I have been asked this question in homework.

I'd like to ask this question from Injection Moulding Process topic in chapter Moulding with Polymers of Casting-Forming-Welding II

Answer 1

Correct answer is (c) Injection moulding

The explanation: Injection moulding is a manufacturing process which uses thermoplastic and thermosetting plastic materials to make products like bottle caps, automotive dashboard, combs etc. In this process, material is fed into a barrel of high temperature, then by mixing it is forced into a mould cavity where it solidifies and gets hardened.
