Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
A former used to give the required shape to the product and used under pressure. Dies are typically used in the extrusion, injection, blow moulding and general rubber sectors. Dies used which are not subject to pressure are referred to as 'moulds' in this Training Package.
Requirements for the die change may include checking the die dimensions such as mould height and required ejector stroke to ensure it is compatible with the selected machine
Basic numeracy is required, eg to monitor and set displays, gauges and dials to correct values according to set-up sheet.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

2.3 Attach replacement die ensuring that locating devices and marks are matched and securing devices are installed and tightened to specification.
This competency applies to advanced operators or operators who set dies in preparation for the production process. The job involves the die change and the setting of moulding conditions or program for the new die, and can include nozzle change, die tooling changing, screw cleaning and connection of ancillary equipment. The key factors are the safe, precise and efficient removal of dies and the correct installation and setting ready for production. It includes:
Setting of the machine conditions may include setting the mould height on the machine, the clamp force, the mould safety system, the ejector system, the mould opening and closing distances, speeds and forces and the injection unit.
Dies which use at least one external power and control source to actuate product forming components, which move in a direction other than the mould open axis, and require sequencing with the mould operation. Includes moulds which retain molten material within the mould between cycles. Typical features may include: hot runners; insulated runners; externally actuated sliding blocks, cores, and unscrewing systems; safety interlocks.
This competency covers the removal, refitting and setting of dies in preparation for production. It applies typically to the moulding areas of the industry such as injection moulding, and blow moulding.
For setting dies for extrusion, cablemaking and blown film, use PMBPREP305B Change extrusion die and calibration set -up . For changing moulds for rotational moulding or thermoforming, use PMBPROD282B Assemble mould . For quick change of dies, use MCMT220A Apply quick changeover procedures .

Plastic injection molding is a crucial industry in the world today. Plastic items are used in almost every aspect of life be it at home, schools, restaurants, or other industries. These items make work easier since they are low maintenance and very durable. This helps promote the green movement because the items can be used for a long time without the need for replacement, moreover, they are also recyclable.
People being trained in this unit who do not have an appropriate production or trade background may require extra time allowance.
These settings may be performed automatically, using an electronic storage device to load settings from a previous run of this product, or may be performed by manually setting controls individually.
They assist other companies in terms of design, product project development, sample build, product concept, production integration, first article report, mass production, and delivery of high-quality products and services. They have received a couple of rewards and recognition for their products and services.
A two plate die including any ejection system operating in the mould open axis, but excluding moulds with molten material retained within the mould between cycles. Products are simple, straight drawn items. Typical features may include: force, cavity, back plates, support plates, cold runner, sprue, nozzle seat, locating ring-tab, sub, fan, diaphragm and direct gating, ejector pins and sleeves, ejector plate and stripper plate, simple drilling for mould cooling.
Plastic injection molding is a manufacturing process used to obtain plastic products. It involves melting plastic pellets and once molten, is injected into a metal mold to make plastic items. The process uses pressure since molten plastic has a high viscosity and cannot be done manually. The most common plastic used is high or low-density polyethylene, however other types of plastics can also be utilized.
