Job Task Planning and Organizing

Plastics processing machine operators perform repetitive tasks, operating and maintaining machines and packaging products. The order and priority of job tasks are usually determined by supervisors who create the production schedules. Operators have some flexibility in determining the order of tasks, provided that deadlines are met. They co-ordinate their tasks with co-workers, such as those who produce the raw materials for the machines. Machine malfunctions, rush jobs or line breaks may interrupt the flow of work and lead to operators adjusting their priorities, in conjunction with their supervisors. Operators must organize their tasks effectively to respond to several needs at the same time.

Significant Use of Memory
  • Remember the sequence of steps in machine setup when changing production runs.
  • Remember how fast individual machines run and at what temperature.
  • Remember troubleshooting procedures for solving problems with machines.
Finding Information
  • Consult machine manufacturers to find out how to program changes on computerized machinery. (1)
  • Refer to specification sheets to learn about materials, part sizes and tolerances for parts produced on machines. (1)
  • Consult production schedules to obtain information on which machines will be used to produce different products. (2)
  • Refer to machine manuals to troubleshoot or set up machines for new products. (2)

Working with Others

Plastics processing machine operators mainly work independently. They may work with a partner when doing preventive maintenance on machines or lifting materials and moulds. Although they all have their individual jobs, they form a team with other members of their shift.

Continuous Learning

Plastics processing machine operators continue to learn. They take first aid training and other safety related courses. They learn about new machinery and production procedures on the job through interaction with co-workers and supervisors.
