Hand Coil Winding involves manual forming and winding of magnet wire into coils for motors, transformers, and inductors. Skilled operators ensure precise geometry and insulation wrapping, suitable for low-volume or custom coil production.

Coil Processing covers specialised forming operations that shape, organise, bind, and prepare electrical- and magnet-wire coils for use in motors, transformers, inductors, and cable harnesses. These steps control wire geometry, strand distribution, consolidation, and insulation wrapping while preserving conductor integrity and dimensional accuracy.

Coil Processing

Coil Spreading uniformly distributes wound strands to achieve precise layer spacing, reduce hot spots and improve resin penetration. Fixtures mechanically or pneumatically expand the coil pack while maintaining conductor alignment and insulation integrity.
