Elements and Performance Criteria

RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.
Context
This competency applies to the production of composite products (typically pipes) by centrifugal casting processes within the plastics and rubber industries. It includes the operation of all relevant additional equipment where that equipment is integral to the composites forming process.
Procedures
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 including:
dies, moulds, mandrels, formers
sprays and fibre lay up equipment
hand tools, eg knives, cutters
equipment for centrifugal casting and curing
relevant personal protective equipment.
Hazards
Typical hazards include:
hazardous vapours
hazardous materials
manual handling hazards
moving machinery hazards
temperature
equipment operations.
Problems
'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.
Typical process and product problems may include:
cracks, dents or imperfections of the mould, mandrel, former, die
adjustment of resin and fibre applicators
variations in materials, colour, consistency or mix
adjustment and settings of the equipment
contamination of materials
curing conditions
variations in materials and/or contamination of materials
processing problems
wrong raw materials/additives/catalyst
incorrect equipment set-up, eg speed, material supply, temperature
curing problems, conditions or equipment
incorrect quantity of materials
contaminated materials.
Variables
Key variables to be monitored include:
operating temperatures
speed
colour
cycle time
output rate
product weight
product integrity and general conformance to specification/sample.

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the assessment guidelines for this training package.
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.
Where the assessee does not currently possess evidence of competency in PMBPROD296A Operate centrifugal casting equipment, it may be co-assessed with this unit.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and centrifugal casting composites process characteristics in relation to the process requirements and the end product
plan own work process within workplace procedures and explain the reasons for the steps in the process
take appropriate action to observe equipment, materials and products for out of specification results, make adjustments and identify problems to be reported.
Consistent performance should be demonstrated. For example, look to see that:
production quality and output standards are met consistently
problems are anticipated from process observations
problems are efficiently resolved
the process runs consistently and smoothly.
Assessment method and context
Assessment will occur on an industrial centrifugal casting machine(s) equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
using an appropriate, industrial centrifugal casting machine
in a situation allowing for the generation of evidence of the ability to recognise, anticipate and 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. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
