Key Features

• Ultra-High Temperature Performance: Reaches a maximum temperature of 2300°C with a rated operating range from ambient to 2200°C. This capability enables sintering of advanced materials such as tungsten, molybdenum, and ceramic matrix composites that require extreme heat.
• Precision Temperature Control: Utilizes an advanced PID controller with both thermocouple and infrared temperature sensors, achieving ±1°C accuracy across the heating zone. This dual-measurement approach ensures reliable process repeatability and uniform material properties.
• Superior Vacuum Integrity: Achieves a cold-state ultimate vacuum level of 6.67×10⁻³ Pa after bake-out, producing a clean environment free from oxygen and moisture. The vacuum system prevents oxidation and contamination during sintering, resulting in high-quality sample output.
• Integrated Hydrogen Safety System: Equipped with an automatic ignition device for hydrogen tail gas, the unit eliminates the risk of explosive gas accumulation. This feature makes it safe for hydrogen-atmosphere sintering of metals that require a reducing environment.
• Versatile Atmosphere Control: Supports a wide range of process gases including argon, nitrogen, and hydrogen, with a filling pressure of up to 0.05 MPa. The system allows precise atmosphere regulation to tailor sintered material properties.
• Compact and Efficient Work Zone: The work zone of Φ80×80 mm (D×H) is optimized for small sample sizes, minimizing energy consumption while delivering uniform heating. This compact design is perfect for labs with limited space.
• Intuitive PLC Touchscreen HMI: The programmable logic controller with a user-friendly touchscreen interface provides real-time monitoring of temperature, vacuum, and gas flow. It allows users to create, store, and recall multi-step recipes, and includes data export via USB for traceability.
• Bottom-Loading Convenience: The bottom lift mechanism simplifies sample placement and retrieval, especially for delicate or oddly shaped parts. The design maintains vacuum seal integrity and reduces particle contamination.
• Durable Graphite Hot Zone: The graphite heating elements and insulation provide excellent thermal stability and resistance to thermal shock, ensuring long service life even under rapid heating and cooling cycles.
• Enhanced Safety Features: In addition to hydrogen ignition, the system includes over-temperature protection, vacuum loss alarm, and emergency stop functions. These safeguards protect both the operator and the equipment during unattended operation.
