MinSand has several properties that make the product quite unique on the market:

Flow Characteristics

The spherical particle shape significantly improves the flowability of the sand/binder mixture allowing cores of complex shapes to be blown when compared to alternative angular sands.

Thermal Expansion

MinSand has a very low thermal expansion rate, which enables castings to be produced with a high degree of dimensional accuracy compared to mould and cores produced from alternative sands. This is eminently suitable for automotive cylinder blocks and heads.

MinSand binder quantities/strength

The spherical nature results in a reduced surface area, enabling cores and moulds to be produced using lower resin additions. The mixed sand costs are reduced accordingly because of the lower resin demand.

Resin Systems

LKAB Minerals’product is compatible with resin systems, including pre-coated shell moulding sands. The sand grains have a very smooth surface that is easily resin coated.
