Unit of competency
Modification History
Release 2. Quantum of hours of workplace practice removed. Supersedes and is equivalent to MEM04022 Examine appropriateness of methoding for mould design (Release 1).
Release 1. Supersedes and is equivalent to MEM04022A Examine appropriateness of methoding for mould design.
Application
This unit of competency defines the skills and knowledge required to examine the methoding (gating, running and feeding of castings) for mould designs using basic metallurgical techniques and skills. This work is under the overall direction of a metallurgist.
It applies to a foundry tradesperson who has to examine the appropriateness of own or others methoding for a mould design using basic metallurgical skills and techniques supported by normal empirical trade skills.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
