Question

Rubber forming is a type of forming process in which polyurethane is used as a die material.

(a) True

(b) False

I have been asked this question in an interview for internship.

This interesting question is from Stretch Forming in section Miscellaneous Forming Processes of Casting-Forming-Welding II

Answer 1

Correct choice is (a) True

Best explanation: Rubber forming is a type of forming process in which a polyurethane or rubber pad is commonly used as the die material instead of a rigid material. These materials are highly resistance to the abrasion and have a better fatigue life. And pressures of the order of 100 bar are typical of this process. This process is also called as Guerin process.
