Our process begins by selecting from a variety of iron blends to meet each casting’s unique specification. Large furnaces melt the iron and stay at temperatures ranging from 2,600 to 2,800 degrees Fahrenheit. Computerized systems constantly monitor temperature. As the castings cool, they enter a shakeout process in which the molds are shaken off and the sand is recycled for reuse. When castings get below about 140 degrees, they are cleaned and finished.
Melting Iron the Poitras Way
It all starts with turning up the heat. Iron is melted using our four electric induction furnaces. Our foundry in Lislet, QC has electric induction-melt furnaces, which use the magnetic properties of iron to create friction and heat. These furnaces also store liquid iron. Electric induction melting is the most cost efficient type of melting process. In addition, it is very environmentally friendly, using only electricity.
