MEM04012B
Assemble plated patterns
Application
This unit applies to the assembly of all types of plated patterns using a range of materials such as timber, timber composite and metal. It covers the manufacture (when appropriate) and mounting of runner systems. This unit does not address machining competencies. If these are required, appropriate units should also be accessed. For cast aluminium plates, see Unit MEM04014B (Develop and manufacture production patterns). Where the manufacture of polymer-plated patterns is required, Unit MEM04011B (Produce polymer patterns) should also be accessed. Where precision measurement is required, Unit MEM12003B (Perform precision mechanical measurement) should also be considered. Band: A Unit Weight: 8 |

Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Determine job requirements | 1.1. Job instructions and specifications are correctly interpreted and followed. |
2. Inspect and layout patterns | 2.1. Pattern(s) are inspected to ensure dimensions and surface finish conform to specifications. 2.2. Pattern and runner system is laid out to specifications from drawings, sketches or verbal instructions. 2.3. Pattern(s) are correctly aligned. |
3. Mount pattern on plates | 3.1. Cope and drag patterns/double sided match plate patterns are attached to pattern plate/s according to specification. 3.2. Cope and drag patterns/double sided match plate patterns are inspected for security and alignment. |
4. Mount runner system | 4.1. Volume of runner system conforms to specification. 4.2. Runner components are attached to pattern plates using appropriate fixing and joining techniques to specification. |
5. Inspect plated pattern assembly | 5.1. Surface and mouldability of plated pattern assembly are inspected for compliance with specifications. |
Required Skills
Required skills |
Look for evidence that confirms skills in: determining job requirements from written instructions, specifications, sketches and drawings planning and sequencing tasks checking and clarifying task-related information performing relevant calculations following verbal instructions applying surface finishes for the moulding process laying out patterns and runner systems attaching pattern and runner components locating and aligning patterns checking patterns for compliance |
Required knowledge |
Look for evidence that confirms knowledge of: units of measurement, numerical operations and calculations associated with assembling plated patterns fixing and drilling techniques the reason for using particular layout and runner system types of pattern plates the techniques for avoiding cross jointing or mismatch of the pattern and their relationship to the pin-centre methoding systems mouldability i.e. surface finish, face taper, convex or concave perspectives, undercuts, etc. moulding and casting techniques use and application of personal protective equipment safe work practices and procedures hazards and control measures associated with assembling plated patterns |
Evidence Required
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 | A person who demonstrates competency in this unit must be able to assemble plated patterns. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with assembling plated patterns or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

Range Statement
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. | |
Aligned | Measurement and/or dowels |
Calculations | The determination of contraction rates as well as applicable general engineering calculations |
