Design and prepare models, moulds and dies

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency applies to technicians or tradespeople who are responsible for determining the requirements for devices to be made from plans, specifications and schedules. Technicians are able to make the device from materials selected and adjust and check its dimensional accuracy. Often the devices are made from timber, but other materials, including sheet metal and fibreglass, for instance are possible.

This unit of competency covers the making of moulds, models and dies for use in a variety of manufacturing operations, such as:

concrete products

clay products

ceramic products

This unit was developed for larger production contexts but it may also be relevant to craft practitioners producing ceramic work.

This competency is typically performed by an experienced technician, leading hand or supervisor.

This unit of competency covers the design and preparation of models, moulds, and dies, and includes the preparation of cases and frames.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:

OHS requirements are met

quality improvement techniques are applied

emergency procedures are understood and applied

waste is minimised.

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

This unit has no prerequisite competencies.

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

using and maintaining all required materials, tools and parts

recognising situations which could cause production problems and taking appropriate action

implementing enterprise's procedures and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of moulds and dies

diagnosing and solving problems involved in the work

predicting hazards that may arise from mould or die design or preparation

communicating effectively with team members, management and other departments

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

specified quality standards

characteristics of different materials

requirements from drawings, specifications or job sheets

distinguish between causes of faults such as:

materials

dimensions

allowance for shrinkage

damage to components

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Procedures

All operations are performed in accordance with standard procedures and work instructions

Materials

Materials may include:

additives

body materials

epoxy resins

metal strapping

plaster

plastic

release agents

rubber

slip

timber

water

Equipment

Equipment may include:

block moulds and working moulds

cases and frames

hand and power tools

jigs and fixtures

master dies

mixing equipment

models

weighing equipment

OHS

The identification and control of hazards and the application of OHS are to be in accordance with current, applicable legislation and regulations, and company procedures. All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
