Question

For proper venting, the pouring time is increased which allow easy escape out of gases from the mould without inducing any defects.

(a) True

(b) False

This question was posed to me during a job interview.

Question is taken from Venting of Moulds in portion Mold and Mold Making of Casting-Forming-Welding I

Answer 1

Right option is (b) False

Explanation: For maintaining the proper venting, the pouring time cannot be increased because that will cause other problems in the casting process such as early solidification which will form the incomplete sections in the casting and several defects in the casting components like cracks and shrinkages.
