Compact Vacuum Arc Melting System with Vacuum Casting Mold for 6mm Dia. Rod - EQ-SP-MSM208


In stock
Item Number: EQ-SP-MSM208
EQ-SP-MSM208 is a compact vacuum arc melting furnace with Vacuum Suction Casting mechanismSuch a unique feature can produce cast products ( 6mm Dia. rod shape, up to 30g) by drawing the molten metal into the bottom cold copper casting mold.  The sucking force applied results in a fast-moving and cause the rapid solidification of the melt which is ideal for reducing the shrinkage cavity defects. The machine also features a built-in mechanical manipulator for tilting and rotating metal ingots if the re-smelting process is needed. The SS304 chamber ensures a clean and healthy atmosphere suitable for the most demanding experimental requirements.  ( Sealing tube option added on Dec 12, 2018)

SPECIFICATIONS:
Features

Vacuum Suction Casting & Copper Crucible 
   
 

  • Vacuum suction casting 6mm Dia. rod, 30g max.
  • The sucking force is generated by evacuating the bottom cold copper casting mold. This results in rapid solidification of the melt which is ideal for reducing the shrinkage cavity defects 
  • One solenoid valve is built in for sucking operation
  • The water-cooled copper crucible has 7 cavities:
    • Central cavity (35mm dia. x 10mm depth) is for vacuum suction casting
    • The other six round cavities (25 mm Dia. × 8 mm depth) are reserved for metal alloy pellet preparation, max. 10g
  • Optional:  You may modify crucible in 70 mm Dia. to melt and casting  max.100 g ( Fe based alloy)

Application & Warning Notes


  • High purity 》4N Ar gas is required for the melting operation. 
  • A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 psi for safe operation. Click here to learn the installation of a gas regulator (Pic.1)
  • To avoid any damages to the mechanical pump or turbo pump, please install an Inline Particle Trap (maximum 1E-4 Torr vacuum with turbo pump) on the pump inlet port (Pic. 2)
  • Must Wear Welder Glass or Auto Welding Shade while observing the Arc while welding. 
  • An example of the system setup with a turbo pump can be on the left
  • The unit is designed for arc melting operation under tiny positive pressure or low vacuum (0.01 – 0.11 MPa pressure, or positive 0.01 MPa to negative 0.09 MPa pressure). Never operate the unit at high vacuum or high positive pressure!
  • During melting operation, never allow the electrode to touch the material or the copper crucible! Do not operate the mechanical manipulator during the melting process.
  • Option: The user may use a quartz tube shielding to effectively reduce the splash and spilling while arc melting. Please click pic 3 to watch the demo video.
