Rubber, Tires, Foam & Elastomer Manufacturing worked example

Rubber Aging Loss at 99% aging oven uptime: a worked example

Push aging oven uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when rubber aging loss in rubber, tires, foam and elastomer manufacturing is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Cured parts produced per aging cycle: 4 units / cycle (unchanged)
  • Aging cycles available in the period: 480 cycles (unchanged)
  • Aging oven uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass yield after aging inspection: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross rubber aging loss capacity = rubber aging loss output per cycle × available rubber aging loss cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good rubber aging loss capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross rubber aging loss capacity.
  • At this operating point the engine returns 19.2 units for rubber aging loss downtime loss.
  • At this operating point the engine returns 57.02 units for rubber aging loss yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where aging oven uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • It computes good post-aging capacity by taking gross oven capacity and derating it for oven uptime and first-pass yield, while breaking out downtime loss and yield loss separately. 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 rubber aging loss capacity: 1,844 units (headline result)
