Produce three-dimensional plugs/moulds

Assessment tool

Version 1.0
Issue Date: May 2024


Work may be undertaken autonomously or as part of a team. Predetermined standards of quality and safety are observed and work is carried out following standard operating procedures relevant to industry standards.

Tasks may include the use of hand and mechanical lay-up practices for plug/mould construction.

Hand tools/ power tools and workshop machinery/equipment can also be used in conjunction with construction practices.

This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C5 (AQF level V).

Band: A

Unit Weight: 12

This unit covers manufacturing three dimensional plugs and, where applicable, solid and/or split moulds constructions used in marine vessel construction.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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

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.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
