Design and construct moulds for fibrous plaster products

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Reference books for 'Design and construct moulds for fibrous plaster products' on This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to for every purchase, so go nuts :)

Elements and Performance Criteria



1. Develop mould design

1.1. Establish original product concept or design from drawings, originals or consultation with the customer

1.2. Sketch out product prototype design and establish product sizes making appropriate allowance for material shrinkage

1.3. Identify areas where undercuts, cutbacks or other special features are required

1.4. Determine parting line

1.5. Determine material from which mould is to be made

2. Select mould material and prepare for mould production

2.1. Set up material for mould making, ensuring that the mould can be handled or moved without damage

2.2. Establish datum point and mark out design dimensions using geometric and lineal calculations

2.3. Determine correct cavity depths and contours

2.4. Ensure there is adequate ventilation and light to facilitate an appropriate work environment

3. Produce working mould

3.1. Fit appropriate protective equipment to prevent inhalation or irritation of by-products of the mould making process

3.2. Use appropriate tools to carve out mould cavity and detail

3.3. Accurately follow the design detail to produce a mould cavity to specification

3.4. Avoid undercuts which will prevent removal of the plaster product from the mould

3.5. Ensure appropriate degrees of taper are provided to facilitate product removal

3.6. Carve reliefs according to design and remove debris as the work proceeds

4. Complete mould

4.1. Clean down completed mould and clean up work area

4.2. Inspect mould surface for defects or irregularities

4.3. Compare design details with mould cavity to confirm accuracy of translation

4.4. Coat mould surface to preserve finish and allow to dry

5. Produce product prototype

5.1. Apply slipping agent to mould surface

5.2. Prepare and insert anchors or ties

5.3. Prepare plaster mixture and appropriate amount of glass fibre

5.4. Cast plaster mix and fibre into mould cavity, strike off and allow to set

5.5. Remove prototype from mould or mould from prototype

5.6. Check prototype for dimensional and detail accuracy

5.7. Compare prototype and mould to identify any faults or mould inaccuracies

5.8. Adjust or dress mould to remove imperfections and clean mould surface

5.9. Cast second prototype and recheck product and mould

5.10. Clean up mould and mark in accordance with organisation identification practice

6. Control hazards

6.1. Identify hazards in modelling work area

6.2. Assess the risks arising from those hazards

6.3. Implement measures to control those risks in line with procedures and duty of care

7. Respond to problems

7.1. Identify possible routine and non-routine problems in the equipment or process

7.2. Determine problems needing action

7.3. Determine possible fault causes

7.4. Rectify problem using appropriate solution within area of responsibility

7.5. Report problems outside area of responsibility to designated person
