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 5. Equipment operated in this unit standard is against a set of specific instructions.

People credited with this unit standard are able to:
  • Determine the requirements for metal casting.
  • Design casting process for making casting.
  • Evaluate casting process.
  • Establish casting process and work plans. 
    		•

    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 4 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 Level 4 qualification.
  • Experience in a relevant field.
  • Demonstrated competence in the interpretation of technical drawings and method cards.
  • Demonstrated competence in producing complex moulds.

    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. 
    		•

    UNIT STANDARD RANGE 
    The scope and level of this unit standard is indicated by range statements related to the specific outcomes:
  • Developing casting processes covers both ferrous and non-ferrous metal processes.
  • Planning knowledge includes but is not limited to planning methods, identifying production constraints and taking corrective action.
  • Production constraints include shortage of consumables, delays in core production, delays in molten metal availability, lack of space on foundry floor, crane delay.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
