Aluminum Extrusion & Profile Manufacturing worked example

Aluminum Aging Oven Load Capacity at 99% aging oven uptime: a worked example

What does the result look like when aging oven uptime reaches 99%? The full calculation is worked below with real intermediate numbers. a production manager needs to confirm whether aging capacity supports extrusion and shipment schedules

The inputs for this scenario

  • Profile bundles per aging cycle: 8 units / cycle (unchanged)
  • Available aging oven cycles: 30 cycles (unchanged)
  • Aging oven uptime: 99 % (raised for this scenario; the documented default is 92)
  • Post-aging acceptance yield: 98 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross aging oven capacity = profile bundles per cycle × available aging oven cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 233 aged loads for usable aging oven load capacity, the number this scenario is built around.
  • At this operating point the engine returns 240 aged loads for gross aging oven load capacity.
  • At this operating point the engine returns 2.4 aged loads for capacity lost to downtime.
  • At this operating point the engine returns 4.75 aged loads for loads lost to aging or hardness rejects.

How this compares with the baseline

  • Against the tool's baseline example, where aging oven uptime sits at 92% and the headline result is 216 aged loads, this scenario comes in 7.61% above the baseline at 233 aged loads.
  • A figure at this level is achievable when aging oven uptime is genuinely sustained, not just peaked for a shift. It assumes uniform cycle time per load; mixing alloys or wall thicknesses with different soak times will make a single cycle count inaccurate.

Results at a glance

  • Usable aging oven load capacity: 233 aged loads (headline result)
  • Gross aging oven load capacity: 240 aged loads
  • Capacity lost to downtime: 2.4 aged loads
  • Loads lost to aging or hardness rejects: 4.75 aged loads
