Required Cavity Count and Capacity Planner

Estimate the minimum active cavities needed to meet an order within the available production window.

Example starting values are prefilled to demonstrate the calculation. Replace them with your measured, quoted, or job-specific inputs before relying on a result.

Inputs

Order, time, and process assumptions

Range: at least 1 parts

Integer order quantity of accepted parts.

Range: at least 0.0 h

Total scheduled time available for this order, before applying planned runtime utilization.

Range: at least 0.0 s/cycle

Measured full cycle with overlapping machine-clock phases counted once.

Range: 0.0–100 %

Expected share of scheduled hours available for cycling after downtime/setups. Do not also remove this time from available hours.

Range: 0.0–100 %

Accepted parts divided by attempted parts. Keep separate from runtime utilization; startup loss must be included in the yield assumption or scheduled time.

Result

Scheduled molding cycles available (cycles)
16,320
Expected good-part output (parts)
111,955.2
Good-part capacity headroom (parts)
11,955.2
Minimum theoretical active cavities (cavities)
7
Meets target under entered assumptions
Planning assumptions
Planning scenario only. Available cycles = floor(scheduled hours × runtime utilization × 3,600 / cycle time). Expected output applies good yield once and assumes the same active cavities operate for every available cycle. Setup shots, cavity-specific losses, mold feasibility, and press capacity are not modeled.
