Question

The metal pattern is more useful over wood patterns.

(a) True

(b) False

I had been asked this question in an online interview.

My question is based upon Pattern Materials in division Pattern Materials & Moulding Sand Tests of Foundry and Forging

Answer 1

Correct option is (a) True

For explanation I would say: Molding sand is made up of highly abrasive particles for the large scale production and metal pattern provide higher resistance to abrasion over the wood patterns. Hence, where ever possible, metal patterns are preferred over the wood patterns.
