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.

1.2

Comply with work health and safety (WHS) requirements at all times

1.3

Use appropriate personal protective equipment (PPE) in accordance with SOPs

1.4

Identify job requirements from specifications, drawings, job sheets or work instructions

2

Evaluate proposed mould design for methoding requirements

2.1

Identify risk management strategies to minimise defect formation

2.2

Identify desired solidification process and take into account casting design, metal composition, mould design and specifications

2.3

Identify running, gating and feeding principles and techniques appropriate for the particular casting

2.4

Identify methods to minimise shrinkage, porosity, segregation, hot tearing and shear

2.5

Examine suitability of methoding, including gating and the number, placement and sizing of feeders/risers

2.6

Enter data where required to facilitate the generation of a computer simulation of methoding and casting process for later comparison to actual casting

3

Report results

3.1

Compare casting results with computer simulated predictions

3.2

Determine reporting requirements

3.3

Prepare reports and circulate for feedback and file in accordance with SOPs

3.4

Communicate suggestions for improvements directly to other team members where appropriate
