2021-2-1  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 binding material. This core sand mixture is blown into the core-box. Along with heated air, a vaporized ...

Sand Core Making Sand Casting Core Harrison

Core making is the process which forms the interior part of the casting. The mold provides a space for the molten metal to go, while the core keeps the metal from filling the entire space. Cores can be used to extend mold projections to create extra mold sections, or to block out and create negative drafts.
