Casting shells, mould cavities and mixed-material packages.
Measure outer cast geometry and the actual inner cavity, submerged master displacement or supplied recess. Subtract one whole cavity rather than adding overlapping wall volumes.
Gather the selected product data
Enter prepared mixed volume yield per selected kit or bag. Dry package mass and the outside dimensions of a box are not substitutes for mixed yield.

Rectangular Mould Box Master Displacement Kit Calculator
Subtract supplied master displacement from a measured rectangular mould box before ordering mixed material kits.
Tapered Round Pot Casting Shell Material Calculator
Subtract a supplied tapered inner cavity from the outer pot, checking that the cavity fits at the supplied base height.
Rectangular Planter Casting Shell Material Calculator
Count supplied rectangular shell volume without double-counting the corners where side walls meet.
Round Cast Disk Face Recess Material Calculator
Subtract a supplied centred circular face recess from a cast disk and convert retained volume to mixed material packages.
Hemispherical Bowl Casting Shell Material Calculator
Measure a supplied hollow hemispherical shell by subtracting the inner hemisphere, retaining its closed lower shell.
Flat Annular Sector Casting Material Calculator
Measure a flat ring-sector casting from supplied inner and outer diameters, sweep angle and thickness.

How to measure and order: casting shells, mould cavities and mixed-material packages
Which measurements and product data prevent quantity mistakes for this job?
Small versus large mixed-yield packages for the same shell: quantity checks
The same shell needs different package counts when supplied mixed yields differ. The count does not establish a suitable casting compound or a cheaper order.

Keep the estimate within scope
All shell geometry and product yield are supplied. The tools do not choose wall thickness, reinforcement, strength, curing, chemical mix ratios, food contact or safe handling. Recesses and inner cavities must remain inside the supplied outer shape.
