Double Wire Hook Winding Machine

Our KXT-700A double wire crochet hook winding machine is tailor-made for miniature toroidal common-mode choke & small bifilar transformer coil production, specially optimized to solve the core industry pain: two-wire staggered winding, inconsistent tension & low yield of manual bifilar wrapping which most standard single-hook winders fail to fix.

Different from ordinary hook winding equipment only supporting single wire intermittent winding, this model adopts our self-developed dual independent wire feeding + synchronous crochet hook structure, realizing one-step parallel winding of two enameled wires without crossover, targeting ferrite toroid OD6~16mm small core widely used in Korean/EU power supply, aerospace small transformer factories.

Suitable for mass & small-batch mixed production, widely adopted by Korean transformer & inductor manufacturers for bifilar coil processing.

✅ Exclusive Dual Independent Electronic Tension Control

Separate electronic damping tensioner for each copper wire, independent tension adjustment for two lines from 5g~80g, avoid tight-loose inconsistent bifilar winding caused by shared wire spool; effectively cut coil reject rate below 1.2%, ideal for triple-insulated high-temperature wire aviation-grade coils.

✅ Synchronized Single Crochet Hook Dual-Wire Guide Groove Design

Customized hook needle with double wire limiting groove, two wires fixed in respective track during full crochet stroke, completely eliminate wire crossing & twisting defects, winding turn error ≤±0.1turn, inductance uniformity far higher than conventional modified single-hook machine.

✅ Fast Fixture Switch + Multi-program Storage

One-key parameter storage up to 99 groups coil programs, core fixture replacement finished within 8 mins without mechanical calibration; support single wire, bifilar parallel, back-forth segmented winding three modes, switch between common-mode & differential-mode coil freely.

✅ Compact Cabinet Low Vibration Structure

Whole machine net weight only 100kg, integrated shock-absorbing base, running noise＜62dB, no floor fixation needed; 220V universal voltage compatible with Korea/EU 50/60Hz power grid, perfect for small factory limited workshop space.
