Wax / resin to metal
Convert pattern weight into estimated casting metal weight using material density, buffer, and shrinkage assumptions.
A casting calculator built around the quote, not just the formula.
Most casting estimates still live in scratch notes, spreadsheets, or mental math. Metal Casting Cost Calc keeps the assumptions visible so you can explain the number later.
Cost before you commit
Use delayed market data or your own supplier price per gram, then add premium and margin for quote prep.
Saved quote snapshots
Save the exact cost assumptions used for a job, including source, timestamp, premium, and margin.
From pattern to quote in under a minute.
1
Enter pattern
Use wax/resin weight or a rough box estimate when you only need a quick planning number.
2
Choose metal
Select from jewelry and workshop metals/alloys with sensible density presets.
3
Set assumptions
Adjust shrinkage, sprue/button buffer, supplier premium, and margin close to the result.
4
Save quote
Keep a job snapshot so the estimate remains explainable when prices or assumptions change.
Who it is for
A focused utility for workshop decisions, early quote prep, and metal buying estimates.
Jewelry studios estimating sterling, gold, bronze, brass, and other castings.
Small foundries preparing rough material quotes before ordering or melting metal.
Lost-wax and resin casting workflows where pattern weight is the fastest starting point.
Makers who want saved assumptions instead of one-off calculator results.
Honest limitations
Metal Casting Cost Calc is a quote-prep and planning tool. It is not an engineering certification tool, safety procedure, supplier invoice, or substitute for qualified foundry practice. Rough dimension mode is an approximation; measured pattern weight is the preferred workflow.
Launch plan: free first, feedback-driven next.
The first App Store version is planned as free so real foundry and jewelry users can test the workflow. If the app earns retention, future Pro features may focus on templates, exports, supplier libraries, and advanced geometry — without weakening the core quick quote flow.
FAQ
Is Metal Casting Cost Calc free?
The launch version is planned as free to collect feedback from real workshop users.
Does it collect personal data?
No account is required. Saved calculations and quote snapshots are stored locally on your device in this release.
Can I use my own supplier prices?
Yes. The app supports pricing overrides and supplier premium assumptions for quote prep.
Is rough dimension mode CAD-accurate?
No. Rough dimension mode is a convenience approximation. Measured wax or resin pattern weight is the preferred, higher-value workflow.
