Binders are a big part of the core sand making process. Green sand cores are made from standard damp molding sand mixtures, and a binder, like dextrin. Cores of this type are very fragile and can be made with an arbor or interior

Core Making for Sand and Permanent Mold Castings

We produce sand cores in house using two core making processes: The Isocure Core Making Process. Isocure cores are produced using a "cold box" core making process. That is, in the Isocure coring making process, no heat is applied to the core box. An Isocure Core is produced using silica sand mixed with a phenolic urethane resin used as a

Thermal expansion defects, i.e. veining, are reduced in iron, steel, and nonferrous castings by adding a lithia containing material in a sufficient amount to the silica sand mold to provide about 0.001% to about 2.0% of lithia. The addition of lithia is accomplished by adding lithium bearing minerals such as α spodumene, amblygonite, montebrasite, petalite, lepidolite, zinnwaldite,
