Extrusion Operator II (Press Operator) (Project Management)
1. Responsible for the safe and efficient running of the extrusion press. 1.1. Setting and removing die from die cassette. 1.2 Set up press for each new die using the shop order, standard practice, and die card history.(Billet length, billet temperature, puller torque, press speed, extrusion ratio) 1.3 Closely monitor all activity from the furnace door through the transfer of extruded billet to cooling table to prevent potential problems. 1.4 Coordinate alloy changes with the extrusion material handler. 1.5 Responsible for filling Billet Saw Oil Canister.
2. Visually monitor extrusions for quality. 2.1 Assist utility inspector with monitoring of exit temperature. 2.2 Periodically check extrusion for tearing, die lines, streaks, or other defects. 2.3 Watch cooling table for problems caused by puller torque or cooling fans.
3. Responsible for the in-process inspection/verification of parts during extrusion. 3.1 Verify press speed, billet temperature, and puller torque are set as required by the die card. 3.2 Verify extrusion is set-up correctly at press exit. (No bolster rubs, no carbon marks, and parts are adequately supported and separated) 3.3 Verify exit temperature meets minimum for given alloy according to posted chart. 3.4 Sample, inspect, and document initial part from start of run and periodically as required. 3.5 Inform Team Lead of any dimensional or surface discrepancies.
4. Responsible for inspecting parts after the stretching operation. 4.1 Monitor dimensions and surface after the stretch as the stretching process may change the parts dimensions. 4.2 Inform Team Lead of any changes or problems after stretch.
5. Responsible for relieving Press Team for breaks and lunch.
6. Responsible for periodic rack and length checks. 6.1. Periodically verify that parts are being properly racked as to not cause any damage. 6.2. Verify parts are being cut to the proper length. 6.3. Verify the blade is not leaving an excessive burr.
7. Monitor and maintain good physical condition of extrusion press and handling equipment. 7.1. Maintain adequate lubrication on end of billet, fixed head, and container face to prevent excess build up of aluminum. 7.2. Visually inspect press and handling equipment for any issues that maintenance needs to address. 7.3. Inform maintenance and supervisor of any equipment that does not seem to be functioning properly. 7.4. Maintain a clean and safe work area. 7.5. Listening during extrusion for things like butts dropping properly and water/air running appropriately.
