Description
This unit describes the skills and knowledge required to safely operate, control and optimise extrusion blow moulding processes to produce products to the required specification.This unit applies to an experienced technician working alone or as part of a team.The unit principally refers to the practical skills for the operation of the polymer extrusion section, which may involve a single- or multi-layer extrusion set-up in the compound production machine. This is standard polymer extrusion technology; however, the electro-hydraulic articulation of the moulds and deflashing units is unique to the production of extrusion blow moulded products.No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
Notes
Elements and Performance Criteria
1. Plan work requirements
  • 1.1 Identify and check materials requirements, including additives and regrind and their amounts or percentages, from job specifications
  • 1.2 Identify equipment and processes required for production and upstream and downstream operations from job specifications
  • 1.3 Perform pre-operational checks including checking for and controlling hazards, checking planned and historical maintenance fixes and confirming that any historical issues have been appropriately addressed
  • 1.4 Identify and check emergency stops, guards and controls
  • 1.5 Identify checks and testing processes required for equipment, materials, quality and production management to meet job requirements
  • 1.6 Identify housekeeping tasks and waste management strategies to collect excess, discarded or nonconforming materials to be disposed of, recycled or reprocessed according to workplace procedures
  • 1.7 Check availability of post-moulding labelling, packaging and storage consumables to complete the task once in operation
2. Perform pre-production tasks
  • 2.1 Verify equipment and mould requirements against job specifications
  • 2.2 Set production process according to equipment and job specifications, and adjust process to optimise output based on selected materials
  • 2.3 Set up and adjust blow moulding equipment for shot size, parison control, die gap, temperature, screw speed, cycle speed, slow close setting (or cushion) and timing to meet job specifications
  • 2.4 Verify raw materials are correct against job specifications
  • 2.5 Set up date, batch and materials markings according to workplace procedures
  • 2.6 Undertake other pre-startup checks according to equipment specifications and safe workplace procedures
3. Operate equipment and make adjustments
  • 3.1 Start up equipment safely and run through a ‘dry cycle' to warm hydraulics and components to operating temperature before production
  • 3.2 Operate blow moulding equipment safely, and adjust settings to meet job specifications
  • 3.3 Ensure process is operating according to equipment specifications and workplace procedures
  • 3.4 Follow checking and testing processes to assess if output meets job specifications and quality standards, and apply strategies for managing non-conforming outputs
  • 3.5 Maintain continuity of process to support production requirements
  • 3.6 Accurately complete logs and records and any observations that require attention
  • 3.7 Apply waste management strategies to collect excess, discarded or nonconforming materials to be disposed of, recycled, or reprocessed according to safe workplace procedures
  • 3.8 Clean work area, and clean, adjust and lubricate equipment, according to equipment specifications and workplace procedures
  • 3.9 Pause or stop machine cycle in normal and abnormal circumstances according to safe workplace procedures
4. Anticipate and solve process control variances
  • 4.1 Recognise existing or potential process control variances and their root causes
  • 4.2 Determine, prioritise and implement remedial and preventative actions based on identified issues and causes
  • 4.3 Monitor process control variances and corrective actions taken until resolved
  • 4.4 Accurately maintain records and logbooks
4. Shut down equipment
  • 4.1 Shut down equipment according to equipment instructions and workplace procedures
  • 4.2 Complete equipment clean-up and post-production adjustments according to equipment instructions and workplace procedures
  • 4.3 Put guards, locks and notices in place to prevent inadvertent start-up
  • 4.4 Accurately complete workplace shutdown documentation, including logging identified safety issues or concerns that require attention and notify management and/or maintenance for action according to workplace procedures
