Preparation of synthetic moulding sand using local

Abstract. Efforts have variously been made to develop synthetic moulding sand for foundry mould production from locally sourced ingredients. This research investigates the suitability of usingThe sand used for dry sand moulds contains 1 to 2% cereal flour and 1 to 2% pitch. The prepared moulds are baked in an oven at 110 to 260°C for several hours. The additives increase the hot strength due to the evaporation of water as well as by the oxidation and polymerization of the pitch. Dry sand moulds can be used for large castings.Addition of coal dust to the green moulding sand is to improve

Transformation of bentonite used in green sand molds during

The assessment of the binding properties of bentonites used for molding sand and its deformation at varying temperature is well studied in the literature. The technological properties of molding sand such as compactibility, permeability, compression strength have been examined (Holtzer et al., 2011; Zymankowska-Kumon et al., 2012; If it is possible to do this safely, take a sample from the belt taking sand to the moulding station. Approximately 2kg to 3kg of sand is needed, and should be kept in an air-tight container; a polythene bag is ideal. 2.2 Sand Testing. 2.3 Preparation of Standard Test Pieces. 2.4 Determination of Moisture Content.Moulding and Sand South African Institute of Foundrymen
