SP-MSM-800A Arc Melting System with Vacuum Chamber, Water Cooling, Electromagnetic Stirring, and Casting Function up to 500g
The SP-MSM-800A is engineered for researchers requiring precise melting and casting of metal alloys under controlled vacuum conditions. It facilitates the study and production of advanced alloys by combining a high-vacuum environment with arc melting and casting capabilities. The system’s water-cooled stainless steel chamber maintains vacuum levels down to 5×10-6 torr, minimizing contamination and oxidation during processing.
This system integrates a powerful arc melting power supply with a motor-assisted tungsten electrode capable of a 100 mm vertical stroke, enabling contactless arc ignition and stable melting. The built-in wobble stick allows sample flipping inside the vacuum chamber without breaking vacuum, enhancing process control and sample uniformity. Multiple interchangeable copper hearths support melting capacities from 100 g to 1000 g, with options for electromagnetic stirring and vacuum casting molds to tailor the process to specific research needs.

Typical Applications
The SP-MSM-800A is suited for research and development of advanced metal alloys, including iron and steel-based materials. It supports vacuum arc melting, electromagnetic stirring for homogeneity, and vacuum casting for producing high-quality ingots and samples for metallurgical analysis, materials science, and alloy design.
Configuration & Operating Notes
The system requires an external water chiller for cooling, recommended models include the KJ6200 or equivalent. High-purity inert gas supply is necessary for operation but not supplied. Optional upgrades include higher power supplies, vacuum system components, and customized hearth cavities or casting molds. Operators should ensure proper vacuum sealing and cooling water flow to maintain system performance and safety.
