Description
This unit covers preparing equipment for die casting, manually pouring the metal, removing the material and cleaning the die.
Notes
Elements and Performance Criteria
1. Prepare equipment
  • 1.1. Die coat is mixed in correct proportion.
  • 1.2. Die temperatures are lifted to, or maintained, at the correct level.
  • 1.3. Appropriate safety clothing and apparatus is used.
  • 1.4. Die coat is applied in correct sequence and in a safe manner according to standard operating procedures.
  • 1.5. Die is correctly located and closed.
  • 1.6. Die is correctly placed on machine, toggle clamps are attached and done up to required torque.
  • 1.7. Air cooling is attached to the die as specified if required.
2. Carry out manual pouring
  • 2.1. Pour is made in manner to reduce porosity and lamination.
  • 2.2. Conditions are identified that contribute to inferior castings or rejects.
  • 2.3. Allowance is made for adequate cooling time.
  • 2.4. Pour is made at a continuous and appropriate rate during filling.
  • 2.5. Monitoring of die coating condition is carried out and re-spraying occurs as required.
3. Remove materials
  • 3.1. Parts are removed and stored in a manner that minimises damage. Any flash is removed from the die surface.
4. Clean die
  • 4.1. Shot blaster is operated in a safe manner and according to standard operating procedures.
  • 4.2. Chemical analysis of melt is taken and remedial action is applied as required to standard operating procedures.
  • 4.3. Furnace is drossed and/or degassed to standard operating procedures.
  • 4.4. Work area is cleaned of coating and shot residue to appropriate standard.
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.
Correct proportions
Will be determined by manufacturer specifications
Die temperatures
Will vary according to standard operating procedures and/or organisation's procedures
Appropriate safety clothing and apparatus
Aluminium Association safety status sheet recommendations, glasses, aluminised suits, masks, gloves, gauntlet, etc.
EVIDENCE GUIDE
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 undertake gravity die casting. 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. Where assessment occurs off the job, i.e. the candidate is not in productive work, 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 gravity die casting 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.
