Rubber, Tires, Foam & Elastomer Manufacturing worked example

Banbury Mixer Capacity at 65% banbury mixer availability: a worked example

This worked example runs the banbury mixer capacity numbers for a tougher week than the baseline: 65% banbury mixer availability instead of the typical 90%. Estimate banbury mixer capacity for rubber, tires, foam and elastomer manufacturing using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Compound batch weight per mixer cycle: 4 units / cycle (held at the documented default)
  • Available Banbury mixer cycles per shift: 480 cycles (held at the documented default)
  • Banbury mixer availability (uptime): 65 % (the input this scenario stresses; the baseline uses 90)
  • Batch acceptance (first-pass) rate: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross banbury mixer capacity = banbury mixer capacity output per cycle × available banbury mixer capacity cycles.
  • Good banbury mixer capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross banbury mixer capacity works out to 1,920 units at these inputs.
  • Banbury mixer capacity downtime loss works out to 672 units at these inputs.
  • Banbury mixer capacity yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where banbury mixer availability sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • Use it to plan a shift's compound supply, size mixer capacity against downstream demand, or quantify the output cost of mixer downtime. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Good banbury mixer capacity: 1,211 units (headline result)
  • Gross banbury mixer capacity: 1,920 units
  • Banbury mixer capacity downtime loss: 672 units
  • Banbury mixer capacity yield loss: 37.44 units
