Processes Shaping plastics
There are a number of different plastic shaping processes. With plastic moulding techniques the plastic material is melted and given its shape when cooled in a die.

The majority of plastic parts are made with plastic injection moulding techniques. It is a special type of moulding, where the moulded plastic is pressed automatically into a steel die.

Most composite materials consists partly of plastic material and processes used for shaping those are therefore also described here.
