INDUSTRIES SERVED
Metro Assemblies has been manufacturing custom wire and cable assemblies for OEMs and contract manufacturers since 1971. From Fortune 50 corporations to emerging startups, we serve companies across six industries — delivering ISO 9001 certified assemblies with competitive lead times and USA-based production.
Industrial & Factory Automation
Control panels, automation equipment, and industrial machinery need assemblies that hold up under vibration, heat, and heavy-duty cycles. We build wire harnesses and cable assemblies for industrial OEMs, with potting and overmolding options for environments where standard assemblies fail.
Relevant capabilities: wire harnesses, cable assemblies, terminal crimping, potting/waterproofing, ultrasonic splicing, box build
Telecommunications
Telecom infrastructure runs on volume and consistency — two things our automated wire processing and quality assurance systems are built for. We produce multi-conductor, coaxial, ethernet, and ribbon cable assemblies for telecom OEMs and infrastructure suppliers, tested to spec before they ship.
Relevant capabilities: cable assemblies, wire processing, automatic wire cutting & stripping, electrical testing, quality assurance
Medical Device & Healthcare
Precision, traceability, and compliance aren't optional in medical manufacturing — they're the baseline. We produce cable assemblies and wire harnesses for diagnostic equipment and patient monitoring systems, backed by ISO 9001 certification and full testing before every shipment.
Relevant capabilities: cable assemblies, wire harnesses, insert overmolding, electrical testing, prototyping
Agriculture & Off-Highway Equipment
Tractors, combines, and construction equipment work in mud, moisture, and temperature extremes that destroy standard assemblies. We build ruggedized wire harnesses with waterproofing, potting, and overmolding built in — so your assemblies survive the conditions your equipment was designed for.
Relevant capabilities: wire harnesses, cable assemblies, potting/waterproofing, insert overmolding, terminal crimping, sleeving & heat shrink
Automotive
Automotive wire harnesses live inside vehicles for decades — exposed to heat cycles, vibration, and moisture that expose every weak crimp and loose termination. We build harnesses for automotive OEMs and Tier 2 suppliers who need USA-based production, consistent quality, and a manufacturing partner that can scale with their program.
Relevant capabilities: wire harnesses, terminal crimping, ultrasonic splicing, sleeving & heat shrink, electrical & mechanical testing, insert overmolding
Defense & Military
Defense applications demand documented quality, consistent performance, and zero shortcuts. Our UL ZPFW2/8 listing and ISO 9001 certification support the compliance requirements common in defense supply chains, and we work with engineering teams early to ensure assemblies meet program specs.
Relevant capabilities: cable assemblies, wire harnesses, electrical & mechanical testing, insert overmolding, quality assurance processing
