Bringing a [medical device component](https://www.extrememolding.com/healthcare-products) from initial design to full-scale production involves several important decisions. One of the biggest is determining when to invest in production tooling, especially when parts are still undergoing testing and validation.

For companies developing silicone medical components, investing in high-volume tooling too early can create unnecessary costs and limit flexibility. However, relying on prototyping methods for too long can delay development and make it difficult to produce the quantities needed for testing.

This is where bridge tooling comes in.

In this article, we'll explain what bridge tooling is, when it makes sense, and how it supports the transition from prototype development to medical component manufacturing.

## What Is Bridge Tooling?

Bridge tooling is a manufacturing approach that fills the gap between initial prototyping and full-scale production. It involves creating a mold capable of producing larger quantities of parts without the upfront investment associated with fully automated production tooling.

Unlike prototype molds, which are generally designed to produce smaller quantities for early evaluation, bridge tools are built to support more extensive testing and intermediate production requirements.

In silicone manufacturing, bridge tooling may use a simplified mold design with fewer cavities than a high-volume production mold. This allows manufacturers to produce functional components using the intended silicone material and an appropriate molding process while keeping tooling costs more manageable.

Depending on the application, bridge tooling can support production quantities ranging from approximately 10,000 to 150,000 parts.

For medical device manufacturers, bridge tooling can be particularly valuable for producing the quantities of silicone components needed for verification and validation (V&V) testing.

 

## When Is Bridge Tooling Used in Manufacturing?

Bridge tooling is typically introduced when a product has progressed beyond initial prototyping but isn't ready for full-scale manufacturing.

In [medical part manufacturing](https://www.extrememolding.com/healthcare-products), development timelines, testing requirements, and production volumes don't always align. Bridge tooling helps companies address these needs while finalizing their long-term manufacturing strategy.

Some common situations where bridge tooling makes sense include:

 

- Verification and validation testing: Producing sufficient quantities of medical components to evaluate performance, functionality, and consistency.
- Design refinement: Allowing manufacturers to evaluate molded components and identify potential improvements before investing in more expensive production tooling.
- Limited production runs: Supporting smaller manufacturing quantities when demand doesn't yet justify fully automated tooling.
- Production transitions: Maintaining access to molded components while long-term production molds are being developed or qualified.
- Managing upfront costs: Spreading tooling investments across different development stages rather than committing to the full cost of high-volume manufacturing immediately.

For example, a medical device manufacturer may begin with compression molding to produce a few hundred samples for initial evaluation. As development progresses, bridge tooling can provide thousands of additional silicone components for testing and validation without requiring an immediate investment in fully automated production tooling.

While bridge tooling isn't necessary for every project, it can provide a practical solution when manufacturing requirements extend beyond what traditional prototyping can support.

## What Are the Benefits of Bridge Tooling?

For companies developing silicone medical components, bridge tooling offers several advantages that can help streamline the manufacturing process.

### Lower Upfront Tooling Costs

One of the primary benefits of bridge tooling is the ability to produce larger quantities of parts without immediately investing in fully automated production molds.

At Extreme Molding, bridge tooling can typically cost approximately 20–30% of a fully automated mold, depending on the project's requirements.

This allows companies to allocate resources toward testing, validation, and other development priorities while preparing for future production.

### Greater Flexibility During Development

Medical device components often require extensive evaluation before their designs are finalized. Bridge tooling provides an opportunity to assess how components perform under intended conditions and make necessary adjustments before transitioning to more complex production molds.

Although modifications may still involve additional tooling costs, this approach gives development teams an opportunity to refine components before committing to final production tooling.

### Support for Testing and Validation

Medical component manufacturing requires careful attention to material selection, dimensional accuracy, and product performance. Bridge tooling allows manufacturers to produce larger quantities of molded parts for verification and validation activities, helping development teams evaluate whether components meet their intended specifications.

When appropriately designed, bridge tools can also support testing with the same silicone material intended for future production.

However, any testing or validation requirements must account for differences between bridge tooling and the final production process.

### Reduced Manufacturing Risk

Investing in [high-volume production](https://www.extrememolding.com/blog/factors-to-consider-when-upscaling-production-to-large-volumes) tooling before a component has completed the necessary testing can introduce financial and operational risks.

Bridge tooling helps manufacturers take a more measured approach by allowing them to evaluate components and address potential manufacturing challenges before making a larger investment.

This can help reduce the likelihood of costly tooling modifications and unexpected production delays.

### A More Manageable Transition to Full-Scale Production

Rather than moving directly from a small prototype run to a fully automated manufacturing process, companies can use bridge tooling to gradually increase production capacity based on their development milestones.

This staged approach helps support a more predictable transition to full-scale manufacturing.

## Bridge Tooling vs. Production Tooling: What's the Difference?

Bridge tooling and production tooling serve different purposes during product development. While bridge tooling supports testing, validation, and intermediate production, production tooling is designed for long-term, high-volume manufacturing.

Here's how the two approaches compare:

| **Feature** | **Bridge Tooling** | **Production Tooling** |
| --- | --- | --- |
| Primary purpose | Testing, validation, and intermediate production | Long-term, high-volume manufacturing |
| Production volume | Approximately 10,000-150,000 parts, depending on application | Hundreds of thousands to millions of parts |
| Initial investment | Generally lower | Generally higher |
| Mold design | Often simplified, with fewer cavities | May use multi-cavity, fully automated tooling |
| Design flexibility | Can accommodate refinements, depending on tool design | Changes may be more complex and costly |
| Best suited for | Products undergoing testing or transitioning to production | Established products with sustained production demand |

For silicone medical components, fully automated cold deck tooling is one option for high-volume production. This approach helps reduce material waste and supports efficient, repeatable manufacturing.

Ultimately, choosing between bridge and production tooling depends on the component's design, required quantities, development timeline, and long-term manufacturing goals.

## How Extreme Molding Plans Your Tooling Path

At Extreme Molding, we understand that every medical component manufacturing project comes with its own requirements, timelines, and production goals.

Rather than taking a one-size-fits-all approach, our team works with customers to identify the manufacturing methods that make the most sense at each stage of product development.

In some cases, this means starting with compression molding for initial prototypes, transitioning to bridge tooling for testing and validation, and eventually moving to fully automated silicone injection molding.

One recent[medical device manufacturing project](https://www.extrememolding.com/blog/medical-device-manufacturing-case-study) demonstrates how this approach works in practice. The customer required molded silicone samples within just three weeks, followed by thousands of additional parts for verification and validation testing. At the same time, the manufacturing strategy needed to accommodate projected annual demand of five million components.

By planning each stage around the project's immediate and future requirements, our team helped the customer meet critical development milestones while managing tooling investments.

Whether you're developing a new medical device component or preparing to scale an existing design, our team can help determine the right tooling strategy for your project.
