5.4. Where applicable, mould is prepared for production run/s.

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Look for evidence that confirms skills in:

  • identifying materials, such as timber, plywood, fastenings, fillers etc. from specifications/drawings
  • selecting and using hand tools, hand held power tools and workshop machinery to suit plug/mould construction
  • marking out dimensions relevant to plug/mould components
  • selecting and assembling materials
  • constructing plugs and moulds
  • modifying plugs/moulds through the addition of release angles/tapers, flanges, beads and rounding/concaving
  • fitting reinforcement components and or materials
  • checking external/internal dimensions against specification/drawings
  • applying final finish coating/s
  • sanding, buffing/polishing to preparing plug for mould lay-up
  • removing and disposing of waste

Required knowledge 

Look for evidence that confirms knowledge of:

  • plug/mould construction materials, characteristics, applications
  • plug/mould coating materials, characteristics, applications - including tooling coats
  • correct dimensions and application procedures for marking out
  • release angles/tapers, flanges, rounding/concaving of corner sections
  • hand tools/hand held power tools and workshop machinery and their uses
  • plug/mould construction methods
  • if applicable, methods used to apply stiffening/bracing/reinforcement
  • method of application and sequence of final finish coating
  • procedures for sanding/buffing/polishing plug/mould
  • fault identification and rectification
  • waste removal and disposal procedures

Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to produce three-dimensional plugs/moulds. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment 

This unit may be assessed on the job, off the job or a combination of both. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with producing three-dimensional plugs/moulds, or other units requiring the skills and knowledge covered by this unit.

Method of assessment 

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment 

Range Statement

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. Bold italicised wording, if used in the performance criteria, is detailed below. 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) may also be included.

Materials 

Timber, metal, plastic, fibreglass composites, fillers etc.
