EXPERIMENTAL STUDY AND ANALYSIS OF COMPRESSIVE STRENGTH IN NOBAKE SAND
Abstract: No bake molds are expendable sand molds, similar to typical sand moulds, except they also contain a quick-setting liquid resin and catalyst. In no bake molding process the moulding sand is poured into the flask and held until the resin solidifies, which occurs at room temperature. It is called as a cold-setting process, as there is no heat involved in it. As a result of this molding process, mold produced …
