Batch Cure Time at 21% cure handling allowance: a worked example

This scenario runs the batch cure time calculation on the strong side: 21% cure handling allowance, with every other input held at its documented default. Use it when scheduling compression molding, transfer molding, oven post-cure, silicone bakeout, or batch curing for gaskets, seals, O-rings, diaphragms, and custom rubber parts.

The inputs for this scenario

  • Batch cure workload: 960 parts (unchanged)
  • Cure processing rate: 240 parts / hr (unchanged)
  • Cure handling allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base batch cure time = batch cure workload รท cure processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 4.84 hr for required batch cure time, the number this scenario is built around.
  • At this operating point the engine returns 4 hr for base batch cure time.
  • At this operating point the engine returns 21 % for cure handling allowance.
  • At this operating point the engine returns 240 pieces / min for cure processing rate.

How this compares with the baseline

  • Against the tool's baseline example, where cure handling allowance sits at 18% and the headline result is 4.72 hr, this scenario comes in 2.54% above the baseline at 4.84 hr.
  • Use it when scheduling cure-cell capacity, sequencing batches through ovens or autoclaves, or quoting lead time on a molded seal order. 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

  • Required batch cure time: 4.84 hr (headline result)
  • Base batch cure time: 4 hr
  • Cure handling allowance: 21 %
  • Cure processing rate: 240 pieces / min
