Question

In the sand slinging process we can’t use a pattern with extension or projection.

(a) True

(b) False

This question was addressed to me in quiz.

My question comes from Methods of Ramming Mold Boxes topic in portion Mold and Mold Making of Casting-Forming-Welding I

Answer 1

The correct option is (a) True

Best explanation: During sand slinging, sand is thrown with a higher amount of force into the mold box and will hit the projection present on the pattern. This will result in the damage of the pattern. Thus, the sand slinging operation is used only for a simple pattern without any projection or extension.
