Finishing worked example
Coating Line Bottleneck at 12% downtime & handling allowance: a worked example
This scenario runs the coating line bottleneck calculation on the strong side: 12% downtime & handling 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
- Stage throughput required (parts or line ft): 120 ft or parts (unchanged)
- Conveyor / stage process rate: 12 ft / min (unchanged)
- Downtime & handling allowance: 12 % (raised for this scenario; the documented default is 10)
Working through the calculation
- Applying the documented formula (Base time = required amount รท process rate) to the inputs above produces each figure below.
- At this operating point the engine returns 11.2 parts / hr for adjusted run time, the number this scenario is built around.
- At this operating point the engine returns 10 parts / hr 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 downtime & handling allowance sits at 10% and the headline result is 11 parts / hr, this scenario comes in 1.82% above the baseline at 11.2 parts / hr.
- Use it when balancing a monorail or power-and-free line, sizing booth capacity, or deciding which stage to speed up. 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 parts / hr (headline result)
