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.
