Niagara Manufacturing
A precision machine shop in northwestern Pennsylvania. We've been cutting metal for demanding industries since the beginning — and we're still at it.
Built on the Shop Floor.
Niagara Manufacturing was founded in northwestern Pennsylvania with one goal: machine parts right the first time. No shortcuts, no excuses. We built the shop around the kind of work that doesn't leave room for error — oil and gas components, heavy equipment parts, pressure-rated fittings that go into the field and stay there.
Over the years we've grown the floor, added equipment, and brought in the people who know how to run it. But the core hasn't changed. We still read every print carefully, ask the right questions before we cut, and inspect every job before it ships.
Our customers come back because we hold tolerances, hit lead times, and don't make them chase us down for answers. That's the standard we hold ourselves to — every job, every time.
Our Facility
Our shop floor runs modern CNC turning centers, milling machines, grinding equipment, and a full inspection department with CMM capability. We've invested in the equipment and the people to handle complex, tight-tolerance work for oil & gas and heavy equipment customers.
What We Stand For.
Accuracy First
We machine to your print tolerances — not close enough. If something is unclear, we ask before we cut.
Full Traceability
Material certifications, heat numbers, and inspection reports ship with every job. No guesswork on what went into your part.
Straight Talk
We quote honestly, communicate lead times clearly, and tell you early if something changes. No runaround.
Long-Term Relationships
Most of our customers have been with us for years. We earn that by performing consistently, not just on the first job.
Let's Work Together.
