Core Making Procedures

Depending on the requirements, several anorganic and organic binders and different core making processes can be used.

The options are:

  • Cold-Box
  • Croning
  • Furan
  • Resol-CO2
  • Sodiumsilicate-CO2

Generally core volumes are between 2.5 and 80 l (0.6 and 20 gal). For hand-made cores, there are practically no upper limits. Core and mold wash can be used to improve the surface finish of the castings and to modify the heat transfer conditions between metal and mold.
