How Custom Wire Forms Are Made: Understanding the Wire Form Manufacturing Process

Custom wire forms—precision-engineered metal shapes—are valuable components in industries such as automotive, medical, aerospace, and electronics. They function as springs, clips, retainers, and supports, crafted to meet strict performance and dimensional demands.

Understanding precisely how custom wire forms are manufactured, from CNC bending through finishing touches, can empower engineers, buyers, and product designers to make informed decisions.

Ace Wire Spring & Form Co., a family-operated, ISO 9001:2015-certified and ITAR-registered manufacturer based in Pittsburgh since 1939, specializes in producing custom wire forms (with no standard stock parts) tailored to unique project specifications using advanced multi-axis CNC machines and expert engineering support.

1. CNC Wire Forming and Precision Bending: The Foundation of Quality

CNC wire forming isn’t just the first step—it’s the foundation of the entire process. It ensures accuracy, enables complex geometries, and supports both rapid prototyping and full-scale production. When paired with expert engineering oversight, CNC wire forming lays the groundwork for custom wire forms that meet exacting standards across industries.

To begin the CNC wire forming process, raw wire—available in diameters from 0.003″ up to 0.625″ and in materials like stainless steel, carbon steel, copper, Inconel, and titanium—is fed into computer-controlled machines. These machines bend the wire into precise shapes with exceptional repeatability.

2. Coiling, Cutting, and Forming in the Wire Form Manufacturing Process

After the base bends are complete, the wire goes through additional shaping:
Coiling creates helical springs with controlled pitch and tension for compression, torsion, or extension applications.
Cutting ensures exact lengths, preparing wire for welding or integration into assemblies.
Forming introduces loops, hooks, and 3D geometries that transform straight wire into functional designs like clips, brackets, and retainers.
Ace Wire Spring & Form Co. customizes these operations to meet specific application requirements, from small prototypes to high-volume production runs.

3. Welding Wire Forms — Resistance, TIG, and MIG Techniques

For more complex assemblies, welding is used to create strong, durable joints:
Resistance welding provides fast, localized bonds that are ideal for thinner wires.
TIG welding produces clean, precise welds for medical, aerospace, or consumer products where appearance and integrity are critical.
MIG welding delivers strength and speed, especially for thicker or more structural wire forms.

Selecting the correct welding method ensures the wire form can withstand the stresses of everyday use.

4. Secondary Operations That Enhance Wire Form Performance

Wire forms typically undergo finishing steps to boost their functionality and safety:
Threading adds grooves for assembly with screws or bolts.
Chamfering smooths sharp edges, improving fit and reducing handling risks.
Heat treatment strengthens the metal, improving fatigue resistance and ensuring parts hold up in demanding environments.
These operations ensure wire forms are safe, durable, and application-ready.

Why the Wire Form Manufacturing Process Matters for Quality and Cost

• Every stage of wire form manufacturing adds value to the finished product:
• Precision and repeatability ensure consistency in critical applications.
• Customization means wire forms are engineered for specific tolerances and performance requirements.
• Material variety allows designers to select the right balance of strength, flexibility, and corrosion resistance.
• Prototype-to-production support enables design testing before scaling up.
• Quality assurance ensures compliance with industry standards, from ISO 9001 certification to ITAR registration.
