Division 01 · Precision engineering since day one
Fine Wire Winding.
Precision coil winding is where Supplar began — and it remains the technical core of our business. From 29 SWG through to hair-fine 52 SWG, our multi-spindle, AC servo-driven machines deliver the repeatable accuracy that relay, solenoid, sensor and ignition-coil applications demand.
Wound Components
What we build, live.
Switch between component families — each is wound turn by turn on the same servo-driven lines.
- Pick-up coils
- Relay coils
- Solenoid coils
- Transformer coils
- Pump windings
Wire Gauge Range
29 SWG down to hair-fine 52 SWG.
Our winding lines handle an exceptionally wide range of fine copper wire on the Standard Wire Gauge (SWG) scale.
Winding Machinery
Servo accuracy, automated.
Automatic multi-spindle coil winding machines produce linear-wound coils — relay, solenoid, rotor and contactor coils, ferrite-core transformers and ignition coils.
Multi-axis movement executes terminal wrapping, wire routing and wire gripping & cutting automatically, combining mechanical, pneumatic and electronic systems for high, repeatable performance.
- AC Servo AxesPrecise multi-axis motion for repeatable winding accuracy across the full gauge range.
- Automatic TwistingFully automatic rebound-structure twister for intricate winding patterns.
- Wide Coil TypesRelay, solenoid, rotor and contactor coils, ferrite-core transformers, ignition coils.
