Cold-End Inspection Capacity at 99% cold-end inspection uptime: a worked example

Push cold-end inspection uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when vision inspection, pressure testing, dimensional gauging, finish inspection, and manual quality checks must keep pace with lehr discharge and packing.

The inputs for this scenario

  • Containers inspected per inspection cycle: 420 containers / cycle (unchanged)
  • Available inspection cycles: 115 cycles (unchanged)
  • Cold-end inspection uptime: 99 % (raised for this scenario; the documented default is 93)
  • Inspection first-pass yield: 98 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross cold-end inspection capacity = containers inspected per cycle × available inspection cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 46,861 containers for good inspected-container capacity, the number this scenario is built around.
  • At this operating point the engine returns 48,300 containers for gross inspection capacity.
  • At this operating point the engine returns 483 containers for cold-end inspection uptime loss.
  • At this operating point the engine returns 956 containers for inspection yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where cold-end inspection uptime sits at 93% and the headline result is 44,021 containers, this scenario comes in 6.45% above the baseline at 46,861 containers.
  • It computes good inspected-container capacity as containers per cycle times available cycles, derated by inspection uptime and inspection first-pass 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

  • Good inspected-container capacity: 46,861 containers (headline result)
  • Gross inspection capacity: 48,300 containers
  • Cold-end inspection uptime loss: 483 containers
  • Inspection yield loss: 956 containers
