Box Build & Electromechanical Assembly

Built for purpose. Box builds, panels and integrated systems assembled with precision.

From single-box units to full control panels and rack assemblies, we support customers with complete electro-mechanical builds tailored to their design and purpose. Whether you're building critical infrastructure, complex control systems or ruggedised field equipment, our team takes pride in building it right - first time, every time.

We’re here for your first prototype, your 100th production run, and everything in between.

Box Build Assembly

We assemble complete box builds and enclosures, integrating cable systems, switches, sensors, relays, circuit boards and mechanical parts. Whether it’s one-off R&D prototypes or low-to-medium volume production, we deliver to your spec - on time and ready to install.

Panel Wiring & Integration

We support bespoke control panels and rack systems with neat, labelled wiring and tested interconnections. Our attention to detail ensures clean routing, strain relief, and easy fault-finding for end users or field service teams.

Component Placement & Assembly

We fit mechanical and electrical components with precision and consistency, working from detailed drawings or build guides. With in-house machining capability, we also manage cut-outs, fixing points and small mod work as needed.

Functional Testing

We build with testability in mind. From continuity and resistance checks to power-up and functionality tests, we verify performance before delivery. You can also supply your own test jigs or protocols - we’re flexible to your process.

Procurement Support

Need help sourcing parts? We can manage full or partial procurement of components, enclosures, fixings and connectors, or work from free-issue kits. Either way, you get full transparency and control over what’s used and how. We have an established, trusted supply chain that we are proud to source as locally as possible.

Quality

Each assembly is visually inspected and electrically verified. We follow process control, version management and change logging to ensure every build aligns with your latest spec. Our goal: zero surprises, maximum trust.

Expertise you can trust

We’ve built control boxes, interface units, test rigs and enclosures for industries from energy to defence. Our cross-sector knowledge means we know what “good” looks like and we don’t settle for anything less.

Flexibility

Whether you supply the full kit or just a drawing, we adapt our approach to what’s most useful to you. No two customers are the same and that’s fine by us.

Quality

Visual inspection, test documentation, build checklists: quality is embedded in our process. And we’ll work with you to meet your own requirements, however specific.

Capability

From simple plates to multi-surface enclosures, we’ve got the facilities and the know-how to handle your electro-mechanical build with confidence.

Need something specific?

From the moment you brief us, we listen, clarify, and problem-solve alongside you. Whether you're working from a spec sheet, CAD model or a product idea, we’ll work collaboratively to turn that into a reliable, manufacturable solution.
