Multi-Station Vacuum Molybdenum Wire Sintering Furnace

Product Overview

This multi-station vacuum molybdenum wire sintering furnace delivers exceptional high-temperature processing for advanced materials. By integrating a rugged top-lift chamber, high-purity molybdenum heating, and configurable vacuum capabilities, the system offers a versatile platform for sintering, annealing, and purification under precisely controlled atmospheres. Its compact, mobile design with built-in water cooling makes it an ideal choice for laboratories and pilot production lines seeking performance without infrastructure complexity.

Industries ranging from semiconductor ceramics to aerospace composites rely on this furnace for producing high-integrity components. It excels in processing oxide and non-oxide ceramics, hard metals, rare earth materials, and energy-related compounds. Whether developing new material formulations or scaling up to small production runs, the unit's reliable temperature uniformity and clean vacuum environment ensure consistent, repeatable outcomes.

Engineered for demanding round-the-clock operation, the furnace incorporates industrial-grade components, multi-zone PID control, and continuous data logging. These features not only guarantee accurate process execution but also provide full traceability for quality assurance. Combined with rapid vacuum pump-down and efficient cooling, the system minimizes cycle times while maintaining the structural and thermal stability needed for mission-critical applications.

Key Features

• Integrated Compact Design: The furnace incorporates all essential subsystems—heating, vacuum, cooling, and control—into a single, space-efficient chassis. Heavy-duty lockable casters allow the unit to be moved and repositioned safely without disassembly, making it ideal for labs and pilot lines with evolving layouts. This turnkey approach reduces installation time and cost.
• Top-Lift Loading Mechanism: A motorized lifting system raises the entire upper furnace body vertically, providing unobstructed access to the work chamber. The robust linear guide ensures smooth, stable motion, while the locking mechanism secures the hot zone during operation. This design simplifies loading of bulky or delicate workpieces and minimizes the risk of contaminating samples during charging.
• High-Temperature Molybdenum Heating: Molybdenum wire is used as the primary heating element due to its exceptional high-temperature strength and low vapor pressure, enabling sustained operation at 1600°C. The heating zones are precisely configured to deliver high thermal efficiency and fast ramp rates. This material choice is particularly suited for processing materials that demand a clean, non-reactive hot environment, especially when paired with high vacuum.
• Advanced PLC & Touchscreen Automation: A programmable logic controller matched with an intuitive color touchscreen provides a powerful yet user-friendly interface. Operators can store, edit, and recall up to dozens of sintering recipes directly from memory, reducing setup time and eliminating manual input errors. The system also supports multi-segment ramp/soak profiling to accommodate complex heating schedules tailored to specific material requirements.
• Real-Time Data Acquisition System: Critical process data—including temperature setpoints and actual values, vacuum pressure, and cycle timing—are continuously logged by the built-in data acquisition module. Users can start or stop recording at any time, reducing storage of unnecessary data. All records are accessible for on-screen review, trend analysis, and export via USB or network for full batch traceability and quality documentation.
• Multi-Zone Precision Heating: Three independent heating zones, powered by separate PID loops with dedicated thermocouple inputs, ensure exceptional temperature uniformity across the entire work volume. The controller precisely balances power outputs (5 kW / 10 kW / 5 kW) to maintain a temperature spread of ±3°C or better, even under dynamic conditions. This tight control is essential for achieving homogeneous material properties and high yields.
• Configurable Ultimate Vacuum: The vacuum system is modular, accommodating three pump configurations to match the application's cleanliness requirements. With a mechanical pump and Roots blower, ultimate vacuum reaches 6.67×10⁻² Pa; adding a diffusion pump achieves 6.67×10⁻³ Pa; and a molecular pump pushes performance to 5.0×10⁻⁴ Pa. This flexibility ensures the furnace can adapt from standard sintering to ultra-high purity processes.
• Integrated Closed-Loop Water Chiller: A self-contained water cooling system eliminates the need for facility plumbing modifications. The chiller maintains constant cooling water temperature and flow to protect the furnace structure and heating elements, while also reducing the thermal load on the vacuum seals. This integrated solution enhances system reliability and simplifies installation.
