Description
This unit of competency covers the skills and knowledge required to remove and refit dies, pins, sizing dies (calibrator), vacuum blocks and seals as used in extrusion line processes.This unit of competency is typically performed by experienced operators or those in similar roles who are required to plan and prepare the change, select dies that match product/process specification, make the changeover and test the changeover, and fine tune settings to meet specifications.This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members, team leader and supervisor, as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.
