Product launches with uncertain demand
Tooling route selection
Prototype mold vs
bridge tooling.
Choose between prototype tooling, bridge tooling and production molds based on design maturity, volume, tool life, revision risk and launch timing.

A practical sourcing route
Make the next
decision clearer.
Prototype and bridge tooling are different sourcing decisions. The right choice depends on what must be learned, how many parts are needed, whether the design will change and how the tool may transition into production.

Decision framework
Compare the
trade-offs.
| Route | Best fit | Buyer should define |
|---|---|---|
| Prototype tool | Early design and functional learning | Required samples and expected design changes |
| Bridge tool | Interim supply before production tool | Run quantity, ownership and transition timing |
| Production tool | Stable design and repeat demand | Tool life, cavitation and capability evidence |

Buyer questions
Clear answers before
you commit.
What is the difference between prototype and bridge tooling?+
Prototype tooling is usually optimized for early learning and design iteration. Bridge tooling is intended to provide interim or limited production while a longer-life production route is prepared.
Can a bridge tool become the production tool?+
Sometimes, but this depends on tool material, expected life, geometry, maintenance, cavity strategy and the production evidence required. Confirm the limit before relying on it.
How should bridge-tool ownership be documented?+
Define the owner, revision rights, tool location, maintenance responsibility, expected life, transfer conditions and what happens when the production tool is approved.
