Extrusion Runout Table Capacity Calculator at 99% runout table uptime: a worked example

Push runout table uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. a process engineer needs to check whether runout handling can keep up with the press and puller

The inputs for this scenario

  • Profiles handled per runout cycle: 14 units / cycle (unchanged)
  • Available runout handling cycles: 180 cycles (unchanged)
  • Runout table uptime: 99 % (raised for this scenario; the documented default is 90)
  • Accepted handling yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross runout handling capacity = profiles handled per cycle × available runout handling cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,420 profiles for usable runout table capacity, the number this scenario is built around.
  • At this operating point the engine returns 2,520 profiles for gross runout handling capacity.
  • At this operating point the engine returns 25.2 profiles for capacity lost to downtime.
  • At this operating point the engine returns 74.84 profiles for profiles lost to handling damage or rejects.

How this compares with the baseline

  • Against the tool's baseline example, where runout table uptime sits at 90% and the headline result is 2,200 profiles, this scenario comes in 10% above the baseline at 2,420 profiles.
  • It computes usable runout table throughput in profiles by derating gross handling capacity for table uptime and accepted handling 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 runout table capacity: 2,420 profiles (headline result)
  • Gross runout handling capacity: 2,520 profiles
  • Capacity lost to downtime: 25.2 profiles
  • Profiles lost to handling damage or rejects: 74.84 profiles
