Frequently Asked Questions

What makes your machines suitable for audio transformer winding?

Our orthocyclic winding capability ensures consistent layer patterns critical for acoustic linearity and low distortion. Precise tension control prevents wire stretching that affects inductance, and programmable parameters ensure repeatable results across production runs.

Can you wind voice coils and guitar pickups?

Yes. We handle ultra-fine wire down to 0.02mm for voice coils, and support ECCA (enamel-coated copper-clad aluminum) wire commonly used in speaker applications. Our machines provide the consistent winding patterns essential for balanced tone and output in guitar pickups.

What types of coils can your machines wind?

Our machines handle transformers (power, audio, pulse, isolation), inductors, chokes, solenoids, motor coils, voice coils, sensor coils, and specialty windings. Capacities range from 10 mW to 10 kVA with programmable tension, speed, and layering patterns for orthocyclic, variable pitch, and multi-section winding.

What are your lead times?

Standard machines typically ship in 2-4 weeks. Custom configurations and special tooling may require 4-6 weeks. U.S.-based manufacturing means no overseas supply chain delays—we maintain inventory of common components to expedite orders when possible.

Do you provide custom tooling for unique bobbins?

Yes, we offer full in-house design, CAD modeling, simulation, and rapid prototyping. Our engineering team works directly with you to develop custom arbors, fixtures, and tooling for any bobbin geometry. Typical turnaround is 2-3 weeks for custom tooling.
