A trimming press is a machine tool which is widely used for removing the excess material from the casting part.

(a) True

(b) False

I had been asked this question in an online interview.

This is a very interesting question from Steps Involved In Making a Mold in division Mold and Mold Making of Casting-Forming-Welding I

Answer 1

Right option is (a) True

To explain I would say: During solidification, the material from the channels in the mould solidifies and joined to the casting part. This excess material should be trimmed from the casting part, for which a trimming press is used that removes excess material very finely. The time needed for trimming the excess material can be estimated from the size of the casting’s envelope.
