Silver-plated wire for our coaxial lines. Diameter has been consistent batch after batch, and every pallet arrives with its inspection report.
We moved our nickel strip from a trading company to MYM. Same spec, lower price, and I now talk directly to the people running the line.
They matched our 19-strand construction to the drawing first time. Samples arrived in about a week.
Nickel-plated wire for high-temperature leads. Plating adhesion and solderability have been stable since our first order.
Clear answers on tolerances and RoHS paperwork before we placed the first order. That saved us weeks of back and forth.
Fast, technical replies on every question about plating and stranding. It feels like talking to our own engineering team.
Tin-plated copper wire for PCB jumpers. Spools are wound cleanly, with no tangles on our automatic feeders.
Pure nickel strip for our power tool packs. Weld quality is consistent and they hold the width tolerance we asked for.
Alloy wire for heating elements. Resistance per metre is within spec on every lot we have tested.
When we changed plating thickness mid-project, the change went straight to production. No lost week.
Reliable monthly volumes for our motor winding lines, and wooden-case packing that survives the sea freight.
Factory pricing and a quality report with every batch. Exactly what we wanted from a direct supplier.
Join manufacturers in more than a dozen countries buying direct.
Tell us what you need. We confirm we can make it, then quote. Samples and a factory audit are there whenever you want them.
