Aluminum Anodizing Rack Load Capacity at 99% anodizing line uptime: a worked example

Push anodizing line uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a finishing planner needs to check whether anodizing capacity supports profile shipment dates

The inputs for this scenario

  • Profiles per rack cycle: 72 units / cycle (unchanged)
  • Available anodizing rack cycles: 24 cycles (unchanged)
  • Anodizing line uptime: 99 % (raised for this scenario; the documented default is 88)
  • Anodizing acceptance yield: 96 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross anodizing rack capacity = profiles per rack cycle × available anodizing rack cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,642 anodized profiles for usable anodizing rack capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,728 anodized profiles for gross anodizing rack capacity.
  • At this operating point the engine returns 17.28 anodized profiles for capacity lost to downtime.
  • At this operating point the engine returns 68.43 anodized profiles for profiles lost to anodizing rejects.

How this compares with the baseline

  • Against the tool's baseline example, where anodizing line uptime sits at 88% and the headline result is 1,460 anodized profiles, this scenario comes in 12.5% above the baseline at 1,642 anodized profiles.
  • It computes usable anodized profiles by taking gross rack capacity (profiles per cycle times available cycles) and multiplying by anodizing line uptime and acceptance yield. 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

  • Usable anodizing rack capacity: 1,642 anodized profiles (headline result)
  • Gross anodizing rack capacity: 1,728 anodized profiles
  • Capacity lost to downtime: 17.28 anodized profiles
  • Profiles lost to anodizing rejects: 68.43 anodized profiles
