Sheet metal fabrication capabilities
Eight processes, one tolerance chain. Below are the machines we run, what they hold, and how we check the result.
Processes
Eight processes, all in one building
We do not subcontract. Cut, formed, welded and finished parts still sit on the same tolerance chain when they reach the last station.
Laser cutting
Fiber laser cutting of carbon steel, stainless, aluminium and galvanised sheet from 0.5 mm to 20 mm. Nitrogen or oxygen assist depending on the edge finish you need.
CNC punching
Turret punch presses for louvers, vents, mesh panels, countersinks, extruded taps and high-volume blanks where punching beats laser on cost.
Bending & rolling
CNC press brakes up to 3200 mm and plate rolling for cylinders. Custom tooling for offset bends, hemming and closed profiles when the drawing needs it.
Welding
TIG for stainless and thin gauge, MIG for carbon steel, spot and robotic welding for repeat volume. Seam sealing for IP-rated enclosures.
Stamping & deep drawing
30-200 T presses with progressive and single-station dies for brackets, clips, contacts and drawn covers. Tooling built in-house.
Shearing & notching
Guillotine shearing up to 4000 mm for straight blanks, and notching for corner cut-outs and box folding patterns.
Surface finishing
Powder coating, liquid paint, zinc and nickel plating, anodising, bead blasting, brushing, silkscreen and laser marking.
Assembly & hardware
Press-in inserts, rivnuts, riveting, gaskets, locks, hinges, wiring harnesses and complete unit assembly with functional test.
Process limits
What each machine can hold
These are our standard working ranges. For parts outside them, tell us the requirement and we will say honestly whether it is possible.
| Process | Standard range | Repeatable accuracy |
|---|---|---|
| Fiber laser cutting | 0.5 - 20 mm, sheet up to 3000 x 1500 mm | +/- 0.1 mm |
| CNC punching | 0.5 - 6 mm, turret up to 1250 x 2500 mm | +/- 0.1 mm |
| CNC bending | 0.5 - 12 mm, length up to 3200 mm | +/- 0.2 degrees |
| Plate rolling | 1 - 12 mm, diameter from 150 mm | +/- 0.5 mm |
| Stamping | 30 - 200 T, 0.3 - 6 mm sheet | +/- 0.15 mm |
| Shearing | 0.5 - 12 mm, up to 4000 mm length | +/- 0.2 mm |
| Tapping & inserts | M2 - M12, rivnuts to M10 | +/- 0.1 mm |
| Welded assembly | Frame flatness 0.5 mm per metre | +/- 0.3 mm |
Tolerance control
Where the precision actually comes from
Tolerance is not a promise, it is a process. Four things decide whether your drawing is met: the jig, the tooling, the sequence and who checks it.
- Dedicated fixtures — Welded frames are built in jigs so the geometry is set by the fixture, not by how steady the welder's hand was that morning.
- One setup per feature — Critical holes are punched or drilled in the same setup as the datum, which removes stacking error between operations.
- Sequence discipline — Forming after welding only where required, and stress-relief or re-strike steps written into the routing, not left to the operator.
- Measured, not assumed — First-article inspection on every new part, plus sampling during the run and a final dimensional report before packing.
