Due to the increasing complexity of component geometries,the ongoing development of materials with
sophisticated casting properties, and customers’ increasing quality requirements,classic mold materials used
today (quartz, chromite sand, and zircon) are often pushed to the limits. This results in penetration or sintered
cores and castings, poor surfacequality, and a higher rejection rate.
The development of synthetic CERAMIC SAND as a special molding material for use in iron and steel
casting has been proven to address these issues. A mold material with almost perfectly spherical grains
results in ideal flow behavior during core production. The mineralization of highly thermally stressed core parts
can bepermanently avoided by using CERAMIC SAND molding material.
The required surface quality is almost always achieved without additional grinding. CERAMIC SAND mold
material consists of sand grains that have an almost perfect spherical shape.
Some of its key featuressuch as high gas permeability, exceptional flow behavior,
and substantially reduced binder requirement are attributed tothis characteristic.
CERAMIC SAND can be used with all common binder systems and is compatible with both thermal and
mechanical reclamation systems. Compared to the use of traditional raw materials for molds, binder usage
can be reduced by up to 60%, dependingon the binder system type.
