Advantages:
-> Repeatable - the same design can be achieved every time with very good accuracy.
-> Economic - hundreds of copies of the design can be produced before the machinery needs to be maintained.
-> Intricate - intricate designs can be achieved very easily.
-> Quick - designs can be produced very quickly
-> Accurate - designs are produced to a high level of accuracy each time.
-> Little waste - there is very little flash and hence very little waste plastic.
Disadvantages:
-> Costly: the capital costs of machinery, development and maintenance are high.
-> Restricted: designs are restricted by what can be achieved with the die.
-> Materials: restricted to thermoplastic materials.
