Abstract
A method of manufacturing molds and cores with the help of models and boxes of heated cores, characterized in that a sandy-resinous pulp, containing a synthetic or natural binder and a surfactant, is subjected to swelling in a kneader until the obtaining the state of fluidity, and then cast in the frames or boxes of cores heated to the temperature of 100 to 300º c.
