Metamag Magnesium Melting Furnaces
Available for Hot or Cold Chamber
- Built to last element design with 2 year warranty
- Metamag magnesium furnace technology is improved to reflect the higher temperature required to melt magnesium at a consistent point
- Contoured elements heat around the length of crucible, as well as the bottom
- Gas fired or electric
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.
