Change extrusion die and setup
|Unit Descriptor||This competency covers the removal and refitting of dies, pins, sizing dies (calibrator), vacuum blocks and seals in preparation for production. This competency applies to extrusion, and similar, dies. For all other dies use PMBPREP304A Change equipment dies. This competency is typically performed by advanced operators demonstrating some relevant theoretical knowledge and using a range of well-developed skills requiring some discretion and judgement.|
|1 . Prepare to change dies or cores.||

|4 . Restart and test-run the new setup.||
|5 . Anticipate and solve problems||

This competency unit includes the selection and fitting of dies and cores.
This competency applies to all work environments and sectors within the plastics, rubber and cablemaking industry which use extrusion type dies and cores. It includes the operation of all relevant ancillary equipment.
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
Tools and equipment
This competency includes use of equipment and tools such as:
hand carts and trolleys
hoists/lifting equipment not requiring any special permits or licences basic hand tools
relevant personal protective equipment.
Typical hazards include:
manual handling hazards
Typical process and product problems may include:
lack of cleaning leading to corrosion
fine adjustments to optimise production.
Key variables to be monitored include:
fitting and adjustments to die
adjustments to extruder settings
quality of the product against product specifications.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the ability to perform a die-change smoothly and methodically, which will put the extruder back into full production of in-specification product in standard time. In particular it is essential that the operator can:
select, install and check the performance of die and cores
locate, interpret and apply relevant information
maintain workplace records
identify and safely handle products and materials
apply safety precautions appropriate to the task
recognise potential situations requiring action and then implement appropriate action.
Consistent performance should be demonstrated. For example, look to see that production standards are met consistently.
Assessment method and context
It is preferred that assessment takes place on an industrial extruder in a work environment.
Competence in this unit may be assessed:
on a processing plant, allowing for operation under all normal and a range of abnormal conditions
in a situation allowing for the generation of evidence of the ability to respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom
