Finishing worked example

Time at Temperature at 12% cure safety allowance: a worked example

This scenario runs the time at temperature calculation on the strong side: 12% cure safety allowance, with every other input held at its documented default. Use this calculator for practical powder coating or surface finishing planning, quoting, troubleshooting, or line setup.

The inputs for this scenario

  • Required time at metal temperature: 120 min (unchanged)
  • Achieved metal heating rate: 12 °F per min (unchanged)
  • Cure safety allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base time = required amount ÷ process rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 min for adjusted run time, the number this scenario is built around.
  • At this operating point the engine returns 10 min for base run time.
  • At this operating point the engine returns 12 % for allowance applied.
  • At this operating point the engine returns 12 pieces / min for process rate.

How this compares with the baseline

  • Against the tool's baseline example, where cure safety allowance sits at 10% and the headline result is 11 min, this scenario comes in 1.82% above the baseline at 11.2 min.
  • Use it to validate a cure recipe against the powder's time-at-temperature spec or when a line change alters heating rate. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Adjusted run time: 11.2 min (headline result)
  • Base run time: 10 min
  • Allowance applied: 12 %
  • Process rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Time at Temperature calculator, which recalculates instantly and can be shared with the inputs intact.
