Below is a list of Industrial Furnaces manufacturers from Suncook, New Hampshire. Industrial furnaces are enclosed structures that contain high heat chambers. Compared to industrial ovens, they provide much higher temperatures and therefore are mostly used on materials with high melting points. They are found in glass fabrication, steel service centers, foundries, forgeries, metal recycling plants and any metallurgy application involving the use of heat to alter, improve, fabricate or form metals like steel, titanium and aluminum, alloys, glass, composite materials and some plastics.
