Capabilities

We custom wind by machine and by hand. We source through a vetted supplier network to locate the parts you need. Below is what we run most weeks. Not the limit of what we can do.

Typical volume
20 to 200,000 units
Sourcing
Part type
Toroids, split cores, C and U cores, bobbins, plastic housings and enclosures, terminals, lead wires, insulation, hardware, and custom components
Capabilities
Grain-oriented silicon steel, nickel alloys, ferrite, and powder cores • Custom and off-the-shelf components • Custom injection molding and tooling
Typical volume
Project-specific • Small first runs welcome, scaling to full production

Stretch Projects

The part that isn't on the list is often the one we like best.

Unusual winding, nonstandard geometries, legacy components, hard-to-source materials, or a supplier problem you’ve been dreading.

Not every challenge has an easy answer. But you'll get our thoughtful review, honest communication, and serious effort to move you forward.

Some examples of our latest work include:

A Tight Cavity

A customer came to us with a bobbin their previous winder couldn't get right: the winding choked the cavity, and every core insertion was a slow fight on the assembly line. Our winder developed a pattern that holds the cavity open, same spec, same wire, and assembly moved at speed again.

A Supplier Error

A lot came in defective, and the trail led upstream, across a border, to a supplier's process. We worked with them to correct it, wound a fresh batch, and shipped the replacements to our customer free of charge within two weeks, a process that normally takes 6 to 8 weeks.
