Skim Dams

 
Permatech is an industry leader in engineering and manufacturing precise parts for the ingot casting process. Our skim dams are cast from high-quality Permatech refractory materials and then kiln-fired, producing a hard, durable part to fit your desired dimensions. Permatech’s refractory compositions are designed specifically to be used in molten aluminum applications; their non-wetting properties allow for easy clean up.  

Permatech’s precast skim dams are denser than machined boards, allowing them to sit lower and eliminate the need to be weighted as board products. This results in a more efficient collection of the skim.
