Plastics Extrusion - Pipe, Film & Profile worked example

Line OEE at 66% line speed vs. rated haul-off rate: a worked example in plastics extrusion - pipe, film & profile

Here is what the math looks like when conditions slip. We hold every other input steady and drop line speed vs. rated haul-off rate to 66%, then walk the calculation through step by step. Estimate effective extrusion line OEE from operating time, planned time, performance, and quality yield.

The inputs for this scenario

  • Actual extrusion run time: 420 hr (held at the documented default)
  • Scheduled extrusion time: 480 hr (held at the documented default)
  • Line speed vs. rated haul-off rate: 66 % (the input this scenario stresses; the baseline uses 92)
  • First-pass quality yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Availability = operating time ÷ planned production time.
  • Extrusion line OEE works out to 56.02 % at these inputs, and this is the headline figure for the scenario.
  • Availability works out to 87.5 % at these inputs.
  • Performance versus standard works out to 66 % at these inputs.
  • Quality yield works out to 97 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line speed vs. rated haul-off rate sits at 92% and the headline result is 78.08 %, this scenario comes in 28.26% below the baseline at 56.02 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to line speed vs. rated haul-off rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. OEE hides where the loss lives — an 87.5% availability and 92% performance produce the same 80% factor product, so always review the three components separately, not just the headline number.

Results at a glance

  • Extrusion line OEE: 56.02 % (headline result)
  • Availability: 87.5 %
  • Performance versus standard: 66 %
  • Quality yield: 97 %
