The moulds and cores 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.
Foseco offer a broad range of organic and inorganic mould and core binder systems. Organic binders are almost exclusively synthetic resins, which are cured by the addition of a separate hardener or catalyst. Inorganic binders are based on sodium silicates which have been optimised to accommodate the varying casting processes, thus guaranteeing best decomposition.
