Question

Inorganic type of core binders is generally preferred as compared to organic core binders in core making procedure.

(a) True

(b) False

The question was asked by my college professor while I was bunking the class.

Origin of the question is Core Making Machines topic in section Foundry Mechanizations of Casting-Forming-Welding I

Answer 1

Correct option is (b) False

The explanation is: In general, the binders are present as inorganic as well as organic ones, but for the core making process, organic binders are normally preferred because they are combustible and can be easily destroyed by the heat at high temperatures thereby providing the sufficient collapsibility to the core sand.
