Procedure for Core Making | Metal Casting

Ramming of Core Sand: The mixture of core sand is rammed into the core boxes. The surplus sand is stuck-off with strickles. The ramming may be done with machines or by manually. Step # 3. Venting of Core: ADVERTISEMENTS: Because a core is surrounded by molten metal from all sides during casting, gases have only a small area through which to escape. Therefore, good permeability is obtained by

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 amine gas catalyst is then purged thru the core sand. The
