Between the last prototype and full mass production there is often a gap of weeks or months while molds and dies are built. Bridge production fills that gap with low-volume manufacturing so you can ship to first customers, run field tests and validate demand.
Why Bridge Production Matters
- Start revenue earlier instead of waiting for tooling
- Collect real-world feedback before freezing the design
- Reduce risk if tooling is delayed
- Test the market with a few hundred units
Processes Used for Bridge Production
| Final process | Bridge process |
|---|---|
| Die casting | CNC machining from billet |
| Stamping | Laser cutting + CNC bending |
| Injection molding (steel mold) | CNC machined plastic or aluminum prototype mold |
| Forging | CNC machining from bar |
Planning Checklist
- Freeze critical interfaces even if cosmetic details may change.
- Agree on inspection points for every batch.
- Choose finishes that match production as closely as possible.
- Plan quantities per batch to balance setup cost and cash flow.
- Keep revision control — every batch should reference a drawing revision.
Cost Expectations
Bridge parts cost more per unit than mass-production parts but avoid the tooling investment and waiting time. For many products, the earlier revenue more than offsets the higher unit cost.
One Supplier, Fewer Handovers
Using the same supplier from prototype through bridge production keeps programs, fixtures and quality records consistent. That is the model we follow for OEM metal parts and low volume CNC machining.

FAQ
What is bridge production?
Low-volume manufacturing used between prototyping and mass production, typically while production tooling is being made.
How many parts are made in bridge production?
From dozens to a few thousand, depending on demand and tooling lead time.
Is bridge production more expensive?
Unit cost is higher, but no tooling is required and you can sell sooner.
