Custom Designed Furnaces and Systems

For over 85 years, The Schaefer Group has developed custom aluminum furnaces for die casting, permanent mold and sand foundries. We specialize in electric, gas, and propane as well as combination fuel furnaces for melting, holding and transfer.

We also custom design launder systems, crucibles, filtration and degassing systems. Our re-line and repair services can retrofit existing furnaces as well. We have probably custom designed more molten metal delivery systems than anyone else in the world. Over 85 years of experience makes Schaefer Furnaces the experts in Profitably Casting Your Bottom Line!
