The addition of a desktop metal printer has revolutionised our ability to rapidly solve complex problems.

We’re able to create complex geometry which is often impossible to machine and we’re amongst the first to benefit from this revolutionary technology.

Unlike laser-based 3D printing systems that selectively melt metal powder, our system extrudes bound metal rods—similar to how an FDM printer works. This eliminates the safety requirements often associated with metal 3D printing while enabling new features like the use of closed-cell infill for lightweight strength.

CNC machining

We can gain certification for, and test products to, the highest regulatory standards. From running a whole project to NQA1 nuclear quality standard to gaining CE approval for the products we produce (including ensuring we have the correct welding qualifications and certification for the project at hand) we’re capable of delivering whatever is required.

When we take on a highly regulated project, we ensure that all applicable regulatory standards are achieved and that all technical files, LTQRs, certification and testing are completed to the highest standard.

### Electrical design and manufacture

We can complete every kind of electrical design task from wiring a light switch to providing multidisciplinary industrial PLC / PC collaborative HMI control systems. We produce safe, legally compliant systems with the relevant CE or NTRL accreditation required.

For projects we design and build motor control systems, build control panels with Contactor and Variable Speed Drive controlled via PLC with digital and analogue I/O (input/output) and integrate switches, transmitters and indication. Emergency stop either hard wired or through the PLC network using Allen Bradley safety PLC I/O cards through Allen Bradley ‘Compact Guard Logix’ controller.

System control using Panelview HMI and discrete switching and indication.

Remote control supported by sensors and cameras.

### Hydraulic & commissioning services / Onsite breakdown support and installation

We have a number of service engineers available to assist with breakdowns, fault finding, general servicing and onsite welding alongside our installation team to undertake projects of various sizes ranging from a single component to complicated robotic machinery.

We stock and supply various hydraulic / pneumatic components such as - Pumps, Valves, Fittings, Hoses, Accumulators, Seals etc.

We repair and manufacture cylinders of all sizes and quantities as well as repairing hydraulic pumps, motors, valves etc.

We offer site surveys for accumulators to check conditions and pre-charges to generate an assessment to ensure your site is compliant with regard to the safety of accumulators. We also offer a refurbishment programme for the re-certification of accumulators

Hydraulic & commissioning

We use Kimla CNC laser-cutting systems, including the latest fibre machines which enable us to cut a wide range of materials. We’ve been cutting mild steel, stainless steel and aluminium for many years but the latest technology also enables us to cut copper, brass and bronze.

Our machine benefits from a complete liner drive motion system which improves cycle times but, moreover, creates near machining tolerances typically +/- 0.02mm in thinner materials.

This accuracy has enabled us to reduce the number of postprocess operations previously required.

**Mild Steels:** 0.5mm up to 25mm thick.

**Stainless Steels:** 0.5mm up to 20mm thick.

**Aluminium:** 0.5mm up to 10mm thick.

**Titanium:** 0.5mm up to 4mm thick.

**Maximum Sheet Size:** 3m x 1.5m.

While we stock a wide range of materials, we can also use customer-supplied materials if required. We offer rapid turnaround and bookings can be made either by calling Barrnon on 017683 53440 or using our online booking system.

Laser cutting

 From our conception in 2007 we’ve been creating disruptive technology. We love a challenge.

Here’s our roadmap of the many successful products we’ve developed over the years.

- Crisp flavouring technology

- Ultrasonic cleaning of sand from live shellfish

- Scallop catching and sorting systems

- Cockle picking technology

- Nuclear sludge fluidic removal systems

- Nuclear sludge dry waste recovery systems

- Modular self-building robotics for harsh environments

- BIDS – Barrnon Integrated Decommissioning Systems

Our proven approach delivers results to complicated problems that others don’t achieve.

At Barrnon, we specialize in producing harsh environment robotic machinery. Our mindset was founded in the commercial fishing industry and we’ve adapted our life experience to manufacture robots to tackle some of the world’s harshest radioactive environments.

Making simple work well is the ethos we adopt when we’re designing a new robotic system or end effectors. Transfer of proven technology from either nature or industry, wrapped into a robust solution is our trademark.

We have our own control system which can integrate into a virtual reality environment, giving an operator greater visibility of the task in hand.

Taking a wide range of sensory information in real time to anticipate consequence of potential action as well as blends of augmented, virtual and actual reality, allow our clients to reliably control complicated process to achieve consistent results.

Robotics

At Barrnon we have range of dedicated facilities to simulate predicted environments. From a nuclear fuel pond to an oil rig flare stack, our site can be configured to meet our clients’ needs.
