Mold Life Economics at 47% mold cost allocation share: a worked example

This worked example runs the mold life economics numbers for a tougher week than the baseline: 47% mold cost allocation share instead of the typical 65%. Estimate mold-life economics for glass container jobs by combining mold equipment count, cost per mold set, allocation share, and fixed maintenance or qualification cost.

The inputs for this scenario

  • Mold sets allocated to job: 18 mold sets (held at the documented default)
  • Cost per mold set: 950 $ / mold set (held at the documented default)
  • Mold cost allocation share: 47 % (the input this scenario stresses; the baseline uses 65)
  • Fixed mold maintenance cost: 1,800 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Allocated variable mold cost = mold sets allocated to job × cost per mold set × mold cost allocation share.
  • Total mold life economics cost works out to 9,837 $ at these inputs, and this is the headline figure for the scenario.
  • Allocated mold cost per mold set works out to 547 $ / piece at these inputs.
  • Allocated variable mold cost works out to 8,037 $ at these inputs.
  • Fixed mold maintenance cost works out to 1,800 $ at these inputs.

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 23.83% below the baseline at 9,837 $.
  • Use it when quoting a new container, costing a campaign, or deciding whether to retire or refurbish an aging mold set. 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

  • Total mold life economics cost: 9,837 $ (headline result)
  • Allocated mold cost per mold set: 547 $ / piece
  • Allocated variable mold cost: 8,037 $
  • Fixed mold maintenance cost: 1,800 $
