Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Regulatory framework

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used.

Applicable legislation, regulations, standards and codes of practice include:

health, safety and environmental (HSE) legislation, regulations and codes of practice relevant to the workplace, manual handling and hazardous materials

Australian/international standards relevant to the materials being used and products being made

any relevant licence and certification requirements.

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence.

Procedures

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, and include one or any combination of:

technical specifications

technical drawings

emergency procedures

work instructions

standard operating procedures (SOPs)

safe work method statements (SWMS)

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant.

Die

A die is a former used to give shape to the product and used under pressure. Dies are typically used in the extrusion, injection, blow moulding and general rubber sectors.

Dies which are not subject to pressure are referred to as 'moulds' in this Training Package.

Advanced die

An advanced die is a two or three plate die which has one or more product forming components which:

move in a direction other than the mould open axis

are driven by the mould rather than external actuation.

An advanced die will typically feature one or more of:

sliding blocks or cores actuated by skew pins or cams

baffled, spiral, tube, and heat pipe cooling systems

rising cores

internally actuated unscrewing systems.

Complex die

A complex die is either:

a die which has one or more product forming components that:

use an external power and control source to actuate product forming components

move in a direction other than the mould open axis

require sequencing with the mould operation

a mould which retains molten material within the mould between cycles.

A complex die will typically feature one or more of:

hot runners

insulated runners

externally actuated sliding blocks, cores and unscrewing systems

safety interlocks.

Tools and equipment

Tools and equipment include:

dies/tools

ancillary equipment, including one or more of:

hot-runner temperature control

hydraulic or pneumatic power supply for actuation of equipment, such as cores or sliding blocks

mould temperature control

hand/power tools used in this process.

Additional tools and equipment will be selected as required from:

hoists/lifting equipment not requiring any special permits or licences

manual handling, aids such as hand carts and trolleys

relevant personal protective equipment (PPE).

Hazards

Hazards must be identified and controlled. Identifying hazards requires consideration of:

weight, shape, volume of materials to be handled

hazardous products and materials

rotational equipment or vibration

sharp edges, protrusions or obstructions

slippery surfaces, spills or leaks

smoke, dust or other atmospheric hazards

high temperatures

electricity

gas

gases and liquids under pressure

structural hazards

equipment failures

machinery, equipment and product mass

other hazards that might arise.
