Description
This unit of competency defines the skills and knowledge required for die correctors working in an aluminium extrusion workplace who are required to undertake the initial testing of new extrusion solid and hollow dies. It includes liaison with die designers and makers on the performance of the new die and making corrections to the die to ensure optimal performance.No licensing, legislative or certification requirements apply to this unit at the time of publication.Band: AUnit Weight: 4
Notes
Elements and Performance Criteria
1 Determine job requirements
  • 1.1 Follow standard operating procedures (SOPs)
  • 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 Interpret die drawing and die specifications relevant to die trial
  • 2.1 Identify regulatory requirements and risk management requirements associated with extruder operation and die handling
  • 2.2 Identify layout and pre-forming of die apertures
  • 2.3 Identify bearing and pocket design/specification
  • 2.4 Identify measurements and tolerances for bearings, die components and die support system
  • 2.5 Identify bolster and spacer specification for die
  • 2.6 Identify press specifications
  • 2.7 Identify speed estimate for die
  • 2.8 Identify ports and bridges for hollow dies
3 Liaise with die designer
  • 3.1 Clarify die drawing and die specifications with die designer where design information is not clear
  • 3.2 Determine if die requires finishing off and clarify final design measurements, tolerances and speed specifications
  • 3.3 Obtain any special instructions from die designer for conduct of test extrusions
4 Finish off die, if required
  • 4.1 Finish lands and bearings to specified tolerances
  • 4.2 Finish ports, bridges and mandrels of hollow dies, if required
  • 4.3 Undertake any final polishing
  • 4.4 Confirm all measurements are to design specification after finishing off
5 Analyse trial extrusions
  • 5.1 Check extruder and surrounds for compliance with operation safety requirements
  • 5.2 Operate or supervise operation of extrusion press to produce trial extrusions
  • 5.3 Check hot extrusions for shape distortion
  • 5.4 Check thickness of extrusions are to specification
  • 5.5 Check surface finish of extrusions
  • 5.6 Identify whether faults apply from the start to the end of the run-out of the extrusions
  • 5.7 Conduct additional trial extrusions to confirm extrusion faults occur consistently
  • 5.8 Record extruder settings for each trial extrusion
6 Identify appropriate remedy for out-of-specification results
  • 6.1 Examine faulty extrusions and determine if fault relates to die design, incorrect process or temperature settings, or faulty die support system
  • 6.2 Determine fault is die related and able to be eliminated through correction of die
  • 6.3 Determine if fault can be corrected through adjustments to die supports
  • 6.4 Determine if fault can be eliminated through adjusted process control or billet heating
  • 6.5 Recommend either return of die for re-design or manufacture of a new die where faults are unable to be corrected
7 Re-test die after correction
  • 7.1 Conduct trial extrusions after correction of die, die support adjustment or process or temperature adjustment
  • 7.2 Return die to die manufacturer if faulty extrusions persist
  • 7.3 Record adjustments to die on die design drawings ensuring correct feedback codes are used
  • 7.4 Record adjustments made to die support system, process and temperature settings
