
