Composite Cure Schedule Time at 17% ramp, monitoring, and demold allowance: a worked example

This scenario runs the composite cure schedule time calculation on the strong side: 17% ramp, monitoring, and demold allowance, with every other input held at its documented default. Use it when scheduling mold usage in a composite boat shop to determine how long a hull or deck part ties up the mold during curing.

The inputs for this scenario

  • Number of cure stages: 3 stages (unchanged)
  • Average hours per cure stage: 8 hr / stage (unchanged)
  • Ramp, monitoring, and demold allowance: 17 % (raised for this scenario; the documented default is 15)

Working through the calculation

  • Applying the documented formula (Base cure time = number of cure stages x average hours per stage) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.44 hr for total mold occupancy for cure, the number this scenario is built around.
  • At this operating point the engine returns 0.38 hr for base cure cycle time.
  • At this operating point the engine returns 17 % for ramp, monitoring, and demold hours.
  • At this operating point the engine returns 8 pieces / min for average cure rate per stage.

How this compares with the baseline

  • Against the tool's baseline example, where ramp, monitoring, and demold allowance sits at 15% and the headline result is 0.43 hr, this scenario comes in 1.74% above the baseline at 0.44 hr.
  • Use it when scheduling mold cycles, sizing how many parts a mold can produce per week, or comparing cure recipes for throughput. 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

  • Total mold occupancy for cure: 0.44 hr (headline result)
  • Base cure cycle time: 0.38 hr
  • Ramp, monitoring, and demold hours: 17 %
  • Average cure rate per stage: 8 pieces / min
