• 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

• 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 if baffle used.

• 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
