Abstract

241,773. Werner, K. Jan. 24, 1925. Moulds; lubricating; coating moulds with powdered material-Sand moulds for making smooth casts in plaster, cement, casein, &c. are dusted with powdered resin, pitch, or sulphur sublimate and the powder is liquefied so as to flow and fill the crevices by heating or by spraying with a solvent such as ether or methylated spirit. The process is particularly suitable for casting mould boards or pattern plates for foundries.
