Assessment tool

Version 1.0
Issue Date: March 2024


Application of this unit

This competency applies to advanced operators who are required to apply knowledge of materials, product purpose and processes to the hand operation of chopper guns/depositors for the production of composites. It also requires using a range of well developed skills requiring some discretion and judgement to recognise and resolve a range of problems.

The operator will:

check settings and adjustments of equipment

monitor equipment operation

make appropriate adjustments to correct materials, equipment or process variations

solve composites production equipment and process problems, seeking guidance where necessary or appropriate

complete logs and reports.

This competency covers preparation and hand operation of a resin-glass depositor (chopper gun) to form a composite materials product and the solving of non-routine problems.

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

Prerequisites

Prerequisites

This unit of competency has a prerequisite of PMBPROD280A Operate resin-glass depositor equipment.


Employability Skills

The required outcomes described in this unit contain applicable Employability Skills. The Employability Skills Summary of the qualification(s) in which this unit is packaged will assist in identifying Employability Skill requirements.




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, 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 PMBPROD2980A Operate resin-glass depositor 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 material properties and process variable in relation to the process requirements of the end product.

make adjustments to the process as required.

identify and take appropriate action on problems and potential problems.

Consistent performance should be demonstrated. For example, look to see that:

composites production standards are met consistently

all safety procedures are always followed.

Assessment method and context

Assessment will occur on chopper-gun depositor equipment and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

using an appropriate processing plant

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.

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.

This describes the essential skills and knowledge and their level required for this unit.

Application of knowledge of the materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production.

Knowledge of organization procedures, quality requirements at each stage of production and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.

Application of the knowledge of managing risks using the hierarchy of controls applied to the composites process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.

Show knowledge as a basis for solving processing and material problems including:

operation of resin-glass depositor, equipment and components

production workflow sequences and materials demand

properties of the materials required to form a composite structure of the required strength and surface finish, including the importance of gel coat properties and bonding

requirements for correct spraying of materials to the mould surface

pot life of the resins used

cleanout procedures

impact effects of variations in raw materials and equipment operation in relation to quality of final product

correct selection and use of equipment, materials, processes and procedures

polymer properties and their interactions with process conditions

relationships between polymer properties and process conditions

changes to polymer properties to better suit process requirements.

product problems related to polymer properties

product problems related to process conditions

adjustments to process conditions to meet polymer and product requirements.

Competence also includes the ability to:

plan own work, including predicting consequences and identifying improvements

identify and describe own role and role of others involved directly in the process

maintain output and product quality using appropriate instruments, controls, test information and readings

identify factors which may affect product quality or production output and appropriate remedies

identify when the when assistance is required to solve problems.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications, job sheets, procedures, material labels and safety information as provided to operators.

Writing is required to the level of completing workplace forms.

Numeracy is required to the level of determining required weights/volumes of materials in a resin mix for different circumstances (say using a data sheet), number of layers of impregnated matrix required to yield the required product laminate thickness, and similar activities.

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.
