Precast Mold Cycle with available precast molds or beds of 6 molds or beds: a worked example

Suppose available precast molds or beds falls to 6 molds or beds. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate good precast pieces from mold count, pieces per mold, casting cycles, and yield.

The inputs for this scenario

  • Available precast molds or beds: 6 molds or beds (the input this scenario stresses; the baseline uses 12)
  • Pieces cast per mold or bed: 4 pieces / mold (held at the documented default)
  • Casting cycles in the planning period: 2 cycles (held at the documented default)
  • Good-piece yield after stripping and inspection: 0.95 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base precast mold cycle = available precast molds or beds × pieces cast per mold or bed × cycles.
  • Precast Mold Cycle works out to 45.6 good precast pieces at these inputs, and this is the headline figure for the scenario.
  • Base precast mold cycle works out to 48 value at these inputs.
  • Good-piece yield after stripping and inspection works out to 0.95 x at these inputs.
  • Available precast molds or beds × Pieces cast per mold or bed works out to 24 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where available precast molds or beds sits at 12 molds or beds and the headline result is 91.2 good precast pieces, this scenario comes in 50% below the baseline at 45.6 good precast pieces.
  • It computes good precast pieces as molds x pieces-per-mold x casting cycles, multiplied by the good-piece yield. 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

  • Precast Mold Cycle: 45.6 good precast pieces (headline result)
