Electronics Industry CNC Machining

Device enclosures and unibody casings, internal brackets and mounts, thermal components such as heat sinks and cold plates, connector housings and contact bodies, and structural parts for mobile devices, computing hardware and wearables.

Yes, and it is one of the harder things to get right. On consumer electronics the machined surface is often the product surface, so tool marks, chatter and anodizing streaks are all visible defects rather than cosmetic ones. We plan the finishing pass around the surface that will be seen, and control the coolant, tool path and feed so the part anodizes evenly without blotching.

Standard machined tolerance is ±0.025 mm, with critical features such as connector interfaces and mating faces held to ±0.01 mm where the drawing requires it. For parts that must assemble with a PCB or a moulded component, we work to the interface dimensions that actually govern fit rather than tightening the whole drawing.

Metals: aluminium 6061 and 7075 for housings, stainless 303, 304 and 316, magnesium alloys for lightweight structures, and brass for connectors and contacts. Finishing includes anodizing and plating.

Polymers and advanced materials: ABS, polycarbonate, nylon and PEEK, plus titanium, copper alloys for thermal management, ceramics for insulating parts, and composites for specialised applications.

Functional prototypes run on a 2–4 day cycle for design verification and assembly testing. The same process then carries into volume production from 1,000 up to 500,000+ units, with full production records so the validated part and the series part are the same part.

Consistency is managed by process control rather than end-of-line sorting. Every part is produced against a locked process with a defined tooling and fixture set, critical features are measured with calibrated instruments and CMM, and results are trended across the run so drift is corrected before it becomes a non-conformance.

Yes. Consumer electronics work is usually pre-launch, so we sign unilateral or mutual NDAs before drawing review, restrict drawing access to project engineering personnel, and do not use customer parts for marketing or sample display. Nothing reaches a portfolio or a trade show without written authorisation.
