In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard is for people who work, or intend to work in a manufacturing process or similar environment where foundry moulds are required for the metal product casting process. The skills, knowledge and values reflected in this unit standard will contribute towards the achievement of a National Certificate in Foundry Operations at NQF Level 4. Equipment operated in this unit standard is against a set of specific instructions.

People credited with this unit standard are able to:
  • Plan to produce strickle mould.
  • Prepare work area for strickle mould production.
  • Produce cope and drag mould.
  • Finish strickle mould.
  • Close strickle mould.
  • Clamp and secure strickle mould. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credits allocated to this unit standard assume that the learner has a National Certificate in Foundry Operations NQF Level 3 or an equivalent qualification. It also assume that the learner is working towards a qualification as part of a learning programme, which integrates all the required unit standards.

    The learning time will increase if the learner does not have:
  • A relevant NQF 3 qualification.
  • Experience in a relevant field.
  • Demonstrated competence in the interpretation of technical drawings and method cards.
  • Demonstrated competence in producing moulds using loose patterns.
  • Relevant quality awareness principles and procedures.

    The learning time will be decreased if the learner has experience in this field because:
  • The learning programme will be adjusted to build on what the learner already knows.
  • The learner can apply to have prior learning recognised. 
    		•
