Who we are

Built in
New Hampshire.

603 Manufacturing opened its doors in 1998. A Trexon company today, we're a diversified contract manufacturer servicing defense, aerospace, space, medical, and industrial customers.

Doctrine

The work
speaks.

We don't talk about quality. We document it. Every assembly is traceable, every conductor is tested, every revision is logged. When the unit ships, our customers know exactly what they're installing.

Our floor in Hudson runs on engineering discipline, not heroics. Production-board manufacturing. 100% continuity check. IPC-A-620 trained operators. The output is the same on a quick-turn military harness as it is on a thousand-unit medical run.

We move fast because we set up the process to move fast — not because we cut corners.
