The injection moulding process is based on injecting material into a mould. The technique is most commonly performed with thermoplastic and thermosetting polymers. During the injection moulding process an amount of heated liquid mass is injected under high pressure into a mould. The mass cools off and solidifies in the shape of the mould. Injection moulding is used for all kinds of containers, such as butter tubs and yoghurt pots.
