Application
This unit of competency defines the skills and knowledge required to manufacture all types of metal patterns, master patterns, core boxes and associated equipment, including cast plates made directly or from a master pattern.
Patterns may be integral with the plate or mounted to the plates with gating and depending upon specifications, production core boxes also may be loose or mounted into core box rigs.
Where the manufacture of polymer production patterns is required unit MEM04011 Produce polymer patterns should also be selected.
Where the selection and use of precision measurement is required unit MEM12003 Perform precision mechanical measurement should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
