Foundry Sand User Guidelines RMRC
Foundry sand is high-quality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings. The metal casting industry annually uses an estimated 100 million tons of foundry sand for production. Over time, foundry sands physically degrade until they are no longer suitable for molds. Consequently, 9DIMENSIONAL CAPABILITIES OF STEEL CASTINGS,guidelines that influence the recommended geometry of steel castings are discussed in “Steel Casting Design”. 1 2.1 Draft (Taper) Allowances Draft should be designated on the casting drawing in consultation with the casting producer— typically in a drawing note. The draft angle selected should be no less than can be tolerated in the design.
