Thermoforming & Vacuum Formed Products worked example

Line Throughput at 65% line performance efficiency: a worked example in thermoforming & vacuum formed products

This worked example runs the line throughput numbers for a tougher week than the baseline: 65% line performance efficiency instead of the typical 90%. Thermoforming line throughput is the heartbeat metric of a forming operation: it tells you how many good parts per hour the line actually delivers, not what the machine nameplate claims.

The inputs for this scenario

  • Good parts completed in the run: 1,200 units (held at the documented default)
  • Actual line run time: 8 hr (held at the documented default)
  • Line performance efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw line throughput = completed output รท runtime.
  • Effective throughput works out to 97.5 units / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units / hr at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line performance efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 27.78% below the baseline at 97.5 units / hr.
  • Use it when pacing a run, checking whether a line can meet an order in the hours available, or comparing actual rate to standard. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Effective throughput: 97.5 units / hr (headline result)
  • Raw throughput: 150 units / hr
  • Efficiency: 65 %
  • Runtime: 8 hr
