Abstract:
This study is aimed to find out the mechanical and acoustic characteristics of casting traditional bell's result using metal mold and sand mold. The mechanical and acoustic characteristics of casting traditional bell's result are compared between metal molded and sand molded casting.
The bronze alloy was smelted in a crucible furnace at the casting temperatures of 1000, 1050, and 1100 °C. The melted alloy is poured into a sand mold and a preheated metal mold at a temperature of 200 °C. Specimens were formed into bell and billet. The bell form was for acoustic testing. The Billet casted was cut into a few parts and were manufactured as a specimen for hardness test.
This study has showed that mechanical characteristic specifically the hardness of metal molded casting is better than sand molded casting. The Acoustic properties of particular damping characteristicsis depended on the porosity of casting’s result. The bell’s tone isn’t produced by the mono frequency but it’s generated by more than one frequency domain. Similarly, the subjective test of acoustic characteristic didn’t show a significant obvious difference.
