  • 1.6 Identify hazards associated with the job and take appropriate action.
  • 1.7 Perform other pre-operational checks in accordance with procedures.
2. Start up blow moulding equipment to procedures.
  • 2.1 Conduct pre-start checks.
  • 2.2 Start up equipment safely and 'dry run' to warm hydraulics and components to operating temperature before production, as required.
  • 2.3 Check condition of equipment and introduce raw materials as required.
3. Operate blow moulding equipment to procedures.
  • 3.1 Check process is operating within required limits.
  • 3.2 Check product is in specification and to required quality standard.
  • 3.3 Ensure product is consistently ready for next operation.
  • 3.4 Maintain supply of material(s) as required.
  • 3.5 Complete logs and records as required.
  • 3.6 Collect and segregate scrap, trim and other materials as required.
  • 3.7 Keep equipment and work area clean .
  • 3.8 Pause machine cycle and perform emergency stop, as required.
4. Respond to routine problems to procedures.
  • 4.1 Identify likely faults that occur during the operation.
  • 4.2 Identify and take action on causes of routine faults in accordance with procedures.
  • 4.3 Make sure appropriate records and log books of equipment operations are maintained to meet procedures.
  • 4.4 Identify non-routine problems and report to designated person.
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. 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 blow moulding operations within the plastics and rubber sectors. It includes the operation of all relevant additional equipment where that equipment is integral to the blow moulding process.
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.
Tools and equipment
This competency includes use of equipment and tools such as:
bottom blow, top blow, needle blow, tail to tail blow, parison
pre-blow and pre-squeeze, parison stretching and parison orientation type machines
ancillary equipment (such as chillers/cooling towers, die heating equipment, hopper driers, mixing hoppers, dehumidifying driers, air compressors, dosing machines, colour blending equipment and conveyors)
hand tools used in the blow moulding process
material loading equipment used for loading of raw materials
relevant personal protective equipment.
Hazards
Typical hazards include:
spills
dusts/vapours
slip and fall (such as due to spilt granules)
temperature (such as due to heated moulds)
hazardous substances (including decomposing polymer during start up and shut down)
moving equipment (such as moving moulds, robots and ancillary equipment)
manual handling hazards.
Problems
'Respond to routine problems' means 'apply known solutions to a limited range of predictable problems'. Typical process and product problems may include:
equipment malfunction
variations in temperature, pressure, speed, inflation
variations in materials or contamination of materials
incorrect quantity of materials/additives
die damage
routine blow moulding faults (eg wall thinning, holes, poor surface finish, warping, poor colour dispersion, ejection damage, colour contamination, black spots and other defects)
machine malfunction
die/tooling problems.
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 operate a blow moulding machine
apply approved procedures.
Consistent performance should be demonstrated. For example, look to see that blow moulding production standards are met consistently.
Assessment method and context
Assessment will occur on an industrial blow moulding machine(s) equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
by using an appropriate, industrial blow moulding machine requiring demonstration of operation and emergency stop procedures
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.
