Analysis of Chemically Bonded Sand Used for Molding in Foundry
Majority sand molds and cores are made of silica sand, because it is the most easily available molding component It has lower cost of tooling, broad scope of metals and fewer limitations in part geometry, especially when compared to permanent mold processes [2] [10] Fig 1 The Classification of Sand Molds by Molding Technology II SAND MOLDSThe silica sand can be specified according to the size (small, medium and large silica sand grain) and the shape (angular, subangular and rounded) Moisture The amount of moisture content in the molding sand varies generally between 2 to 8 percentMOLDING MATERIAL uobabyloneduiqIt is made of silica sand and clay, without the addition of used sand Different forms of carbon are used to prevent the metal from burning into the sand The layer of molding sand usually ranges from 20 to 30 mm It is about 10 to 15 percent of the whole molding sand used in the foundry5 Molding and Core sands Malnad College of Engineering

Silica Free Mold Core Making Sand Midvale Industries
Green Diamond Foundry Sand is available in Ferrous and NonFerrous Foundry grade sands and is the ideal silica free replacement for olivine and silica sands for molding and coremaking Benefits: Complies with PEL Limits; Green Diamond’s durability is greater than both olivine and western silica sands meaning less breakdown and dustGreen Diamond sand is, technically, an Olivine sand, that has been processed by melting and then granulated by quenching in water It has the same main advantages that the natural Olivine has, which are no free silica and a low thermal expansion, which minimizes, or eliminates expansion defects, and reacts basic, rather than acidic like silica sandGreen Diamond Sand Midvale Industries
