Question

Castings that cannot be made floor molding can be made using ___________

(a) Pit Molding

(b) Injection Molding

(c) Machine Molding

(d) Bench Molding

I had been asked this question in an interview.

My enquiry is from Methods of Sand Moulding topic in chapter Sand Moulding of Foundry and Forging

Answer 1

Correct answer is (a) Pit Molding

The explanation is: Very big castings which cannot be made in flasks are molded in pits dug on the floor. Very large castings can be handled and cast easily through pit molding. In floor molding, the making of such flasks is difficult and not economical.
