Description This competency covers the joining of a solid polymer to another solid surface using adhesives, cohesives, solvents or other joining materials. The polymer may be thermoplastic or cured or uncured thermoset.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application Application of this unitThis competency applies to operators who are required to join polymers to another surface. It is typically performed by operators working either independently or as part of a work team. The operator will:check the surface of products to be joined for suitability or contaminationcheck materials for conformity to job requirements apply the joining material(s)notice any problems and take required actions deal with non-conforming products, waste and scrapcomplete logs and reports.They may record key variables such as work conditions and production rate and reasons for interruptions.This unit does not include:significant surface preparation - see PMBPROD248C Prepare surfaces for coatingheat curing of bonded material - see PMBPROD265 Operate portable vulcanisingequipment, PMBPROD375B Vulcanise products using an autoclave.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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.

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:

apply the required skills and knowledge to complete adhesive bonding jobs

apply approved procedures.

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

joining production standards are met consistently

all safety procedures are followed.

Assessment method and context

Assessment will occur using industrial bonding situations and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

by using appropriate joining materials, situations and tools

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. 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.


Submission Requirements

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 out of specification products, process problems and materials faults.

Knowledge of organisation procedures, quality requirements and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.

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

Knowledge and skills in the operation of the joining process and equipment sufficient for consistent production of quality products, including:

correct selection and use of equipment or tool/s, materials, processes and procedures

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

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.

Basic numeracy is required, eg to determine the amounts of materials needing to be blended for a 2 pot adhesive.

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.
