Plating, Anodizing & Surface Treatment worked example

Dwell Time at 12% setup, handling, and delay allowance: a worked example in plating, anodizing & surface treatment

This scenario runs the dwell time calculation on the strong side: 12% setup, handling, and delay allowance, with every other input held at its documented default. Use it when dwell time in plating, anodizing and surface treatment needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Parts to process in the bath: 120 units (unchanged)
  • Line throughput rate: 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when scheduling a lot into a shared tank line or reserving rack and operator time for a run. 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

  • Required dwell time: 11.2 hr (headline result)
  • Base dwell time: 10 hr
  • Dwell time allowance applied: 12 %
  • Dwell time completion rate: 12 pieces / min
