Core Making & Assembly
We have extensive expertise in designing, manufacturing and assembling complex sand cores. Our semi permanent mold castings contain both isocure and shell cores to produce highly complex geometries.
The isocur® process produces cores in a cold box, binding the sand together using a phenolic urethane resin. The sand and resin air-set and can be dipped in a coating material to produce an exceptional surface finish. We use various sands and aggregates to make simple cores as well as complex multi-core assemblies.
The shell core process pre-coats the sand with a resin before pouring it into a pre-heated core box. Heat is applied to the surface until a thin, hard shell is formed. We use shell cores to reduce the bulk and mass of a core within a casting, or for castings that require tight dimensional controls and good surface finish.
