Plating, Anodizing & Surface Treatment worked example

Line Throughput at 65% line uptime: a worked example in plating, anodizing & surface treatment

Here is what the math looks like when conditions slip. We hold every other input steady and drop line uptime to 65%, then walk the calculation through step by step. Estimate line throughput for plating, anodizing and surface treatment using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Parts loaded per rack or barrel cycle: 4 units / cycle (held at the documented default)
  • Available process cycles per shift: 480 cycles (held at the documented default)
  • Line uptime (running vs. scheduled): 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass yield off the line: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross line throughput capacity = line throughput output per cycle × available line throughput cycles.
  • Good line throughput capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross line throughput capacity works out to 1,920 units at these inputs.
  • Line throughput downtime loss works out to 672 units at these inputs.
  • Line throughput yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to line uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes uptime and yield are independent and steady; a line that degrades yield as it speeds up, or clusters downtime into long outages, will behave differently than the flat multipliers suggest.

Results at a glance

  • Good line throughput capacity: 1,211 units (headline result)
  • Gross line throughput capacity: 1,920 units
  • Line throughput downtime loss: 672 units
  • Line throughput yield loss: 37.44 units
