Plastics
Vacuum forming used to make trays, casing etc. A mould is pushed into a heated
sheet of soft thermoplastic, getting rid of any air using a vacuum below the mould which
helps to suck out any bubbles, leaving the plastic in the shape of the mould. This process is
often used in batch or mass production. USED LIEKLY TO BE USED IN CD
