Injection Molding worked example
Mold Changeover Cost with changeover time of 1.25 hrs: a worked example in injection molding
Suppose changeover time falls to 1.25 hrs. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the cost of a mold changeover from downtime duration, press hourly rate, and labor cost for setup technicians.
The inputs for this scenario
- Changeover time (mold swap duration): 1.25 hrs (the input this scenario stresses; the baseline uses 2.5)
- Press hourly rate (with overhead): 125 $/hr (held at the documented default)
- Setup labor rate (crew cost): 70 $/hr (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Changeover cost = Changeover time x (Press rate + Labor rate).
- Result works out to 10,938 $ at these inputs, and this is the headline figure for the scenario.
- Combined hourly rate (press + labor) works out to 10,938 value at these inputs.
- Multiplier works out to 1 x at these inputs.
- Factor A x B works out to 156 value at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where changeover time sits at 2.5 hrs and the headline result is 21,875 $, this scenario comes in 50% below the baseline at 10,938 $.
- It calculates the cost of a single mold changeover from the swap duration, the fully loaded press rate, and the setup crew labor rate. 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.
