Past, Present and Future of FNB Mould System

Abstract

This review paper is dealing types of binders used in foundry industries. The different binders have advantages and limitations. This paper gives direction on selection of binder system in different metals. This mainly focuses on selection, advantages and limitations in motor body castings. The data was collected from Krislur Castomech Pvt. Ltd., Chitra G.I.D.C., Bhavnagar. The binder system improves productivity of foundry industries by reducing process cycle time. FNB system also produces the net shape product and with good surface finish. This two part no-bake sand mould system is a mixture of sand with furfuryl alcohol as a resin and sulphonic acids as a catalyst. The resin percentage is on the basis of sand and catalyst on the basis of binder percentage.
