Trustbridge | Injection Molding & Product Design Experts

Trustbridge offers end-to-end plastic injection molding services through a global network of certified molders. From rapid prototyping to high-volume production, we connect your project to the best-fit partner based on mold complexity, part geometry, material requirements, and certifications.

Whether you're launching a new consumer product or producing mission-critical medical or automotive components, Trustbridge combines intelligent supplier matching with in-house engineering support to ensure quality, consistency, and speed — from first shot to full production.

What Tolerances Can You Expect?

Plastic injection molding is ideal for precision and repeatability at scale. Our network delivers:

Standard Tolerances: ±0.005 in (±0.13 mm)
Tight Tolerances: ±0.001–0.002 in (±0.025–0.05 mm) for critical dimensions
Surface Finish: From molded-in textures to polished, SPI-A2 mirror finishes
Post-Processing: Assembly, ultrasonic welding, pad printing, painting, chrome plating, and more

Our engineers review every part for DFM and tolerance feasibility before mold kickoff.

What’s the typical lead time for tooling and production?

Rapid Tooling: 1-2 Weeks
Production Tooling (Steel)tion Tooling (Steel): 3-6 Weeks

Production Runs: 3-10 business days after T1 approval

Do you offer part design or DFM review?

Yes — our engineers provide complimentary design-for-manufacturing (DFM) feedback with every quote.

Can I start with low volumes and scale later?

Absolutely. We support pilot runs, bridge tooling, and scalable production plans.

Can you produce and assemble multi-part products?

Yes — many of our suppliers offer assembly, packaging, and fulfillment options.

What’s the minimum order quantity?

We accommodate low volumes — even <100 parts — with aluminum tools, and scale to millions of units.
