Question

It is possible to provide any kind of internal features to the casting by the help of pattern.

(a) True

(b) False

I have been asked this question in a national level competition.

Question is from Steps Involved In Making a Mold in section Mold and Mold Making of Casting-Forming-Welding I

Answer 1

Right answer is (b) False

To explain I would say: It is not always possible to use pattern for generating internal features to the casting. Any kind of internal features of the casting which cannot be produced by the application of pattern are produced by using the separate cores which are mostly formed by the sand that can be green sand or dry sand, depending on the purpose.
