1.	Additives can be used for the non-ferrous application to avoid the poor collapsibility of the mould.(a) True(b) FalseThe question was posed to me in an interview.This interesting question is from CO2 Process in division Special Casting Techniques of Casting-Forming-Welding I
Answer» Right ANSWER is (b) False To elaborate: In Co2 moulding, POOR COLLAPSIBILITY of the mould is a major disadvantage. Although some additives are used for the improvement in the properties of ferrous METAL castings, these additives which are added to the sand mixture, cannot be applicable for the non-ferrous APPLICATIONS.
