Unit of Competency | PMAOPS211B - Operate manufacturing extruders |
---|---|---|---|
Description | This unit covers the operation of extruders which produce plastic granules/pellets from polymer resin and similar extrusions, eg powder coating resin. It includes the operation of equipment ancillary to the extruder, including that used for adding masterbatch and other additives. | ||
Employability Skills | This unit contains employability skills. | ||
Learning Outcomes and Application | In this competency, the operator would operate an extruder and its associated equipment, such as the input and output feeder systems or cooling systems. This includes starting up and shutting down the system, building the extrusion rate up correctly after start up, and then monitoring the system to maintain the required output rate and quality. This requires the operator to have a good understanding of the effect of adjustments (eg barrel temperature) on the extrusion process. The operator would make appropriate adjustments as required to ensure the product quality meets specifications, output meets schedule and to minimise potential problems with the process.In this competency, the operator would:make changes to the extruder system such as change the production rate or change the specifications of the output productperform cleaning and minor maintenance on the extruder system in accordance with proceduresidentify and control hazards related to manufacturing extruders and surrounding areas.Generally the operator would be part of a team during start up and shut down procedures and would be expected to be capable of demonstrating competence in all parts of this unit. At all times they would be liaising and cooperating with other members of the team. | ||
