NEXAND is special artificial sand developed by Japanese leading foundry sand supplier Yamakawa Sangyo, Amagasaki, Japan, and is used with silica sand to improve quality and reduce costs. Leading manufacturers see it as an investment in their process quality. This unique product was specially designed and developed for foundry professionals facing casting defects such as veining and deformation, which are usually caused by thermal expansion of silica sand.
Since NEXAND is mainly composed of enstatite and forsterite in the form of MgO and SiO2, it has superior hardness and low thermal expansion properties compared to silica sand. Since the grain surface of NEXAND is carefully polished and cleaned through a special treatment process, very few dust particles adhere to grains.
A mixture of about 30% NEXAND with silica sand dramatically improves casting quality and production rates, resulting in precision casting while reducing scrap rates and minimizing costs of correcting defects.
Due to its low thermal expansion property, NEXAND is used to prevent casting defects such as veining and shell core deformation.
NEXAND has already been proven and widely adopted by top-rated Japanese foundries, especially where a shell core with an intricate design is required.
NEXAND is a real money-saver for your foundry operations. It is an investment in your process quality.
