Development Of Low Cost Block Mold For Copper Alloy Casting

Suitable block mold formulations for copper alloy casting have been developed and the formulations used were 25% plaster of paris (POP), 75% silica sand and 31-37% water. Silica sand with a grain size of 106-212 µm was added into dilute suspension of POP and the mixing process was continued until a...
