Adhesive Changeover Time at 46% purge and cleaning allowance: a worked example

Push purge and cleaning allowance up to 46% and the picture changes. This example computes every intermediate figure at that operating point. a production scheduler needs to plan downtime for adhesive or sealant changeovers

The inputs for this scenario

  • Adhesive changeovers: 7 changeovers (unchanged)
  • Changeover completion pace: 0.06 changeovers/min (unchanged)
  • Purge/cleaning allowance: 46 % (raised for this scenario; the documented default is 40)

Working through the calculation

  • Applying the documented formula (Base changeover time = adhesive changeovers รท changeover completion pace) to the inputs above produces each figure below.
  • At this operating point the engine returns 170 hr for adhesive changeover workload, the number this scenario is built around.
  • At this operating point the engine returns 117 hr for base changeover time.
  • At this operating point the engine returns 46 % for purge/cleaning allowance.
  • At this operating point the engine returns 0.06 changeovers/min for changeover completion pace.

How this compares with the baseline

  • Against the tool's baseline example, where purge and cleaning allowance sits at 40% and the headline result is 163 hr, this scenario comes in 4.29% above the baseline at 170 hr.
  • It computes total adhesive changeover labor hours by dividing changeovers by your completion pace, then adding a purge and cleaning allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Adhesive changeover workload: 170 hr (headline result)
  • Base changeover time: 117 hr
  • Purge/cleaning allowance: 46 %
  • Changeover completion pace: 0.06 changeovers/min
