Small Vacuum Molybdenum Wire Sintering Furnace

Product Overview

This compact vacuum sintering furnace is engineered for precision high-temperature processing in laboratory and R&D environments. Featuring molybdenum wire heating elements and a high-integrity vacuum chamber, it provides contamination-free sintering for a wide range of advanced materials. The unit’s bottom-loading configuration and integrated cooling system simplify operation, while the rugged construction ensures long-term reliability.

Primary applications include sintering of technical ceramics such as alumina, zirconia, and silicon carbide, as well as hardmetal alloys and cermets. It also supports metal annealing, brazing, and degassing under high vacuum, and quartz dehydroxylation for optical and semiconductor uses. Its broad capability makes it an indispensable tool for materials science labs, universities, and industrial R&D centers.

Built with precision components and rigorous quality control, this furnace delivers consistent results even under extreme conditions. Advanced PID control maintains temperature stability, and the vacuum system achieves low ultimate pressures essential for high-purity processing. User-friendly automation, data logging, and a modular design ensure reproducibility and ease of maintenance, meeting the needs of modern research environments.

Key Features

• Compact Integrated Design with Mobility: The furnace’s space-saving architecture consolidates the vacuum chamber, heater, controls, and pumping system into a single robust enclosure. Built-in heavy-duty swivel casters with locking brakes enable smooth movement and secure positioning, ideal for laboratories where equipment must be shared or reconfigured frequently.
• Bottom Lift Loading Mechanism: A motorized ball-screw lift gently raises the hearth platform into the heating zone, ensuring smooth and repeatable sample placement. This design eliminates the need for manual reaching into the hot chamber, improving safety and ergonomics while accommodating taller crucibles or complex fixtures.
• Advanced Touchscreen PLC Control: A high-resolution color touchscreen provides real-time visualization of temperature, vacuum level, and process status. The PLC controller supports multi-segment temperature and pressure profiles with ramp/soak programming, allowing precise execution of complex thermal cycles.
• Extensive Process Storage and Recall: The controller memory can store up to 50 custom sintering recipes, each with configurable parameters. Operators can easily create, edit, copy, and delete programs directly on the screen or transfer them via USB for backup and remote editing, drastically reducing setup time and transcription errors.
• Real-Time Data Logging and Export: Continuous data capture of temperature, vacuum, and time stamps with user-defined logging intervals. Data is stored on an internal flash drive and can be exported as CSV files for analysis, reporting, and compliance with laboratory documentation standards.
• High-Performance Graphite Heating Element: The heating assembly features a robust graphite element capable of sustaining temperatures above 2300°C, surrounded by molybdenum wire insulation for excellent heat distribution. This design offers rapid heating rates, low thermal mass, and long service life even under aggressive cycling conditions.
• Precise Temperature Control: Closed-loop PID temperature regulation with a dedicated thermocouple achieves control accuracy of ±1°C over the entire operating range. This stability is critical for achieving uniform material densification and minimizing thermal gradients that cause cracking or warping in sensitive parts.
• Built-In Closed-Loop Water Chiller: An integrated water chiller maintains constant cooling water temperature, protecting critical seals and vacuum pump components. This self-contained system avoids the need for facility chilled water lines and ensures reliable cooling during extended high-temperature runs.
• Versatile Atmosphere Management: The vacuum system includes a two-stage rotary vane pump and a high-vacuum diffusion pump to achieve ultimate pressures in the 10⁻³ Pa range. A mass flow controller–based gas inlet permits precise backfill of argon, nitrogen, or forming gas up to 0.05 MPa, enabling controlled sintering atmospheres.
• Safety and Diagnostics: Comprehensive safety features include over-temperature alarm, cooling water flow interlock, vacuum gauge interlock, and emergency stop. Fault conditions are displayed in plain text on the touchscreen, facilitating rapid troubleshooting by operators.
