Abstract

Due to the fact that ceramic shell mould structure is highly sensitive to any thermo physical changes therefore the drying procedure in the shell mould build up process is very important in producing good and quality of the end cast products. The aim of the study is to investigate the most appropriate drying technique for ceramic shell mould making process. In this study, the ceramic shell mould was dried using three techniques; microwave, oven and natural. Two parameters (shrinkage and microstructure) that strongly related to the shell mould performance were selected to measure the property and characteristic of the dried shell mould. Based on the comparison of these three drying methods, it shows that microwave drying technique gives the lowest shrinkage value and the finer and homogenous microstructure.
