How do I calculate mold wear cost per piece?

Divide mold purchase, repair, or refurbishment cost by the expected acceptable pieces the mold will produce before replacement.

Can this be used for press dies?

Yes. Use die wear cost per pressed piece and fixed setup or refurbishment cost for the tile size or press mold set.

What if mold life varies by product?

Run separate estimates for each fixture shape, tile size, body recipe, or casting method because mold life can vary significantly.

What decision does this support?

Use it to compare plaster versus resin molds, justify refurbishment, set replacement timing, or include mold wear in product costing.

Mold Life Cost Calculator

Mold Life Cost helps sanitaryware producers, tile plants, and procurement teams understand how mold wear affects cost per piece. It is useful for plaster molds, resin molds, pressure casting molds, press dies, and mold sets used for toilets, basins, sinks, tiles, and shower trays.

What this calculator does

Estimate the mold cost assigned to slip-cast or pressed ceramic pieces based on mold life, piece volume, and fixed maintenance cost.
a casting, pressing, or procurement team is estimating mold wear cost for a product family or production run
The result estimates mold wear and fixed mold support cost assigned to a ceramic production scope.

Formula used

Allocated mold wear cost = pieces produced on the mold set × mold wear cost per piece × product allocation
Total mold life cost = allocated mold wear cost + fixed mold setup or refurbishment cost

Inputs explained

Pieces produced on the mold set: Count the cast fixtures, pressed tiles, or formed pieces expected from the mold, die, or mold set over the costing period.
Mold wear cost per produced piece: Use mold purchase or refurbishment cost divided by expected mold life in acceptable pieces.
Mold cost allocated to this product: Use the share assigned to the size, shape, customer order, product family, or production campaign.
Fixed mold setup or refurbishment cost: Add mold conditioning, repair, storage, setup, changeover, inspection, or refurbishment cost not captured per piece.

How to use the result

Use it when quoting sanitaryware, comparing mold materials, setting mold replacement plans, or reviewing cost per fixture.
It depends on expected mold life and does not predict defects from mold wear, dimensional drift, or casting-rate loss unless those costs are included.
