MEM07042 — Undertake corrections and basic maintenance to aluminium extrusion dies and die support systems

1 Determine job requirements

• 1.1Follow standard operating procedures (SOPs)
• 1.2Comply with work health and safety (WHS) requirements at all times
• 1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
• 1.4Identify job requirements from specifications, drawings, job sheets or work instructions

2 Prepare for die correction

• 2.1Identify regulatory requirements and risk management procedures relevant to die access and handling, extruder operation and die correcting procedures
• 2.2Identify extrusion specifications, extruder operating procedures and other information relevant to die correction task
• 2.3Consult with die designer on intended correction, where required
• 2.4Select appropriate hand tools, hand held power tools, or workshop machines to carry out die corrections

3 Correct solid dies

• 3.1Calculate intended change in extrusion flow or speed
• 3.2Determine bearing choke angles or length of bearing shortening as appropriate for required correction
• 3.3Speed up flow through appropriate shortening of bearing
• 3.4Slow down flow through appropriate choking of bearing
• 3.5Relieve clearances
• 3.6Supervise or run trial extrusions to test corrections

4 Correct hollow dies

• 4.1Assess if shortening or choking of mandrel bearings is required and select bearings to be corrected
• 4.2Determine choke angles and length of shortening as appropriate for required corrections
• 4.3Undercut mandrel to widen chambers
• 4.4Increase depth of chamber back into bridge
• 4.5Adjust mandrel stems
• 4.6Adjust weld bridges
• 4.7Speed up flow through appropriate shortening of bearing
• 4.8Slow down flow through appropriate choking of bearing

5 Undertake basic maintenance of dies

• 5.1Monitor case and assess when re-nitriding is required
• 5.2Prepare die for re-nitriding
• 5.3Clean and polish dies
• 5.4Repair fine bearing damage
• 5.5Maintain bearing angle and flatness during polishing and repairs
• 5.6Monitor fittings and devices for lifting die and die support components and arrange replacement or repair as necessary

6 Adjust die support system and components

• 6.1Ensure toolstack components are flat and square with die and specified toolstack dimensions that will support dies, according to the force the extruder can exert are used
• 6.2Check for and replace any coined bolsters
• 6.3Check die slide alignment is within tolerance and re-align if necessary
• 6.4Report persistent die support related faults after adjustment and recommend redesign or stiffening as appropriate

7 Maintain die records

• 7.1Record details of all die corrections, including trial extrusions
• 7.2Recommend any simple die design changes that increase productivity and recovery

What does an assessment tool for MEM07042 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM07042 needs to address all 107 unit components: 7 elements with 34 performance criteria, 8 performance evidence requirements, 65 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for MEM07042?

Auditori pulls the current release of MEM07042 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEM07042 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM07042 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEM07042, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
