SP-MSM360 32-Station Automatic Arc Melting System for High-Throughput Alloy Research with CNC 3-Axis Positioning and Ultra-Clean Glove Box
The SP-MSM360 is engineered to address the demands of high-throughput alloy development and phase diagram research by enabling simultaneous arc melting of up to 32 small alloy specimens. This system is particularly suited for research on new-generation high-entropy alloys and other multi-principal element materials, facilitating efficient batch processing under rigorously controlled environmental conditions.
Central to the system is a gas-controlled glove box that maintains ultra-low moisture and oxygen levels (<1 ppm), ensuring sample purity and preventing contamination. The arc melting process is automated via a CNC three-axis (X, Y, Z) stage that precisely positions a 4 mm tungsten electrode over the water-cooled copper crucible cavities. The electrode can be programmed for stirring motions to promote uniform melting and alloy homogeneity.
Key Features
- Automatic arc melting of 32 samples per batch using two 16-cavity water-cooled copper crucibles.
- Ultra-clean glove box environment with <1 ppm H2O and O2 levels for contamination-free processing.
- CNC-controlled 3-axis positioning of tungsten electrode with programmable stirring motion for uniform melting.
- Powerful arc melting power supply supporting stable ignition and operation at up to 185 A DC output.
- Manual arc melting option available via handheld stinger with KF40 feedthrough.
- Vacuum dust removal fixture and crucible grid cover minimize cross-contamination during melting.
- Integrated 16 L/min recirculating water chiller for cooling crucibles and electrode.

Typical Applications
The SP-MSM360 is ideal for rapid synthesis and screening of novel alloy compositions, including high-entropy alloys and multi-principal element systems. It supports phase diagram development and materials genome initiative (MGI) research by enabling batch processing of multiple small samples under controlled atmospheres.
Configuration & Operating Notes
The system includes a glove box with integrated H2O and O2 purification, two water-cooled copper crucibles, CNC-controlled tungsten electrode assembly, handheld arc melting stinger, and a recirculating water chiller. Optional vacuum dust removal and crucible grid covers help prevent cross-contamination. Users must avoid contact between the tungsten electrode tip and samples or crucible during operation. Regular regeneration of the purification system and replacement of consumable oxygen sensors are required to maintain performance.
