Custom Cold-Formed Micro Components Built for Precision, Volume, and Performance
Sussex Wire specializes in manufacturing precision cold-formed micro-components for critical applications across medical, electronic, and high-reliability industries. We partner with engineers early in the design process to develop cost-effective, scalable solutions—helping you meet tight tolerances, material specifications, and performance requirements without compromise.
With in-house tooling, U.S.-based production, and support for specialty materials, we manufacture components in diameters from .007" to .400" and lengths from .040" to 3.00", with tolerances down to ±.0003". Whether you're prototyping a new part or scaling to millions, we deliver consistency, traceability, and quality at every stage.

End-to-End Manufacturing for Micro-Scale Precision
Our core process is cold heading, supported by a full range of precision manufacturing operations. This allows us to create complex geometries with minimal material waste, superior strength, and faster cycle times than traditional machining. Our manufacturing capabilities include:
Cold Heading / Cold Forming – ÌýOur primary process - ideal for high-volume production of precision components with excellent material efficiency and strength.
Fourslide & Multi-Slide Forming – Used for small stamped or formed parts with complex bends, folds, or multi-plane geometries.
CNC Screw Machining – Enables secondary operations and complex features not suitable for cold forming alone—tight tolerances, threads, undercuts, and more.
Thread Rolling & Tapping – Cold-worked threads that offer better fatigue strength and finish than cut threads—available in single or multi-thread configurations.
Wire EDM Cutting – Ideal for tight-tolerance trimming or slotting of difficult-to-machine materials with high precision and clean edges.
Roll Forming – Used to shape detailed profiles in small parts requiring consistent cross-sections.
Bending – Precision forming of wire and strip components for complex shapes and multi-axis applications.Cleaning, Finishing & Plating – Full range of part finishing operations to meet cosmetic, functional, and corrosion resistance requirements.
Cleaning, Finishing & Plating – Full range of part finishing operations to meet cosmetic, functional, and corrosion resistance requirements.
Dimensioning & Tolerancing – Final dimensional adjustments to ensure components meet exacting performance standards and fit.
Value-Added Services
In addition to our core manufacturing capabilities, Sussex Wire provides a range of value-added services that support your project from concept through delivery. These services are designed to streamline development, reduce lead times, and ensure production success—whether you're building a prototype or scaling to full volume.
