Platen Fit Calculator

Screen a mold footprint against machine platen dimensions, including rotation. Use this as a documented planning estimate, then validate it against the actual machine, mold, resin, and process.

Formula and method

Occupancy = larger mold-side ratio to platen x 100.

Use machine maker mounting-platen dimensions and the mold drawing’s mounting footprint.

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

A 700 x 600 mm mold on an 800 x 700 mm platen uses 87.5% of the limiting side.

What the result supports

This result is a first-pass screen for machine fit 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

Check bolt pattern, overhang rules, mold weight, and tie-bar clearance separately.
