Application

This unit covers the skills and knowledge required to remove and change dies, pins, sizing dies (calibrator/s), vacuum blocks and seals used in extrusion line processes.
This unit applies to an experienced technician working alone or as part of a team.
The unit principally refers to extrusion technology equivalent to die-setting in injection moulding technology and making the required changes to enable a shift to make a new product or use a different polymer.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.

What You'll Learn

1.

  • 1.1 Plan process for shutting down machinery and inform relevant personnel
  • 1.3 Select dies or cores to match product or process specification
  • 1.4 Implement measures to control identified hazards

2.

  • 2.1 Shut down downstream equipment according to equipment specifications and shutdown process plan
  • 2.3 Activate isolating locks and disconnect power to heaters according to equipment specifications

3.

  • 3.1 Remove, clean and store die to prepare for replacement
  • 3.3 Remove and refit calibrator sleeve and seals to meet requirements
  • 3.4 Set heats according to pre-startup procedures

4.

  • 4.1 Check operation of die against product quality and expected operational standard
  • 4.3 Check a first-off sample for compliance with required standards
  • 4.4 Fine-tune settings and other production variables to achieve required output quality
  • 4.5 Compare standard operating procedures with actual production run and note variances
  • 4.6 Accurately complete documentation

5.

  • 5.1 Recognise existing or potential process control variances and their causes
  • 5.3 Monitor process control variances and corrective actions taken until resolved

Assessment Requirements

Performance Evidence

There must be evidence the candidate has completed the tasks outlined in the elements and performance criteria of this unit, and demonstrated the ability to:
• change extrusion die and calibrator at least once to meet requirements, including selecting dies, calibration sleeves, seals and tools.

Knowledge Evidence

There must be evidence the candidate has knowledge of:
• function and principles of the operation of extrusion equipment
• methods of connecting extrusion dies to machines
• extruder and ancillary equipment shutdown processes
• the function of each machine setting and the appropriate ranges of settings for specific dies
• key variables that may affect product quality or production output and appropriate remedies
• typical and atypical process and product problems, including early warning signs, possible causes and corrective actions
• organisational procedures relevant to the work environment or job role
• hazards that may arise in the job or work environment, and:
• their possible causes
• potential consequences
• appropriate risk controls.

Assessment Conditions

Skills must have been demonstrated in the workplace or in a simulated environment that reflects workplace conditions and contingencies
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
