Processes
From flat blank to finished, assembled part
Laser cutting & punching
Fibre laser cutting and CNC punching of flat blanks, holes, slots and cut-outs.
CNC bending & forming
Press-brake bending for brackets, channels, boxes and enclosures with multiple bends.
Welding & hardware
TIG / MIG and spot welding, press-in nuts, studs and standoffs, rivets and simple assembly.
Coating & finishing
Powder coating (RAL colours), zinc plating, anodizing, brushing and silk-screen printing.
Typical capabilities
What our sheet metal partners typically handle
Typical ranges across our partner shops, not guarantees. The achievable result for your part is confirmed in the quote after we review your drawing.
Sheet metal parts can be bulky. We'll suggest packing and shipping options (e.g. combining with your CNC parts, or sea freight for larger batches) to keep freight cost sensible.
| Quantities | Prototypes from 1 piece; small and medium batches depending on the part. |
|---|---|
| Materials | Cold-rolled steel (DC01 / SPCC), galvanised steel (DX51D / SECC), stainless steel 304 / 316, aluminium 5052 / 6061, copper and brass on request. |
| Thickness | Typically around 0.5–6 mm, depending on material and process. Thicker plate on request. |
| General tolerance | ISO 2768-m unless your drawing specifies otherwise. |
| Typical tolerances | Laser-cut features commonly around ±0.1–0.2 mm; formed (bent) dimensions are looser — commonly around ±0.3–0.5 mm and about ±1° on bend angles. Depends on partner factory, material and part size. |
| Joining & hardware | TIG / MIG / spot welding; PEM-style press-in fasteners; rivets; simple sub-assembly. |
| Finishes | Powder coating, wet painting, zinc plating, anodizing (aluminium), brushing, passivation, silk-screen and laser marking. |
| Lead time | Depends on bends, welding, finish and quantity. As a rough guide, simple samples often take about 1–2 weeks and small batches about 2–4 weeks, plus shipping. Confirmed in each quote. |
| Files | 3D model (STEP) plus PDF drawing preferred; DXF/DWG flat patterns welcome. |

Design tips
Make sheet metal parts easier — and cheaper — to quote
- State material, thickness and grade on the drawing
- Keep one inside bend radius where possible
- Tighten tolerances only where parts mate
- Specify hardware part numbers (e.g. press-in nuts)
- Give RAL colour, gloss level and masked areas for coating
- Mark cosmetic (visible) sides and weld finish requirements
