· If a foundry is reclaiming sand, residual binder contributes to Loss On Ignition (LOI) at the mold/metal interface. LOI values consistently above 2% (prior to adding new binder to the sand) may contribute to gas defects. New sand additions can be made to reduce LOI if a reclamation system is performing optimally.

contact usFoundry Sands. Foundry sand (also known as casting sand) consists primarily of clean, uniformly sized, high-quality silica sand that is bonded to form moulds for ferrous (iron and steel) and nonferrous (copper, aluminium, brass) metal castings. The most common casting process used in the foundry industry is the sand cast system.
contact usFoundry Sand Types. According to the different binders, foundry sand used for moulding can be divided into green sand, water glass sand and resin sand. Clay sand is the mixture of natural silica sand, clay, additives and water. The clay used to make wet clay sand is bentonite clay. The compressive strength is generally 0.05 to 0.1 Mpa.
contact usSand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.
contact usThis varies with each foundry environment. Generally a starting point is 3% moisture.
