Why it matters
This objective helps connect Forming, redistribution and addition processes to exam-style questions, flashcards, and revision notes for Forming, redistribution and addition processes.
Quick student answer
Which of the following processes is best suited for producing hollow plastic objects?
Direct answer
Blow moulding is the most suitable process for producing hollow plastic objects, such as bottles.
Key terms
- Thermoforming: A process of shaping plastic sheets by heating and forming them over a mould.
- Injection Moulding: A manufacturing process for producing parts by injecting molten material into a mould.
Common trap
Confusing thermoforming with vacuum forming: Remember that thermoforming involves heating plastic sheets, while vacuum forming specifically uses vacuum pressure to shape the material.
