Miniature Non Consumable Vacuum Arc Furnace for Laboratory Alloy Melting and High Temperature Material Synthesis

Product Overview

This laboratory-scale desktop system is designed for high-precision, non-consumable vacuum arc melting, offering material scientists a versatile tool for synthesising high-purity metallic samples and alloy formulations. Operating under vacuum or high-purity inert gas backfill, the equipment utilizes a high-energy electric arc to reach extreme temperatures rapidly, facilitating the processing of refractory metals without crucible contamination.

The unit is particularly suited for academic research laboratories, industrial research and development centers, and metallurgy laboratories looking to prepare small-scale test specimens. Its compact footprint and rapid processing cycles make it ideal for quick-turnaround experimental runs and high-throughput material screening.

With its robust construction, advanced insulation sealing, and integrated safety interlocks, this system ensures highly repeatable thermal cycles and reliable operation. Researchers can confidently execute delicate melting procedures under demanding high-current conditions, knowing the structural integrity of the furnace chamber is maintained.

Key Features

• Movable Water-Cooled Copper Electrode: The unit features a highly maneuverable electrode mounted on a flexible bellows assembly, allowing operators to manually reposition the arc over different crucible cavities within a single cycle. This multi-sample design eliminates the need to break vacuum between runs, significantly accelerating experimental throughput and enhancing process efficiency.
• Optimized Desktop Space-Saving Geometry: Engineered specifically for cleanrooms and space-constrained research environments, the system integrates the furnace chamber, control panel, and power supply into a single, compact benchtop framework. This design minimizes the laboratory footprint while maintaining full industrial-grade capability.
• Ultra-High Temperature Melting Capacity: Leveraging a customized, high-density arc melting power source, the system is capable of instantly generating temperatures up to 3500°C. This allows researchers to effortlessly melt and alloy refractory metals such as tungsten, tantalum, molybdenum, and niobium without requiring oversized industrial installations.
• High-Vacuum Compact Chamber Design: The low-volume stainless steel vacuum chamber is engineered for rapid evacuation and low inert gas consumption. By minimizing the chamber volume, the system achieves target vacuum levels quickly and reduces the volume of high-purity argon gas required for purging and backfilling.
• Ergonomic Front-Access Loading Door: The vacuum chamber is configured with a convenient, wide-opening front door available in left-swing or right-swing variations. This layout provides direct and unobstructed access to the crucible hearth, simplifying sample loading, cleaning, and routine chamber maintenance.
• Advanced Safety Insulation and Mounting: The bottom-mounted water-cooled copper crucible is secured directly to the furnace base with high-dielectric insulation seals. This design prevents electrical leakage, protects the structural integrity of the stainless steel chamber, and ensures complete operator safety during high-current operations.
• Tailored Vacuum System Integration: Depending on the specific application requirements, the system can be configured with various vacuum packages. Options range from standard rotary vane pumps for basic inert atmosphere melting to diffusion or turbo-molecular pump stations for high-vacuum, low-contamination alloy synthesis.

Applications

The versatility of this vacuum arc melting system makes it an essential tool for various advanced materials engineering and metallurgical research applications. By isolating the melt pool from external atmosphere and crucible contaminants, it enables researchers to study pure material characteristics.

Technical Specifications

This system is engineered to provide precise control over the electric arc melting process. The table below outlines the comprehensive mechanical, electrical, and vacuum specifications for the TU-DH02 system, helping procurement teams and laboratory managers select the correct configurations for their research facility.

Please note that the vacuum level of the TU-DH02 depends heavily on the selected pumping configuration. While a basic mechanical pump is suitable for inert gas purging, high-vacuum configurations utilize high-vacuum diffusion or turbomolecular systems to reach deep vacuum levels, preventing oxidation during the critical arc melting phase.
