Water glass investment casting allows to produce steel castings from 0.05kg-80kgs. Water glass casting is cost effective compared to silica sol casting process.
Water glass casting components are mainly used for complex shaped parts. Applications of this technique are widely presented in the production of trailers, agricultural machinery and offshore industry. The water glass lost wax casting process provides a far superior surface finish and dimensional precision comparing to sand casting.
