International Rolling Mills designs, builds, and refurbishes a comprehensive range of wire and rod processing equipment — with particular depth in wire & rod rolling mills, tandem wire & rod rolling mills, and wire flattening mills, which IRM manufactures new and refurbishes to factory condition. From bench-top laboratory wire mills for metallurgical R&D through multi-stand tandem production lines for specialty wire and rod, IRM provides the equipment and engineering expertise to process wire and rod in virtually any metal.
IRM's wire processing equipment serves a broad customer base — from aerospace and defense manufacturers producing precision wire for connectors and fasteners, to research institutions developing new wire materials for additive manufacturing feedstock, high-temperature superconductor (HTS) substrate tape, and next-generation energy applications.
IRM New-Build Wire Processing Equipment
IRM builds new wire & rod rolling mills, tandem wire & rod rolling mills, wire flattening mills, traverse winding machines, and bull block wire drawing machines to customer specification. Refurbishment and upgrades are available for all supported equipment types. Additional equipment — swagers, turkshead machines, wire drawing machines, and tube forming machinery — is available refurbished and used.
IRM’s wire and rod processing inventory spans new-build and refurbished core equipment through used specialty machines. Wire rolling mills and wire flattening mills are IRM’s primary wire processing products — built new, refurbished to factory condition, and serviced by engineers with direct operating experience on these machines.
New Build • Refurbished • Used
2-High and 4-High rolling mills configured specifically for wire and rod — reducing round stock, shaping wire profiles, and producing precision wire and rod in specialty metals from lab scale through production. The distinction between wire and rod is simply diameter; IRM builds and refurbishes mills for both, from fine precious metal wire through larger rod stock in refractory and exotic alloys.
New Build • Refurbished • Used
Multi-stand rolling mills with two or more roll stands in series, reducing wire or rod diameter in a single continuous pass. Tandem mills offer higher production rates and more consistent reduction than single-stand reversing mills for volume production applications. IRM builds new tandem wire and rod rolling mills and refurbishes existing tandem lines for specialty metals producers.
New Build • Refurbished • Used
Precision mills for converting round wire into flat or shaped ribbon strip — critical for brazing alloy preforms, electrical contacts, spring stock, and specialty electronic components. IRM builds and refurbishes wire flattening mills in a range of roll sizes and configurations for ferrous, non-ferrous, precious, and refractory metals.
New Build • Refurbished • Used
Single-block wire drawing machines for reducing wire diameter through a die under tension. IRM builds and refurbishes bull blocks for specialty wire production in precious metals, copper alloys, stainless steel, and other materials where controlled drawing is required.
New Build • Refurbished • Used
Precision winding machines for spooling wire and strip onto spools or reels with controlled traverse motion — essential for packaging fine wire in precious metals, specialty alloys, and electronic materials.
Refurbished • Used
Rotary swaging machines for reducing or shaping wire and rod through repeated die impact — used for pointing wire ends, forming tapers, and producing shaped profiles in a range of metals.
Refurbished • Used
Turkshead shaping machines, multi-die wire drawing lines, and tube forming equipment available in used condition. Turkshead machines are used for shaping wire and rod into square, rectangular, and custom profiles. Contact IRM to discuss specific requirements.
Wire processing has historically served established industries — jewelry, electrical, fasteners, springs. IRM is seeing a significant and growing demand from R&D programs and production operations developing entirely new categories of wire for next-generation technology applications. Two areas in particular are driving substantial equipment investment:
Wire Arc Additive Manufacturing (WAAM) and Directed Energy Deposition (DED) processes use metal wire as their primary feedstock — depositing material layer by layer to build components. As these processes move from R&D into production, manufacturers are developing custom alloy wires with specific composition, diameter, surface condition, and mechanical properties that standard welding wire suppliers cannot provide.
IRM’s wire rolling mills, wire flattening mills, and drawing equipment are used by research institutions and companies developing novel WAAM feedstock in titanium alloys, nickel superalloys, refractory metals, copper alloys, and other advanced materials where custom wire processing is required at lab and pilot scale.
Second-generation HTS wire (REBCO coated conductors) and first-generation wire (BSCCO) require precision rolling of metallic substrate tape as a critical step in their manufacture. The biaxially-textured metallic substrate — typically a nickel alloy — must be precision-rolled to develop the crystallographic texture that allows epitaxial growth of the superconducting layer.
As fusion energy, high-field magnets, and superconducting motor programs accelerate — driven by fusion developers and national laboratory programs — demand for HTS wire substrate processing equipment is growing rapidly. IRM’s precision rolling mills and wire flattening mills are suited to the dimensional precision and material control this application demands.
Wire and rod processing equipment from IRM serves the same broad range of specialty metals customers as IRM’s rolling mills and slitting lines — with particular depth in R&D and production applications requiring non-standard materials, tight tolerances, or custom processing configurations.
Wire rolling and flattening mills for gold, silver, platinum, and palladium wire — producing flat wire, shaped wire, and ribbon strip for jewelry, contacts, and precision components where material purity and surface finish are critical.
Precision wire in titanium, Inconel, beryllium copper, and specialty structural alloys for connectors, fasteners, springs, and actuator components. IRM equipment is used in facilities serving aerospace prime contractors and defense programs where wire dimensional accuracy is non-negotiable.
Wire flattening for brazing alloy preforms, solder ribbon, electrical contact strip, and precision electronic components. Manufacturers of brazing alloys and solder products rely on IRM wire flattening mills to convert round wire feedstock into flat ribbon and shaped preform stock.
Nitinol guidewires, stainless steel suture wire, titanium orthopedic wire, and other biocompatible specialty wire for medical devices. IRM equipment supports the precise diameter control and surface quality these applications require.
Universities, national laboratories, and corporate R&D programs developing new wire materials — additive manufacturing feedstock, superconductor substrates, shape memory alloys, and advanced functional wire — rely on IRM lab-scale and pilot-scale wire processing equipment for small-batch, high-precision work.
Molybdenum, tungsten, tantalum, niobium, and rhenium wire for high-temperature and specialty applications. Refractory metals require controlled rolling conditions and specific tooling — IRM’s engineering experience with these materials ensures the right mill configuration for demanding alloy processing.
Founded in 1978, IRM has decades of experience building, refurbishing, and servicing wire and rod processing equipment for specialty metals applications. Wire rolling mills and wire flattening mills are among our most frequently built products — engineered to the same standards as our rolling mills, with the same attention to rigidity, precision, and long-term reliability.
Wire processing at the precision end of the market — fine wire in precious metals, exotic alloys, and emerging functional materials — is exactly the work IRM has built its reputation on for over four decades.
Wire processing requirements vary widely — from diameter and profile to material, production volume, and precision requirements. Whether you need a new IRM-built wire flattening mill for brazing alloy ribbon, a refurbished bull block for precious metals drawing, or a custom-engineered wire rolling system for an emerging material application, IRM’s engineering team can help specify the right solution.
