Mini Arc vacuum Melting Furnace is a Compact Vacuum Arc Melting Furnace with non-consumable tungsten electrode and water cooled copper crucibles. Integrated mechanical manipulator can repeatedly tilt/rotate multiple metal ingots for remelting process. It is an excellent tool for smelting metal alloys with elevated mechanical homogeneity under protective gas environment.
Mini Arc vacuum Melting Furnace feature:
induction melting machine can be used for the melting of steel, stainless steel, brass, aluminum, gold, silver and so on
Arc Melting Furnace specificaitons:
| Features | Φ120mm front door for easy sample loading/unloading
A tinted observation window is installed on the front for instant monitoring melting process. Water cooled vacuum chamber(φ300mm × 320mmH), cold copper crucible Electrode position (height) adjustment via hand wheel turning Integrated mechanical manipulator made of stainless steel 1Cr13 can multiple metal ingots without breaking the vacuum Water cooled copper hearth allow smelting multiple samples without |
| Vacuum Pressure
Gauge |
Please select the anti-corrosive capacitance diaphragm gauge or mechanical vacuum pressure
gauge from option bar. Digital pressure gauge is used for vacuum chamber Mechanical pressure gauge is used when continuous flow of inert gas |

| Vacuum Chamber
&Copper Hearth |
Vacuum chamber: Φ200mm×350mm, made of stainless steel with water cooling jacketWater cold copper hearth with 7 crucibles of 25mm dia.x 8 mm depth ( see the first pic on left )Solidified sample is about 20 mm half-round button in max. and sample weight is depended on material density. Customized copper hearth is available upon request ( see the second pic on left ) Sample weight for each crucible can be estimated as: W (g) = 2/3 π r3 d |
| Electrode | 4 mm dia. Tungsten electrode with water cooling
Top hand wheel can move electrode cycle, upward and downward ( max. 30 mm) sample in one batch |
| Water Chiller
& Gas (Optional) |
Water cooling is required ( not included ) for its chamber, copper mold and electrode. Please consider to use the KJ-5000 recirculating water chiller. High purity Ar gas is required ( not included ). You may use 5% H2 + 95% Ar gas reduce oxidation |
| Vacuum Pump
(Optional) |
Vacuum Level is dependent on the vacuum pump used:
1E-3mbar via mechanical/roughing pump (please click underline to view 1E-5mbar via turbo pump. We strongly recommend you consider Turbo-molecular Vacuum Pump Station for high quality melting. |
