Plastic Injection Molding Services for Custom Parts

SANGO takes your part from a handful of prototype units to full production runs on the same tooling philosophy, with T1 samples ready in as fast as 2 weeks. Our China-based facilities run 90 to 830-ton presses, so small precision components and large structural housings both stay in-house.

Precision mold tooling, overmolding, and insert molding all run through the same DFM review before steel is cut, so bond compatibility and wall thickness are checked once rather than per process. One partner across design, tooling, and production means fewer handoffs, tighter part consistency, and a clearer path to scaling volume.

Applications of Injection Molding

Injection molding is huge in making a ton of products—anything from car parts to medical devices. It’s super efficient because it can produce lots of identical plastic parts with tight tolerances, all at a low cost per part. That’s why so many industries rely on it for mass production. Whether it’s a simple or complex design, it keeps quality high and production fast.
