Question

Which of the following processes is the first step involved in the sand casting?

(a) Clamping

(b) Cooling

(c) Mould making

(d) Pouring

The question was posed to me during an interview.

My doubt stems from Steps Involved In Making a Mold topic in chapter Mold and Mold Making of Casting-Forming-Welding I

Answer 1

The correct option is (c) Mould making

Best explanation: The first step involved in the sand casting method is to produce the mould for the casting. In an expendable moulding process, this step should be done for each different casting. A sand mould is basically produced by packing sand mass into each half of the mould. The sand mass is rammed near at the pattern side; pattern is a replica of the casting to be made.
