(c) Jolting

(d) Hand molding

I would like to ask this question from Methods of Ramming Mold Boxes topic in section Mold and Mold Making of Casting-Forming-Welding I

Answer 1

Right choice is (a) Sand slinging

The explanation: 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.
