Machining · ±0.005 mm

CNC machining

Our CNC machining centres and lathes run three shifts, five days a week. Lights-out cells with pallet changers keep repeat parts moving...

Machining · complex geometry

5-axis machining

Simultaneous 5-axis machining lets us reach every face of a complex part in one setup. Fewer setups mean better feature-to-feature accuracy and...

Fabrication · laser & bending

Sheet metal fabrication

From flat laser-cut blanks to fully formed enclosures, our sheet metal line handles prototypes and production on the same equipment, so nothing...

Fabrication · MIG, TIG & robotic

Welding & fabrication

Certified welders and robotic cells produce frames, skids and structural weldments to qualified procedures, with fixtures designed in-house for repeatable accuracy. How...

Finishing · in-house

Finishing & coating

Keeping finishing in-house removes the most common cause of late deliveries: waiting on outside processors. Every finish is checked for thickness and...

Assembly · ready to install

Assembly & kitting

We assemble machined and fabricated parts with bought-in components, test them and deliver kits to your line, so your team builds products...

From CAD to delivery

Four steps from drawing to dock.

The same clear path for a single prototype or a five-year production contract.

  1. Send your CAD

    Upload STEP, IGES or PDF drawings with quantities, material and finish. NDAs signed on request.

  2. Quote & DFM review

    A costed quote within 24 hours, with design notes that can lower your price.

  3. First article & production

    We prove the process on a first article, then run your batch on scheduled capacity.

  4. Inspected & shipped

    Every lot is inspected to drawing and shipped with reports and material certificates.

Quality you can measure

Measured, recorded and signed off.

Our climate-controlled quality lab checks parts against your drawing on coordinate measuring machines, optical comparators and surface testers. Every critical feature is recorded, and the report ships with your parts.

  • First article inspection on every new part number
  • Statistical process control on production runs
  • Full material traceability, lot by lot

What engineers say

A supplier you stop worrying about.

Northfield's DFM notes took 30% out of our housing cost before a single chip was cut. Two years in, we have not had one late delivery.

Dana R.Supply chain lead, Arcline Robotics

First articles arrive with a full CMM report and the production parts match them every time. That consistency is rare.

Miguel S.Quality manager, Veritas Surgical

We moved three assemblies from overseas to Northfield and cut our lead time from 14 weeks to 3. The project engineer is an extension of our team.

Priya K.Director of operations, Halden Energy Systems
