Sand Core Dryers
Sand molds and cores are coated with a refractory wash after being formed. The refractory wash is a water or solvent based liquid, magnesite talc or graphite solids. The wash is applied to the mold, providing a better surface finish on the casting and protecting the sand mold from the heat as it enters the mold cavity. The molds and cores, after washed, are dried in a conveyor oven before casting. These ovens are often referred to as sand core dryers, mold dryers, or core drying ovens.
