Heat Exchanger, Coil & Radiator Manufacturing worked example

Assembly Takt with net available coil assembly time of 230 min / shift: a worked example in heat exchanger, coil & radiator manufacturing

Suppose net available coil assembly time falls to 230 min / shift. This page works the full calculation at that level so you can see exactly which result moves and by how much. Find the takt time for Heat Exchanger, Coil & Radiator Manufacturing — the pace, in seconds per unit, that production must hold to exactly meet customer demand.

The inputs for this scenario

  • Net available coil assembly time: 230 min / shift (the input this scenario stresses; the baseline uses 450)
  • Customer coil demand: 60 units / shift (held at the documented default)
  • Shifts per day: 2 shifts (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Takt time = net available production time × 60 ÷ customer demand.
  • Takt time works out to 230 sec / unit at these inputs, and this is the headline figure for the scenario.
  • Required rate works out to 15.65 units / hr at these inputs.
  • Available time / day works out to 460 min at these inputs.
  • Demand / day works out to 120 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where net available coil assembly time sits at 450 min / shift and the headline result is 450 sec / unit, this scenario comes in 48.89% below the baseline at 230 sec / unit.
  • It computes takt time in seconds per unit from net available production time and customer demand, and the required hourly build rate that the line must hold. 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

  • Takt time: 230 sec / unit (headline result)
