Application

This unit describes the skills and knowledge required to operate, adjust and optimise gravity 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 to the wide range of thermoset urethane chemistry and gravity-cast moulding that makes a wide variety of both rigid and flexible 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.

What You'll Learn

1.

  • 1.1 Identify materials, including additives and curatives, 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
  • 1.5 Identify checks and testing processes required for equipment, materials, quality and production management
  • 1.6 Identify housekeeping needs and waste management strategies to collect excess, discarded or nonconforming materials to be disposed of, recycled or reprocessed according to workplace procedures

2.

  • 2.1 Confirm product and process parameters against job specifications
  • 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 required 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 required from job specifications

3.

  • 3.1 Inspect and set up gravity casting equipment according to equipment specifications
  • 3.3 Ensure that mould is secured or adequately restrained to prevent separation of mould and rotational equipment
  • 3.4 Perform test run of production process to ensure output meets job specifications
  • 3.5 Clean work area and ensure, operational sequence and procedures, particularly work health and safety procedures, codes and practices are in place according to workplace procedures
  • 3.6 Identify and check emergency stops, guards and controls

4.

  • 4.1 Ensure process is operating according to equipment specifications including operating temperature, time and rotational speed
  • 4.3 Follow checking and testing process to assess if output, including thickness, weight and product integrity, meets job specifications and quality standards, and apply strategies to manage 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

5.

  • 5.1 Recognise existing or potential process control variances and their causes
  • 5.3 Monitor process control variances and corrective actions taken until resolved
  • 5.4 Accurately complete records and logbooks

Assessment Requirements

Performance Evidence

There must be evidence the candidate has completed the tasks outlined in the elements and performance criteria of this unit, and demonstrated the ability to:
• produce polyurethane products using gravity casting at least once to meet job specifications.

Knowledge Evidence

There must be evidence the candidate has knowledge of:
• function and operating principles of gravity casting equipment, machine components and ancillary equipment
• importance of machine set-up and warm-up for effective processing of materials
• gravity casting manufacturing process and materials demand
• characteristics of materials and their behaviour in relation to process conditions and stages of production
• the criteria for overall process/equipment readiness for the process or equipment being used
• typical quality standards required at each stage of production
• key variables that may affect product quality and production output:
• operating temperatures
• speed of cure
• colour
• location of pouring basin
• cycle time
• use of separating agents
• product weight
• product integrity and general conformance to specification
• typical and atypical process and product problems, including early warning signs, possible causes and corrective actions
• the distinguishing characteristics of causes of problems as being either based on the properties of materials or caused by process variables
• organisational procedures relevant to the work environment or job role
• hazards that may arise in the job or work environment, and:
• their possible causes
• potential consequences
• appropriate risk controls.

Assessment Conditions

Skills must have been demonstrated in the workplace or in a simulated environment that reflects workplace conditions and contingencies.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors
