What we do

Eight services under one roof.

Every step happens in our own shop, from the first drawing through to the finished production run.

Every service in detail →

  1. Design & Testing

    From a requirement or sketch to a manufacturable design, proven with prototypes before a production run.

  2. Reverse Engineering

    Scanning and measurement turn an existing or obsolete part back into a dimensioned model you own.

  3. Fabrication

    Sheet and plate work taken from flat stock through to a finished, coated assembly.

    Welding a structural steel frame on a fabrication table

  4. Welding

    Certified TIG, MIG and stick work on structural and pressure-rated assemblies.

    Welder joining a steel panel, arc light and sparks

  5. CNC Machining

    3- and 4-axis milling and turning in aluminum, steel, stainless and exotics.

  6. Engineering Consulting

    Design, process and supplier reviews, including an honest answer when a job is better placed elsewhere.

  7. Turnkey Production

    Hand over the whole job: material, every process step, outside operations, inspection and packaging.

    Finished parts in protective netting with the job paperwork, ready to ship

  8. Manufacturing

    Repeat production from prototype quantities to mid-volume, with full process documentation.

Quality you can measure

Our Inspection Tools

Every part is checked against the print, and the results are documented and signed off.

  1. Optical Comparator

    Profile and contour inspection for complex geometries and threads.
