Why this matters
Verify DFM evidence, mold ownership terms, T1 correction process and spare-parts handoff before committing tooling spend to an overseas mold maker. A mold maker's website and sample photos say little about how they will actually handle a DFM disagreement, a T1 correction round or a dispute over mold ownership. Those three points are where an overseas tooling relationship most often breaks down, and they are all verifiable before any deposit is paid.
Buyer checks
Quote variables
| Quote variable | Why it changes the mold route |
|---|---|
| DFM review depth | A supplier who gives specific, geometry-level DFM feedback is more likely to catch problems before steel is cut than one who gives a general approval. |
| Mold ownership terms | Ownership of the physical mold and the CAD data should be settled in writing before deposit, not assumed from a verbal agreement. |
| T1 correction scope | Some suppliers include unlimited correction rounds until approval; others cap included rounds and charge for additional trials. |
| Handoff package | Spare parts, maintenance records and trial reports being included or separate changes the real total cost of the tooling relationship. |
Common mistakes
How to apply it
Request a DFM example, a written mold ownership statement and the T1 correction policy from every mold maker being compared before evaluating price, since price is only comparable once these three terms match. If the project is early, the guide can show whether the next move is CAD cleanup, DFM review, prototype tooling, production mold planning, export mold handoff or repair review.
