Application

This unit of competency defines the skills and knowledge required to prepare flexible moulds for the purpose of replicating an original model.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications, job sheets or work instructions in producing rubber moulds for lost wax casting process

selecting appropriate frame including various shapes and sizes, solid or component systems and preparing master frame

cutting rubber using appropriate measurements, packing into frames and selecting variables of time, temperature and pressure for the appropriate curing system

selecting and using appropriate tools and methods for the release of master without damage.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

SOPs

procedures for assessing frame system

specific master requirements

features and working limitations of rubber, including shrinkage and transparency, and procedures for assessing rubber and master suitability and compatibility

packing techniques for a range of situations

methods for establishing the appropriate time, temperature and pressure settings for the selected process

stages in the process for mould curing, removal and cooling

application of tools

sequence of procedures for release of master

placement of mould and vent lines.

Assessment Conditions

Assessors must:

have vocational competency in producing rubber moulds for lost wax casting process at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
