Unit of Competency | PMBTECH301B - Use material and process knowledge to solve problems |
---|---|---|---|
Description | This competency covers the application of a knowledge of polymers, their additives and their interactions with the process to the solving of problems. It may be applied in any sector of the industry. This unit covers polymer properties and their application in general to processes. The application in specific processes is covered in the specific process units.This competency is typically performed by advanced operators working either independently or as part of a work team. | ||
Employability Skills | This unit contains employability skills. | ||
Learning Outcomes and Application | Application of this unitThis competency applies to advanced operators who recognise potential process problems and analyse process problems using their knowledge and understanding of the polymer materials they are processing. The problems are broader and/or require more knowledge of the properties of polymers than those which apply to a single work station and which may be an element of a 'PROD' competency.It includes:a basic knowledge of different polymer materialsa basic knowledge of the applications of different polymersa basic knowledge of the different properties of polymersan understanding of the relationship between process conditions and polymer properties. | ||
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.
Where the assessee does not currently possess evidence of competency in PMBPROD235B Use materials and process knowledge to complete work operations, 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 apply a theoretical understanding of polymers to workplace problems.
Assessment method and context
Assessment will occur using industrial polymers and work-like scenarios.
Competence in this unit may be assessed:
using appropriate, industrial scenarios and problems
in a situation allowing for the generation of evidence of the ability to recognise, anticipate and solve 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.
Knowledge of polymers and how their properties vary and the relevance to these properties to processing and product. Descriptions of polymer molecular shape and arrangement should be limited to commonly accepted diagrammatic representations of these structures. Knowledge of organization procedures and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.
Knowledge as a basis for solving processing and material problems including:
type of polymer and polymer structure
impact of additives
the importance of flow and flow properties
the impact of temperature and heating/cooling rate on processing and properties
Competence also includes the ability to distinguish between the causes of faults such as:
wrong raw materials/additives or wrong grade
incorrect quantity of materials/additives
contaminated materials/additives
out of specification materials
process set-up and/or operation.
Language, literacy and numeracy requirements
This unit requires the ability to read and interpret technical specifications and similar information.
Writing may be required to the level of completing workplace forms.
Numeracy is required to the level of understanding the significance of numbers and being able to interpret numerical data.
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 all work environments and sectors within the plastics, rubber and cablemaking industry. It includes the operation of all relevant equipment.
Standard procedures means all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
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.
Polymer properties
Polymer properties related to flow include:
molecular weight
molecular structure
factors effecting viscosity.
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.
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.
