Application
This unit describes the skills and knowledge required to remove, refit and set approved and operational dies used in injection moulding.
This unit applies to an experienced technician working alone or as part of a team.
The unit principally refers to an in-production changeover of the die or mould to make a new product, using dies or moulds that have been trialled and have approved set-up specifications.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
