Precision Springs, Stampings & Micro-Formed Components worked example

Heat Treat Load with heat treat load connected load of 6 kW: a worked example in precision springs, stampings & micro-formed components

This worked example runs the heat treat load numbers for a tougher week than the baseline: heat treat load connected load of 6 kW instead of the typical 12 kW. Estimate heat treat load for precision springs, stampings and micro-formed components using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • Heat treat load connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Heat treat load runtime: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Units processed during runtime: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total heat treat load energy cost = heat treat load connected load × heat treat load runtime × blended electricity rate.
  • Heat treat load energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total heat treat load energy cost works out to 5.76 $ at these inputs.
  • Energy cost per kWh works out to 0.01 $ / piece at these inputs.
  • Hourly heat treat load energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where heat treat load connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • Use it when costing a heat-treat step, comparing furnace cycles, or estimating the energy footprint of a stress-relief batch. 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

  • Heat treat load energy used: 48 kWh (headline result)
