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 will have a better surface finish than any other type of sand molds. No bake sand with high productivity, reduces energy consumption, improves dimensional accuracy, and less curing time escalates its priority of usage in automobile sand casting industries. This paper analyses the change in the compressive strength of No bake sand by varying resin percentage and the loss of ignition (LOI) in each iterations. Four samples (A, B, C, D) are prepared, by various resin percentage. The Graphs are inferred from the results and it was recommended to an automobile sand casting concern.
