    Review of Sand Inclusion Defect Analysis to Initiate the Improvement in FNB Casting Process

    By Shailee G. Acharya, Kartik Kothari, Jeetendra A. Vadher

    Abstract: Sand inclusion is an important defect in grey cast iron castings. On an average, this defect accounts for 30 to 40% of the total number of defects arising in the foundries. Sand inclusion is undesirable since it ends up in reducing the strength of the castings and worsens the finish of the casting surface. Hundred or more parameters are responsible for sand inclusion defect and hence it is cumbersome and …

    Improving the Performance of Foundry Industry through FNB Sand Mould System

    By Shailee G. Acharya, Jeetendra A. Vadher, Kartik Kothari

    Abstract: There are many new advanced technologies for casting of metal, furan no bake (FNB) sand casting remains one of the fastest spreading and used casting processes today due to the lower cost of raw materials, a wide variety of castings with respect to composition and size, and the possibility of reclaiming the moulding sand. The FNB sand casting process is one of the most versatile processes in manufacturing as it …

    Ecofriendly Foundry Sand Binders: A Review

    By Shailee G. Acharya, Jeetendra A. Vadher

    Abstract: The casting process is the most versatile manufacturing process. It involves pouring of metal into a mould, thus the mold material and molding method must be selected with care. Resin bonded sand casting is a high demanding technology due to its good surface finish, dimensional stability and shakeout characteristics. This paper reviews the different types of binders used in casting process to produce moulds. The Foundry industry has found itself …

    Improvement in Furan No-bake Molding System to Reduce Defects

    By Shailee G. Acharya, Jeetendra A. Vadher, M. V. Sheladiya, Mahesh Madhnani

    Abstract: Normal 0 false false false EN-US X-NONE X-NONE Casting foundry markets will continue to face challenge from global producers because of their lower wage scales and ecological standards, which lower the cost of their casting jobs. Production constraints on the foundry industry’s processes are increasingly more costly to the industry and cut into the profit. Casting foundries have also made changes to their processes to help decrease pollution. One of …
