Unit of Competency MSATCM403A - Evaluate mould design and gating
Description This unit covers the knowledge and skills needed to evaluate mould design, gating, running and feeding of castings (known as methoding) including understanding the solidification process and techniques to eliminate defects to meet specified quality requirements.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application In a typical scenario, a metallurgical technician will be required to examine a mould design and draw some conclusions as to the appropriateness of gating, running and feeding design, or alternatively make some recommendations as to design.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to evaluate mould design and gating. Critical aspects for assessment and evidence are required to demonstrate competency in this unit.

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

It is essential that competence is demonstrated in the ability to:

Calculate manually and by use of computer programs runner and feeding systems for casting designs. Evidence must be provided of manual calculations and compared to computer program results.

Evaluate mould designs. Evidence should be provided from the evaluation of a number of moulds.

Understand the interplay between moulds, cores, gating and feeding

Evaluate the resulting casting for success of gating and feeding

Compare casting results with computer simulated predictions.

Relationship to other units

This unit may be assessed concurrently with other relevant units.

Assessment method and context

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the elements, performance criteria, skills and knowledge. A holistic approach should be taken to the assessment.

Assessors should gather sufficient, fair, valid, reliable, authentic and current evidence from a range of sources. Sources of evidence may include direct observation, reports from supervisors, peers and colleagues, project work, samples, organisation records and questioning. Assessment should not require language, literacy or numeracy skills beyond those required for the unit.

The assessee will have access to all techniques, procedures, information, resources and aids which would normally be available in the workplace.

The method of assessment should be discussed and agreed with the assessee prior to the commencement of assessment.

Resource implications

This section should be read in conjunction with the range of variables for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

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.

This describes the essential skills and knowledge and their level, required for this unit.

Required skills:

Apply scientific principles to foundry mould design

Evaluate mould design to suit specific applications

Calculate mould runner and feeding systems

Select appropriate techniques and associated software and hardware technologies to suit specific applications in foundry mould design

Present solutions and any associated limitations referring to the original aim of the application.

Required knowledge:

Solidification

Nucleation

Growth mechanisms (crystal and interfacial)

Dendrite coherency

Constitutional undercooling

Superheat

Eutectic and peritectic solidification

Grain Structure

Running, Gating and Feeding

Terminology

Runner and gating principles (ratios)

Pouring basin or cup

Sprue design

Runner design

Ingate design

Inclusion control (slag, erosion, etc)

Metal flow (lamellar and turbulent), velocity and temperature

Modulus principle (calculation of feeder size)

Location of feeders (end and feed zones, neighbourhood effect, feeding distances)

Exothermic and insulating feeding aids (sleeves and topping)

Feeding mechanisms (liquid, mass, interdendritic, burst&solid)

Computer packages (runner and feeder calculations, mould simulations)

Yield calculations

Defect Formation

Shrinkage

Porosity

Segregation

Hot Tearing

Shear

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.

Codes of practice/standards

Where reference is made to industry codes of practice, and/or Australian/international standards, it is expected the latest version will be used.

Size and number of feeder heads and gating

Calculation of the size of feeder heads and gating includes manual calculation and use of computer programs

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.
