Precision Springs, Stampings & Micro-Formed Components worked example

Heat Treat Load with heat treat load connected load of 30 kW: a worked example in precision springs, stampings & micro-formed components

What does the result look like when heat treat load connected load reaches 30 kW? The full calculation is worked below with real intermediate numbers. Use it when heat treat load in precision springs, stampings and micro-formed components is being quoted and energy is a real chunk of the precision springs, stampings and micro-formed components cost stack.

The inputs for this scenario

  • Heat treat load connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Heat treat load runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Units processed during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total heat treat load energy cost = heat treat load connected load × heat treat load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for heat treat load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total heat treat load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly heat treat load energy cost.

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 150% above the baseline at 240 kWh.
  • A figure at this level is achievable when heat treat load connected load is genuinely sustained, not just peaked for a shift. It assumes the furnace draws its full connected load for the whole runtime; real furnaces cycle between ramp and soak, so steady-state draw is often below nameplate and this can overstate energy.

Results at a glance

  • Heat treat load energy used: 240 kWh (headline result)
  • Total heat treat load energy cost: 28.8 $
  • Energy cost per kWh: 0.03 $ / piece
