METHOD OF PRODUCING SPECIMEN PRECISION CASTING MOULDS FOR HYDRODYNAMIC STUDY PURPOSES

摘要

A standard mould used in precision foundry work for hydrodynamic studies of the filling conditions of manufacturing moulds is manufactured by the following method: - positioning a wax master form of the parts in a box made from transparent material; - coating by deposition of layers of a transparent material of the silicon-resin type followed by degassing and polymerisation; - dissolution of the master form.
