Extruded Profile Packaging Length Count at 65% packaging station uptime: a worked example

Suppose packaging station uptime falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate usable packaged profile length from bundle length per cycle, packaging cycles, packing uptime, and accepted packaging yield.

The inputs for this scenario

  • Profile length packed per cycle: 480 ft / cycle (held at the documented default)
  • Available packaging cycles: 18 cycles (held at the documented default)
  • Packaging station uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Accepted packaged-length yield: 98 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross packaged profile length = profile length packed per cycle × available packaging cycles.
  • Usable packaged profile length works out to 5,504 packaged ft at these inputs, and this is the headline figure for the scenario.
  • Gross packaged profile length works out to 8,640 packaged ft at these inputs.
  • Length lost to packaging downtime works out to 3,024 packaged ft at these inputs.
  • Length lost to packaging damage or rejects works out to 112 packaged ft at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where packaging station uptime sits at 90% and the headline result is 7,620 packaged ft, this scenario comes in 27.78% below the baseline at 5,504 packaged ft.
  • It computes usable packaged profile length by multiplying length packed per cycle by available cycles, then by packaging station uptime and accepted-length yield. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Usable packaged profile length: 5,504 packaged ft (headline result)
  • Gross packaged profile length: 8,640 packaged ft
  • Length lost to packaging downtime: 3,024 packaged ft
  • Length lost to packaging damage or rejects: 112 packaged ft
