As a trusted custom wire harness manufacturer and custom cable assembly manufacturer, we partner with OEMs, industrial engineers, and technical buyers across the UK to deliver custom cable assemblies that meet the strictest electrical, mechanical, and environmental requirements.
Cloom Tech supplies precision-built custom cable assemblies to engineering firms, contract manufacturers, and OEMs across the UK. We work closely with buyers in aerospace, defence, electric vehicle development, automation, and control panels to support build-ready integration into complex electronic systems.
Our production team delivers bespoke cable assemblies with full traceability, competitive lead times, and compatibility with global component brands such as Molex, JST, Harting, and Hirose.
We provide custom cable assembly solutions that match the voltage, shielding, and mechanical protection needs of advanced assemblies across a broad range of industries. Our technical team fabricates to your exact specifications, offering flexibility from simple wire harnesses to full electro-mechanical sub-assemblies.
Each cable assembly supports both high-performance data and power circuits with options for overbraiding, sleeving, overmoulding, and potting. Whether you need a one-off build or scalable production, we can deliver cost-effective solutions without sacrificing compliance or quality standards.
We build custom RF cable assemblies UK using high-tolerance crimps, matched connectors, and precision shielding.
Our cleanroom processes support exact frequency, attenuation, and EMI isolation targets for signal-critical applications.
Our high-current cable assemblies power everything from motor drives to HVAC, automation systems, and tractor wire harness assembly applications.
With support for multicore routing, heavy-duty cable harness layouts, and robust insulation, each solution is made to endure continuous use and vibration.
We produce low-voltage data and logic signal cables, integrating components like strain reliefs, diagnostic leads, and waterproof IP-rated cable and harness terminations.
All cable assemblies are 100% electrically tested and inspected before shipment.
Cloom Tech provides custom cable assemblies UK that meet exacting mechanical, electrical, and environmental demands across various industries. We work from your drawings, samples, or specifications to deliver assemblies to meet your specifications—tested, documented, and ready for installation.
We support flat, twisted pair, coaxial, multi-core, and shielded options, tailored to each cable assembly need. This includes signal and power applications, with insulation suited for temperature, oil, and UV exposure.
Our tools support standard and miniature crimp styles for both open and closed barrel terminals, from high-current lugs to micro connectors. We can also pre-form wires, control crimp force, and conduct destructive testing to validate strength.
We build for indoor, outdoor, and ruggedised applications, offering potting, grommets, boots, and IP68 sealing where required.
All orders come with part tracking, inspection reports, and test logs to maintain your quality standard. This level of service supports regulated industries and ISO-based QMS audits.
Cloom Tech delivers custom cable assemblies manufactured under controlled, certified conditions using high-precision machinery and quality-controlled workflows. Our facility supports complex layouts, high-pin-count builds, and repeatable process control for low- and high-volume runs.
We support automated wire processing for gauges from 40AWG to 120 mm², using equipment that controls strip length down to ±0.2 mm. Multistage strip setups allow precise prep for multicore and shielded cables, including end-strip and mid-strip for splice locations.
Our lines include servo-controlled crimping presses with force monitoring and applicator systems tailored to Molex, JST, Hirose, and Harting terminals. Each crimp undergoes pull testing and visual inspection under magnification for deformation, burrs, and insertion force alignment.
We build both flat and 3D cable looms using form boards and guides to maintain length, bend radius, and chassis alignment. Routing is validated against your wiring drawings to avoid over-compression, twist, or over-extension of wires and connectors.
We offer quality cable assemblies using conductors like tinned or silver-plated copper, with insulation in PVC, XLPE, or silicone depending on your thermal and chemical environment. Shielding options include foil, braid, and composite layers. Sheathing and sleeving are matched to install conditions and bundling needs.
We offer overmoulding and encapsulation for strain relief, shock resistance, and ingress protection. Materials include silicone, PVC, and polyurethane, rated for high-humidity, chemical exposure, and high-vibration installations.
All cable assemblies undergo continuity, Hi-Pot, and insulation resistance testing using computerized test equipment. We also offer circuit-level tests for logic signal validation and function checks for assembled electronic systems, including box build options.
Cloom Tech operates under ISO 9001:2015 and UL certification frameworks, with all harness and cable assembly manufacture conducted by IPC/WHMA-A-620 trained personnel. We maintain traceability through batch records, issue full conformance reports, and support quality system audits for defense, automotive, and aerospace clients.
We’re a process-driven manufacturing partner for technical teams who need accurate, compliant, and fully tested solutions. From the first quotation to final delivery, we prioritize control, flexibility, and full traceability.
We manufacture cable assemblies to meet your specifications, whether you need high-current power distribution, sensitive signal routing, or mixed-application harnesses. Every product starts with your drawing and finishes with verified outputs.
With decades of experience, our technical team understands the demands of advanced electronic systems. From routing to testing, we apply proven methods to deliver consistent results.
We integrate parts from Molex, JST, Hirose, and Harting, sourcing through a controlled supply chain that avoids substitutions. This protects your BOM, approvals, and application-specific layout.
Our modular workflow handles single build samples, short-run production, or full OEM lines. Whether you need a custom-made cable or a full batch of control harnesses, we scale to match.
Our cable assemblies are tested to the highest industry standards, including Hi-Pot, insulation resistance, and functional testing under load. All procedures follow IPC/WHMA-A-620 for precision and reliability.
From enquiry through delivery, our team provides clear updates, technical guidance, and rapid response to specification changes.
All custom cable assemblies UK are tested to ensure electrical integrity, mechanical reliability, and compliance with your application’s exact requirements. We document every step and provide testing logs with each shipment.
Technicians check each cable assembly for insulation damage, poor crimps, missing labels, or misaligned connectors, using magnification and torque tools where required.
We use multi-circuit testers to verify full circuit paths, detect open or short circuits, and confirm signal line resistance values fall within tolerance.
High-potential (Hi-Pot) testing applies voltage across conductors and insulation to confirm that your cable assemblies meet isolation requirements and prevent arcing or breakdown.
Our team validates crimp strength and connector retention using calibrated tensile equipment to confirm retention under handling and vibration conditions.
Where applicable, we simulate field conditions by powering circuits under load and toggling connections to confirm full functional response before release.
