Mold Life Economics at 75% mold cost allocation share: a worked example

What does the result look like when mold cost allocation share reaches 75%? The full calculation is worked below with real intermediate numbers. Use it when comparing mold replacement, repair, swabbing strategy, cavity wear, job length, or tooling cost recovery for bottle and jar production.

The inputs for this scenario

  • Mold sets allocated to job: 18 mold sets (unchanged)
  • Cost per mold set: 950 $ / mold set (unchanged)
  • Mold cost allocation share: 75 % (raised for this scenario; the documented default is 65)
  • Fixed mold maintenance cost: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Allocated variable mold cost = mold sets allocated to job × cost per mold set × mold cost allocation share) to the inputs above produces each figure below.
  • At this operating point the engine returns 14,625 $ for total mold life economics cost, the number this scenario is built around.
  • At this operating point the engine returns 813 $ / piece for allocated mold cost per mold set.
  • At this operating point the engine returns 12,825 $ for allocated variable mold cost.
  • At this operating point the engine returns 1,800 $ for fixed mold maintenance cost.

How this compares with the baseline

  • Against the tool's baseline example, where mold cost allocation share sits at 65% and the headline result is 12,915 $, this scenario comes in 13.24% above the baseline at 14,625 $.
  • A figure at this level is achievable when mold cost allocation share is genuinely sustained, not just peaked for a shift. It allocates cost by share rather than by measured wear; a set running near end of campaign life may justify a higher allocation than a simple percentage implies.

Results at a glance

  • Total mold life economics cost: 14,625 $ (headline result)
  • Allocated mold cost per mold set: 813 $ / piece
  • Allocated variable mold cost: 12,825 $
  • Fixed mold maintenance cost: 1,800 $
