Taguchi’s based approach to optimize the foundry’s green sand casting process parameters

The worldwide foundry industry’s development prospects have been greatly enhanced by the spike in demand for metal casting across numerous industries. For a foundry to successfully satisfy output requirements, it is essential to achieve optimal performance with low faults. For manufacturing to be effective, problems in the product must be found and fixed via methodical examination. This work illustrates how Taguchi’s design of experiments methodology may be used to optimize the sand casting process’s characteristics.An L9 orthogonal array and the Taguchi optimization technique are used to optimize the sand casting process parameters, and experimental analysis is used to verify the results. Important factors are taken into consideration, including the response variable of weight percentage inaccuracy and characteristics like moisture percentage, mould hardness number, and green compressive strength. Experimental testing validates the results, which show a decrease in weight % error and, in the end, improved casting quality. The weight of the cast product noticeably increases with use of the Taguchi optimized parameters. This emphasizes how critical it is to reduce casting flaws since doing so produces more evenly and densely cast products, which improves overall quality.
