Application

This unit of competency defines the skills and knowledge required to produce one-off wax models.

This unit is not intended to include fine wire filigree work.

Where the use of computer aided equipment for modelling is required unit MEM09009 Create 2-D drawings using computer-aided design system and unit MEM09010 Create 3-D models using computer-aided design system, should also be selected as appropriate.

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, drawings, job sheets or work instructions and select appropriate method for construction of wax model for the supplied specifications

selecting wax to suit construction method and required finish and roughing out and sculpting shapes with minimal wastage, effort and time

fusing joints to achieve optimum strength and quality

conducting required measurements

applying texture finishing and inspecting and modifying product to achieve compliance with specifications.

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)

factors affecting construction of wax model, including type of wax, hand tools, method of construction, final finish and weight of finished product

variations in end product and the relationship with wax type

techniques in controlling melting wax and knowledge of effects of toxic fumes

tools for preparing and producing wax for specific wax types and constructions

importance of minimising material wastage and time taken during roughing and finishing and methods to be used to produce the required outcome to specifications with minimise waste

key features and datum points for model

purpose and requirements for selected surface finish

evaluation of product by weight formulation

effects of casting shrinkage and finishing processes.

Assessment Conditions

Assessors must:

have vocational competency in producing jewellery wax model 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.
