Rubber, Tires, Foam & Elastomer Manufacturing worked example

Mold Cavity Output at 99% expected press uptime: a worked example

This scenario runs the mold cavity output calculation on the strong side: 99% expected press uptime, with every other input held at its documented default. Use it when mold cavity output 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

  • Parts per mold cycle (cavities): 4 units / cycle (unchanged)
  • Scheduled press cycles available: 480 cycles (unchanged)
  • Expected press uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected first-pass yield: 97 % (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where expected press uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it to plan realistic mold capacity, size a run, or diagnose whether output shortfalls come from downtime or from yield. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good mold cavity output capacity: 1,844 units (headline result)
