Abstract

PURPOSE: To prolong a mold leavable time and obtain the cast products of superior casting surfaces by forming a film of synthetic resin or inorganics using these as a binder on the molding surface of a mold.
CONSTITUTION: A film of a synthetic resin such as vinyl chloride, vinyl acetate or polyester or an inorganic material using these as a binder is formed on the molding surface of a mold by means such as brushing or spraying. The thickness of the film is preferably about ≤1mm. The mold leavable time is prolonged by the heat insulating action of this film, and the casting surfaces are made beautiful.
