Product Overview

This advanced vacuum arc melting system integrates suction casting capability to produce high-purity alloys and bulk amorphous materials. Designed for laboratory-scale research and pilot production, it operates under inert argon protection to reach temperatures up to 3500°C, enabling the melting of high-melting-point metals such as titanium, zirconium, niobium, and their alloys. The compact desktop footprint makes it ideal for space-constrained materials science laboratories.
Engineered for demanding research environments, this furnace excels in the preparation of novel alloy compositions and metallic glasses. The water-cooled copper crucible with multiple stations allows simultaneous processing of several samples, while the integrated suction casting module directly shapes molten metal into rods for mechanical testing or further analysis. Its rapid vacuum and gas purging cycles significantly increase experimental throughput.
Constructed with industrial-grade components and safety features including over-temperature protection and a tinted viewing window, this unit ensures consistently reliable performance and operator safety across thousands of thermal cycles. Furthermore, the furnace's low thermal mass and efficient water cooling allow rapid cool-down between melts, enhancing productivity. Its intuitive controls and clear viewport make it suitable for both experienced technicians and student operators. The combination of precision vacuum control, robust cooling, and customizable configurations makes it a trusted tool for advanced metallurgical research.
Key Features
- Extreme Temperature Capability: Achieving up to 3500°C under high-purity argon, this furnace handles even the most refractory metals such as tungsten and tantalum. The inert atmosphere prevents oxidation, ensuring clean melts for sensitive alloys and enabling the study of high-temperature phase equilibria.
- Multi-Station Crucible Design: The copper hearth's five standard hemispherical stations allow simultaneous melting of multiple compositions, greatly increasing experimental throughput. Each station is numbered for easy sample tracking, and the entire hearth can be quickly swapped for different configurations. The central suction casting well directly forms 1‑6 mm diameter rods, eliminating secondary shaping steps and reducing material waste.
- Fast Cycle Times: A minimized vacuum chamber volume enables pump-down to high vacuum and argon backfill in under a minute, drastically reducing gas usage and enabling more melts per hour compared to larger systems. Operators can complete a full melt cycle in just minutes.
- Precision Vacuum Measurement: An integrated vacuum gauge provides continuous digital readout, ensuring that every melt starts from a consistent, contamination-free environment—key for reproducible results in both research and quality control.
- Water-Cooled Electrode & Crucible: Both the non-consumable electrode and the crucible are actively water-cooled, allowing sustained operation at maximum current without overheating and prolonging component life. This design also prevents crucible-driven contamination.
- Manual Electrode Lift: The electrode height adjustment is smooth and lockable, giving the operator fine control over arc length and melt pool dynamics for optimal stirring and chemical homogeneity. The precise positioning aids in reproducible arc ignition.
- Integrated Safety Features: Over-temperature and full-arc protection circuits automatically shut off power in unsafe conditions. The large tinted glass window filters harmful UV and IR radiation while maintaining a clear view of the melt zone, and an additional arc shield provides extra protection.
- Desktop Configuration: With overall dimensions of just 350×450×650 mm and single-phase power requirement, this unit fits easily on a standard lab bench, saving valuable floor space and simplifying installation. It requires no special building modifications.
- Rapid Solidification Control: The water-cooled copper hearth promotes fast cooling rates, preserving metastable phases and fine microstructures essential for amorphous and nanocrystalline alloy development. Cooling rates are adjustable via contact pressure and preheating.
- Flexible Customization: Beyond the standard configuration, customers can order custom crucible geometries, additional suction casting molds, alternative electrode materials (e.g., thoriated tungsten), and integration kits for glovebox operation, tailoring the system to specific research needs.
