Capabilities

Six capabilities, one factory, one point of contact

Most suppliers do one of these and broker out the rest. We run them on our own floor, which is why a part can move from raw material to packed box without leaving our control.

01

CNC Machining & Turning

Turned and milled components in stainless, carbon steel, brass and aluminium — nozzles, bushings, shafts, flanges, pulleys, spacers and stepped parts, produced to your drawing.

  • Precision turning
  • CNC machining

02

Stamping & Deep Drawing

Stamped and deep-drawn parts on our own press line: brackets, latches, hardware, enclosures, trays, pans and drawn stainless vessels.

  • Stamped parts
  • Deep drawing
  • Formed parts

03

Forging

Forged blanks and near-net shapes for components that have to carry load, finished on our own machining lines rather than shipped out raw.

  • Forged blanks

  • Ductile iron

05

How we work

From your drawing to a packed pallet

The same five steps run on every order, whether it is a sampling batch or a repeat production run.

STEP 01

Drawing & inquiry

Send a 2D/3D drawing, a specification or simply a sample. We check material, tolerance and finish, come back with any questions and quote within 24 hours.

STEP 02

Tooling & mold design

Molds, dies and fixtures are designed and built in-house, which keeps tooling cost, revisions and lead time under our own control.

STEP 03

Sampling & approval

First articles are produced, measured and sent to you for approval. Nothing moves to mass production until the sample is signed off.

STEP 04

Production & inspection

Casting, machining, stamping and welding run on our own floor, with inspection at every handover between processes.

STEP 05

Finishing, assembly & export

Polishing, surface treatment, sub-assembly, export packing and documentation — the part leaves the factory ready to use.
