Cure Oven Energy Cost with oven or heated tool connected load of 48 kW: a worked example in composites, fiberglass & advanced materials

This worked example runs the cure oven energy cost numbers for a tougher week than the baseline: oven or heated tool connected load of 48 kW instead of the typical 95 kW. Estimate energy cost per composite part for oven, hot box, or heated tool curing.

The inputs for this scenario

  • Oven or heated tool connected load: 48 kW (the input this scenario stresses; the baseline uses 95)
  • Cure cycle runtime: 7.5 hr (held at the documented default)
  • Energy price: 0.14 $ / kWh (held at the documented default)
  • Good parts processed in the cure batch: 24 parts (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Batch energy cost = oven or heated tool connected load × cure cycle runtime × electric or gas energy price.
  • Total cure oven energy cost works out to 24.5 $ / part at these inputs, and this is the headline figure for the scenario.
  • Cure oven energy cost per unit works out to 0.51 $ / piece at these inputs.
  • Variable cure oven energy cost works out to 0.5 $ at these inputs.
  • Fixed cure oven energy cost adder works out to 24 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where oven or heated tool connected load sits at 95 kW and the headline result is 25 $ / part, this scenario comes in 1.97% below the baseline at 24.5 $ / part.
  • Use it when quoting parts, evaluating whether to consolidate cure batches, or comparing the energy cost of different cure profiles or oven assets. 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

  • Total cure oven energy cost: 24.5 $ / part (headline result)
  • Cure oven energy cost per unit: 0.51 $ / piece
  • Variable cure oven energy cost: 0.5 $
  • Fixed cure oven energy cost adder: 24 $
