Expertise / capabilities

From first idea to finished hardware.

From complete machinery and vehicle electrification to PCB and harness production, Curtis Instruments controls, rare parts, bespoke manufacture and early-stage product ideas. Choose a focused service or bring together multiple disciplines from concept to completion.

Machinery & vehicle electrification, batteries & power

Electrical system design and builds for machinery and vehicles, including replacement and bespoke battery packs, BMS integration, motor drives and power-system control. We consider mechanical integration, servicing, fault handling and protection as part of the whole system.

Wiring harness design, review & production

From reviewing a problematic existing loom through clean-sheet design and production of wiring harnesses. No-MOQ enquiries are welcome, from one-off prototypes and restoration jobs to repeatable production harnesses.

No minimum order quantity is offered subject to design, component availability and quotation.

PCB design, manufacture & assembly

PCB engineering from first circuit to production-ready electronics. Design, prototyping, manufacture and component assembly support, including coordination of repeatable and higher-volume builds.

Circuit design and component selection PCB layout for embedded and power applications Prototype board manufacture DFM and manufacturing liaison Assembly support from prototype to mass production Test considerations and technical documentation

Manufacture and large-scale assembly may be coordinated through suitable production partners.

Curtis Instruments product support & embedded control

Independent engineering support for equipment using Curtis Instruments products: application-layer software (including VCL where applicable), machine configuration, CAN communications, fault handling and system integration using appropriate manufacturer tools.

Product design & development

Product design from a sketch or rough requirement to finished hardware. We can help develop bespoke products, specialist equipment and one-off or production-ready assemblies across mechanical, electrical and software disciplines.

Concept and feasibility assessment Product design, CAD and technical architecture Electronics, software and mechanical integration 3D models, prototypes and iterative testing Design reviews, risk analysis and validation Manufacturing preparation and build documentation

Component sourcing & obsolete parts

Sourcing and remanufacture support for difficult, obsolete or unusual components, including specialist machine spares and rare car, motorcycle or performance parts. We can investigate stock, alternatives, reverse engineering, redesign and bespoke manufacture where technically and legally feasible.

Have an idea? We can help create it.

You may have identified a problem worth solving, but not know where to start technically. We can turn an outline, sketch or conversation into a scoped engineering brief, test its feasibility, create prototypes and help plan the route to production.

Specialist partner network

Not every request fits neatly within our direct capabilities. If we cannot take on the work ourselves, we may know someone who can. With your permission, we can explore an introduction to a suitable independent specialist; availability and suitability are assessed case by case.

Need a blended service package?

Most projects need more than one discipline.

Whether you have an idea, a machine to electrify, a wiring problem or a rare part to replace, bring us the requirement. We can define a practical route from first discussion to an engineered result.
