Powder Transfer Efficiency at 86% target transfer efficiency: a worked example

Push target transfer efficiency up to 86% and the picture changes. This example computes every intermediate figure at that operating point. Use to benchmark gun settings, grounding, part geometry, reclaim performance, and operator technique.

The inputs for this scenario

  • Powder deposited on parts: 42 lb (unchanged)
  • Powder sprayed from guns: 60 lb (unchanged)
  • Target transfer efficiency: 86 % (raised for this scenario; the documented default is 75)

Working through the calculation

  • Applying the documented formula (Transfer efficiency = powder deposited on parts รท powder sprayed) to the inputs above produces each figure below.
  • At this operating point the engine returns 70 % for rate, the number this scenario is built around.
  • At this operating point the engine returns 16 points for gap to target.
  • At this operating point the engine returns 42 count for affected count.
  • At this operating point the engine returns 60 count for total count.

How this compares with the baseline

  • Against the tool's baseline example, where target transfer efficiency sits at 75% and the headline result is 70 %, this scenario lands almost exactly on the baseline at 70 %.
  • It computes transfer efficiency as powder deposited on parts divided by powder sprayed, plus the point gap to your target. 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

  • Rate: 70 % (headline result)
  • Gap to target: 16 points
  • Affected count: 42 count
  • Total count: 60 count
