OEE Capacity Calculator

Estimate good-part capacity using availability, performance, quality, cycle, and cavities. Use this as a documented planning estimate, then validate it against the actual machine, mold, resin, and process.

Formula and method

Good output = ideal cycles x availability x performance x quality x cavities.

Use clearly defined OEE factors from the same time window and an agreed ideal cycle.

Inputs and units

Use controlled records, CAD, measured production data, the exact resin data sheet, or machine-maker specifications. Keep the material and time basis with the result.

Worked example

480 min, 30 s, four cavities, 85% availability, 95% performance, 97% quality = 3,165 parts.

What the result supports

This result is a first-pass screen for production planning. Use it to identify the next record or engineering check, not as a release decision.

Sanity check

Check the unit basis and whether all quantities describe the same cavity, shot, machine, or production window before comparing values.

Important limitation

OEE definitions vary by site; retain the loss-accounting rule with the result.
