Bridge Tooling


Visit Website

Your design has been approved, and production tooling has been ordered. But right now you need 200 to 20,000 injection-molded parts as quickly as possible. Bridge tooling helps you bridge this gap between prototyping and high volume production.

Short Run Production Injection Modeling


Visit Website

Once your design has been prototyped and tested, InterPRO can deliver low to medium-volume injection molded parts in ABS, Polycarbonate, Nylon, Polypropylene and almost any other thermoplastic material using bridge (prototype) tooling. Our injection molding team has decades of experience in mold design, mold build and production. Depending on the needs of your project, we can build your mold using either aluminum or steel.

We will help you determine which prototyping and production process will be right for your project, and help you optimize your design for molding and product performance. Our process allows mold construction using hand pick-outs and automated cam actions. Part geometry, regardless of complexity is not a problem.

InterPRO has recently added 1200 square feet of manufacturing space dedicated to injection molding. In addition to our in-house team, we have a strong network of American mold designers and mold builders who compliment our capabilities.

We now offer 9 SLA systems in house!
We just installed two high resolution SLA Viper systems, and two large frame SLA systems.

Viper quality parts are the industry standard for high resolution, excellent detail and accuracy. With a total of four large frame SLA systems, we are providing much faster delivery... especially on very large parts.

We have also added six more SLA resins, giving you a wider selection of material properties to choose from.

With this increase in our SLA production capabilities, we can now ship your order in as little as 24 hours.
