How do you calculate mold life cost?

Multiply pieces produced by the wear cost per piece and your product allocation percentage to get allocated wear cost, then add fixed setup or refurbishment cost. With 8,500 pieces at $0.32 each, fully allocated, plus $1,800 fixed, total mold life cost is $4,520.

What is mold cost per produced piece?

It is total mold life cost divided by the number of pieces the mold set makes. In the worked example, $4,520 over 8,500 pieces is about $0.53 per piece, which is the tooling rate you should bake into the quote.

Why allocate only a percentage of mold cost to a product?

A single mold set may run several body types or glazes. The allocation percentage assigns the share of wear caused by this specific product. At 100% the product carries the full wear; at 50% it would split the $2,720 allocated wear cost with another SKU.

What is a good mold life for sanitaryware casting?

Traditional plaster molds for sanitaryware typically yield 80-150 casts, while high-pressure resin molds run 20,000-40,000 cycles. A higher piece count spreads the fixed refurbishment cost thinner, lowering cost per piece.

Should refurbishment cost go in fixed cost or wear cost?

One-time costs like resurfacing, re-cutting parting lines, or a new master should sit in the fixed setup or refurbishment field. Per-cycle abrasion and absorbency loss belong in the wear cost per piece.

How can I lower mold cost per piece?

Extend usable mold life by controlling slip pH and casting pressure, run more pieces before refurbishment, and increase the allocation accuracy so each product carries only its real share of the $2,720 wear cost.

Ceramic, Tile & Sanitaryware Manufacturing calculator

Mold Life Cost Calculator

Mold Life Cost spreads the wear and refurbishment expense of a plaster, resin, or pressure-casting mold across the pieces it produces before it is scrapped. Process engineers and cost estimators in tile and sanitaryware plants use it to set realistic per-piece tooling rates instead of treating molds as free. Because high-pressure casting and slip-casting molds degrade with every cycle — losing edge definition and absorbency — knowing the true mold cost per piece protects margins on long runs and exposes products whose short mold life makes them unprofitable.

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
It computes the total cost a mold set carries over its life by combining per-piece wear cost across the run with fixed setup or refurbishment cost, then divides by output for a cost per piece.

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:
Mold wear cost per produced piece:
Mold cost allocated to this product:
Fixed mold setup or refurbishment cost:

How to use the result

Use it when quoting a new SKU, comparing plaster versus resin tooling, or deciding whether a worn mold is worth refurbishing or replacing.
It assumes a constant wear cost per piece, but real molds degrade non-linearly — defect rates climb sharply near end-of-life, so the last few hundred pieces may cost far more than the average implies.
