Which of the following molding methods is the most costly? Correct Answer Sand slinging

Sand slinging machine is costly, also involves more cycle time and thus results in higher power consumption. Thus the cost involved is more. In jolting and jolt with squeezing machine cost is less with less cycle time, and in hand molding, no machine is used thus less costly than sand slinging.
