IF IT'S MADE OF METAL
WE CAN BEND IT
Precision fabrication and machining, from your simplest run to your hardest job. If it's made of metal, we can build it — and if another shop already said no, we're worth a call.
Built for Industry.
Focused on Precision.
Since 1990, EMS has grown into a full-service fabrication and machining operation — 120,000 square feet, real capability across five service lines, and a team that's been doing this long enough to get it right the first time. Most of our work is exactly what you'd expect from a shop our size. Some of it is the job nobody else would take. Either way, we deliver.

Five Ways We Put Metal to Work

Custom Fabrication
Your one-stop shop for fabrication, big or small. We work with all metals and non-metallic materials, from kit-parts to full assemblies — and we take on the urgent or unusual jobs other shops pass on, too.

Close Tolerance Machining
From a watch pin to an aerospace component, one part or a hundred thousand, we hold the tolerance your project needs — reliably, every run.
Learn More →
Precision Laser Cutting
15-20 tons shipped every day, on equipment TRUMPF themselves have praised. The volume and precision to keep your production schedule moving.
Learn More →
Precision Forming
Reliable, repeatable forming across medical, automotive, food, energy, aerospace, and nuclear industries — including the finish-critical jobs other shops won't attempt.

Reverse Engineering, Inspection & Rapid Prototyping
From routine inspection to a part with no drawing at all, we turn physical parts into real, usable data — and document it so the next order is easy.
