Capabilities

Raw steel in one door, finished part out the other

Cutting, forming, welding, moulding, rubber and coating all happen on our own floor. Nothing is farmed out to a subcontractor you cannot see, which is why our lead times hold and our quality does not drift between runs.

Machining line
01 — Metal forming

Cutting, stamping and bending

Laser & sheet cutting

Sheet and tube cut to profile with clean edges that carry straight into welding without secondary work.

  • Mild steel, stainless, aluminium
  • Tube and section cutting
  • Nesting for material yield

Stamping & punching

Progressive stamping on dies cut in our own tool room — so a die correction is a walk across the floor, not a shipment.

  • Rim halves and hub components
  • Brackets, plates, perforated panels
  • Tooling stored on site for repeat runs

Automated bending

Brake press and tube bending held to repeatable angles across a full production run.

  • Handles, frames, legs
  • Multi-bend fixtures
  • First-article check before run
02 — Assembly & finishing

Welded, coated and boxed in-house

Jigged MIG and spot welding, then straight onto our own powder coating line. Because coating is ours, colour matching and film thickness are controlled instead of negotiated.

Welding

Fixtured MIG and spot welding for frames, brackets and full assemblies, with weld checks built into the line.

Powder coating

Pretreat, coat and cure on our own line. Your RAL or Pantone, consistent from first carton to last.

Assembly & packing

Bearings pressed, wheels fitted, retail packaging and barcodes applied to your artwork.

Assembly and inspection
03 — Rubber & moulding

We make the tire, not just the wheel

Rubber

Mixing & curing

Our own compound, our own cording structure, vulcanized and cured on site — the reason our tires hold tread life claims.

Polyurethane

Low-pressure PU injection

Flat-free tires foamed onto our standard rims, so a customer can switch from air without changing the fork.

Plastics

Plastic injection

Rims, hubs, trays and moulded components matched to the steelwork in the same assembly.

04 — Tooling & engineering

Your tooling, built and kept here

We cut dies and build fixtures in our own tool room. When you invest in tooling with us, it stays on our floor for your runs only — never listed on our sites, never taken to a trade show.

Drawing or sample

Send a CAD file, a PDF drawing, or the physical part. We reverse-engineer from a sample when no drawing exists.

Honest tooling call

We tell you plainly whether new tooling is needed or an existing die can be modified.

Prototype first

A physical prototype for your approval before a production run is scheduled.

NDA on request

Signed before you send anything, if that is how you prefer to work.

05 — Quality & logistics

Checked before it leaves, shipped how you buy

In-line inspection

Dimensional and weld checks at each station, not only at the end of the line.

Pre-shipment sampling

AQL sampling before container loading. Third-party inspection welcome.

Two countries

Thailand and China factories let us quote the better landed cost and route around tariffs.

FCL & LCL

Work with your freight forwarder, or we ship direct to your door.
