Core & Mould Additives

Moulds and cores used in foundry must be hard enough to withstand the casting process, but must breakdown after solidification so that the casting can be easily removed from the mould.

FRM has produced specific additives of cores and moulds for different foundries for many years.

FRM core and mould additives are divided into four main types:

  • Silicate binders

binders are based on sodium silicates that have been optimised to accommodate the varying casting processes, thus guaranteeing best decomposition.

 

  • Mould and core adhesive

glues and sealants and self-setting or air drying adhesives.

 

  • Liquid breakdown agent for CO2 process

Additives for Sodium Silicate/sand mixture to improve breakdown of the sand compact after casting

 

  • Liquid and powder parting agent for shell sand systems

Either liquid or powder form have their own advantages.  They cause Mould and core materials part easily and cleanly from the pattern or box and also from each other.
