Plastic Die Engineering

Designing and creating plastic moulds from designer drawings for mass produced products of high quality but at low cost.

Why is this skill important?

Plastic die engineering professionals are engaged in the mass production of plastic products by producing a part mould based on drawings by a parts designer.

The designing and processing of the mould is done with the help of software systems; most of the machining is done on CNC (Computer Numerical Control) machines. The machined parts are then polished and assembled to get them ready for trial. Completed moulds will be installed in an injection moulding machine, from which the plastic products will then be manufactured.

These days, there are many different industries that utilize plastic die engineering. Plastic injection moulded components are used in telecommunications, medical, aerospace and automobile industries, for home appliances, office automation, entertainment, and electronics. The different application requirements for each provide challenges to the engineer, ranging from modelling the product and designing the die to manufacturing it, inspection and troubleshooting of any defects prior to mass production.

The skilled practitioner needs excellent levels of skill in numeracy, hand and machining skill, polishing, assembling, testing, and troubleshooting.
