Metamag Magnesium Melting Furnaces

Available for Hot or Cold Chamber

Hot Chamber features

  • Capable of small parts
  • Faster cycle times
  • Smaller melt bath due to “A” frame = reduced melt efficiency
  • Greater temperature swings due to submerged gooseneck
  • Metal bath limits 640°C due to gooseneck distortion and ring wear
  • Less air entrapment during shot
  • Furnace and preheater must be moved for gooseneck change
  • Time consuming. Plunger gooseneck changes
  • Difficult to run high temperature alloys
  • Low metal bath temperature = inter-metallic separation = sludge
  • formation in bottom of crucible
  • Inter-metallic particles cause heavy wear in plunger bone and piston ring
  • Perception that baffle in answer to prevention of inter-metallic's entering bore
  • Difficult to clean in front of gooseneck. More difficult in baffle used

Cold Chamber features

  • Capable of small parts multiple cavity
  • Slightly slower cycle time but more cavity = more parts
  • Larger melt bath = more stable bath temperature
  • No melt loss -metal runs through heated tube
  • Metal temperature can be taken up to 720°C
  • With proper metal temperature and transfer minimal air gas entrapment
  • No moving parts, pump can be changed without tools
  • Pump change 30 mins. / Tube change 15 minutes
  • Capable of running high temperature alloys
  • Pumping system is not affected by inter-metallic particles
  • 3x melt rate -therefore 1000# 1 hr or 3000# crucible
  • Easier to clean -no baffle

Small Parts Casting Solutions

Mini-Mag Furnaces are designed for small die cast machines 450 g.to 2 kg. The furnace is built without front corners allowing the furnace to be moved closer to the shot sleeve. This design keeps the transfer tube shorter minimizing plugging. The Mini-Mag System includes a low profile furnace shell with a shallow cast crucible, a short body MP4 Pump and a short transfer tube with a heated pouring spout.
