Revise: Principles of Plastic Moulding ProcessesCompression moulding is mainly used with thermosetting plastics, although certain thermoplastics can also be compression moulded.
Explain what shapes the plastic: compressed air in blow moulding, air removal in vacuum forming, direct pressing in press moulding, and a hydraulic press in compression moulding.
Keep press moulding and compression moulding distinct: press moulding starts with a heated sheet placed over a mould; compression moulding starts with polymer placed inside a heated mould cavity.
