Foseco’s sand mould and core coating products help foundry operators achieve the best available casting surface finishes at the highest possible level of operational efficiency. Because we focus our efforts on advanced rheology and suspension technologies, and use only the highest quality refractory components, Foseco’s sand coating products provide “as-cast” excellent surface performance, particularly in critical applications. They are also noted in the industry for their ease of use and process productivity.
Foseco’s Sand Coating products provide:
Refractory coatings provide a protective barrier between the molten metal and the mould or core substrate. It is this barrier that is of paramount importance in ensuring the integrity of the as-cast surface of the finished component, and hence inconsistencies within the coating structure or the application method will be reflected in the surface quality of the component.
The improvement in as-cast surface finish, can be as basic as the removal of sand grain definition, but more often it is the reduction and elimination of a number of casting defects:
By careful selection of refractory fillers, rheology and the application characteristics required by the foundry, Foseco coatings are designed to deposit the correct coating structure onto a given substrate, to ensure cast surface integrity. The range of products have been specifically engineered so that they can be applied by dipping, flow coating, brushing, swabbing and spraying.
Water and solvent based coatings with specially selected refractory materials to ensure full protection against metal penetration and burn-on defects.
Electrostatic coatings, mould hardeners, and coatings for fill mould, lost foam, spun pipe, refractories and tools.
Automated, density controlled coating preparation equipment for optimum wet layer thickness application.
A selection of containers and equipment for the transport, storage and application of coatings products.
