Hardware we produce
Typical parts we manufacture for electronics programs
| Part type | Why we make it this way | Material families |
|---|---|---|
| Heat sinks and cold plates | Extruded aluminium profiles cut and finish-machined, with secondary CNC for mounting features | 6063, 6061, 1100 aluminium, copper for high-load |

| RF shielding cans and covers | Tight tolerance sheet metal parts with conductive plating or tin finish | Copper, brass, tin-plated steel |
| ICT and flying probe test fixtures | Machined plates with integrated locating features for repeatable test contact | Phenolic board backing, anodized aluminium frames |
| Connector shells and backshells | CNC turned and milled precision connector bodies with controlled plating | Brass, copper, stainless, engineering plastics |
| Plastic enclosures and bezels | Production-volume injection molding with machined polymer for prototype | ABS, PC, PC/ABS, PBT |
| Busbars and power distribution | Machined copper and aluminium with insulation and plating options | C110 copper, 6061, tin plating |
Manufacturing route we recommend
- Sheet metal fabrication for equipment enclosures, RF shields and mounting plates.
- Aluminum extrusion for heat sinks, chassis rails and thermally loaded structural profiles.
- CNC milling and turning for connectors, test fixtures and small precision components.
- Injection molding for production-volume enclosures, bezels and insulator parts.
- Precision turning for connector bodies, threaded standoffs and turned electronic hardware.
- Dimensional inspection for RF shield fit and ICT fixture accuracy, with first article on every new fixture.

- Selective masking for partial plating or anodizing
Recent project snapshot
Power-converter chassis — extrusion plus sheet metal sub-assembly
A power-converter chassis was built from an extruded 6063 heat-sink base and a formed 5052 enclosure, with machined corner brackets and a powder-coated finish. The whole sub-assembly was dimensionally inspected against a master fixture and shipped on a four-week Kanban to the system integrator.
- Process
- Aluminium extrusion + sheet metal + precision machining
- Tolerance
- ±0.05 mm on mounting surfaces, 0.1 mm flatness on heat-sink base
- Documentation
- First article, material certs, surface treatment certs
- Outcome
- 5 000 chassis shipped annually with consistent thermal performance
Frequently asked questions
Can you produce custom heat-sink profiles?
Yes. We work with extrusion partners on custom profiles for production volumes and machine solid heat sinks for low-volume and prototype programs.
Do you supply RF shields ready for installation?
Yes. Shields are supplied with the requested plating and identification markings, kitted and labelled for SMT placement.
What accuracies can you hold on test fixtures?
ICT and flying probe fixtures are produced on calibrated tooling, with first article reports showing probe-to-pad positional accuracy. Repeatability is checked before shipment.
Can you handle a sheet metal run of a few hundred parts?
Yes. Low-volume sheet metal runs share the same tooling and inspection plan as production runs, which means moving from prototype to volume is a scale change, not a quality change.
Do you offer conformal coating or potting?
No. Conformal coating, potting and any electrical test are handled downstream. We deliver mechanical assemblies ready for your electronics integration line.
