Precast Mold Cycle with available precast molds or beds of 30 molds or beds: a worked example

What does the result look like when available precast molds or beds reaches 30 molds or beds? The full calculation is worked below with real intermediate numbers. a precast plant needs to estimate pieces available from molds or casting beds over a shift or day

The inputs for this scenario

  • Available precast molds or beds: 30 molds or beds (raised for this scenario; the documented default is 12)
  • Pieces cast per mold or bed: 4 pieces / mold (unchanged)
  • Casting cycles in the planning period: 2 cycles (unchanged)
  • Good-piece yield after stripping and inspection: 0.95 x (unchanged)

Working through the calculation

  • Applying the documented formula (Base precast mold cycle = available precast molds or beds × pieces cast per mold or bed × cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 228 good precast pieces for precast mold cycle, the number this scenario is built around.
  • At this operating point the engine returns 240 value for base precast mold cycle.
  • At this operating point the engine returns 0.95 x for good-piece yield after stripping and inspection.
  • At this operating point the engine returns 120 value for available precast molds or beds × pieces cast per mold or bed.

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 150% above the baseline at 228 good precast pieces.
  • A figure at this level is achievable when available precast molds or beds is genuinely sustained, not just peaked for a shift. It assumes a single representative product and uniform yield; it does not model mold changeover time, cure-time constraints, mixed product runs, or curing capacity bottlenecks.

Results at a glance

  • Precast Mold Cycle: 228 good precast pieces (headline result)
  • Base precast mold cycle: 240 value
  • Good-piece yield after stripping and inspection: 0.95 x
  • Available precast molds or beds × Pieces cast per mold or bed: 120 value
