In metalcasting, a core is a shaped body made of sand which forms the interior features of the casting. At Ferroloy, we use Green Diamond sand which is free of respirable crystalline Silica. The mold provides a space for the molten metal to go, while the core keeps the metal from filling the entire space.
Ferroloy uses resin coated sand utilizing automatic and manual hotbox core machines. Core coatings are utilized as needed.
