Composite Cure Schedule Time at 11% ramp, monitoring, and demold allowance: a worked example

Suppose ramp, monitoring, and demold allowance falls to 11%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate total mold occupancy time for composite cure cycles based on number of cure stages, hours per stage, and allowances for temperature ramp, cool-down, and demold prep.

The inputs for this scenario

  • Number of cure stages: 3 stages (held at the documented default)
  • Average hours per cure stage: 8 hr / stage (held at the documented default)
  • Ramp, monitoring, and demold allowance: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base cure time = number of cure stages x average hours per stage.
  • Total mold occupancy for cure works out to 0.42 hr at these inputs, and this is the headline figure for the scenario.
  • Base cure cycle time works out to 0.38 hr at these inputs.
  • Ramp, monitoring, and demold hours works out to 11 % at these inputs.
  • Average cure rate per stage works out to 8 pieces / min at these inputs.

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 3.48% below the baseline at 0.42 hr.
  • It computes total mold occupancy for a cure by summing stage hours and adding an allowance for ramp, monitoring, and demold time. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total mold occupancy for cure: 0.42 hr (headline result)
  • Base cure cycle time: 0.38 hr
  • Ramp, monitoring, and demold hours: 11 %
  • Average cure rate per stage: 8 pieces / min
