Description
This unit describes the skills and knowledge required to operate, control and optimise centrifugal casting equipment to produce polyurethane products. This unit applies to an experienced technician working alone or as part of a team.The unit principally refers this a specialised moulding process that uses thermoset polyurethane casting technology, typically for non-rigid lining or machine roller coverings.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. Prepare to centrifugally cast polyurethane materials
  • 1.1 Identify materials, including additives and curatives, from job specifications
  • 1.2 Identify equipment, including handling, control and material preparation equipment, from job specifications
  • 1.3 Perform pre-operational checks including checking for and controlling materials and process hazards
  • 1.4 Identify and check availability of safety equipment according to workplace procedures
  • 1.5 Identify checks and testing processes required for equipment, materials, quality and production management
  • 1.6 Identify waste management strategies to collect excess, discarded or nonconforming materials to be disposed of, recycled or reprocessed according to workplace procedures
2. Perform pre-production tasks for centrifugal casting operations
  • 2.1 Confirm product and process parameters from job specifications
  • 2.2 Check environmental controls are valid and in place
  • 2.3 Calculate quantity of material required to produce product of correct shape and physical dimensions from job specifications
  • 2.4 Determine product colour and obtain appropriate agents from job specifications
  • 2.5 Set production process according to equipment and workplace specifications, and adjust process to optimise output based on selected materials
  • 2.6 Obtain appropriate mould coating and releasing agents
3. Set up and check centrifugal casting equipment
  • 3.1 Inspect and set up centrifugal casting equipment according to workplace procedures
  • 3.2 Ensure that mould is secured or adequately restrained to prevent separation of mould and rotational equipment
  • 3.3 Perform test run of horizontal cylindrical moulds to ensure vibration-free running
  • 3.4 Clean work area and ensure operational sequence and procedures, particularly work health and safety procedures, codes and practices are in place
  • 3.5 Identify and check emergency stops, guards and controls
  • 3.6 Perform test run of rotational equipment to ensure equipment output meets job specifications
  • 3.7 Start up and operate centrifugal casting equipment, and make adjustments to settings to meet job specifications
4. Centrifugally cast polyurethane products
  • 4.1 Ensure process is operating according to equipment specifications including operating temperature, time and rotational speed
  • 4.2 Pour materials at appropriate rate per minute, angle and quantity using necessary aids and assistance to ensure pour is completed within required times and distribution requirements and using techniques to prevent air entrapment and aeration
  • 4.3 Follow checking and testing processes to assess if output, including thickness, weight and product integrity, meets job specifications and quality standards, and apply strategies for managing nonconforming outputs
  • 4.4 Demould, check and store products according to workplace procedures
  • 4.5 Apply waste management strategies according to workplace procedures
  • 4.6 Clean, adjust and lubricate equipment according to equipment specifications and workplace procedures
  • 4.7 Pause or stop equipment in normal and abnormal circumstances according to workplace procedures
5. Anticipate and solve process control problems
  • 5.1 Recognise existing or potential process control variances and their causes
  • 5.2 Determine, prioritise and implement remedial and preventative actions based on identified issues and controls
  • 5.3 Monitor process control variances and corrective actions taken until resolved
  • 5.4 Accurately maintain records and logbooks
