We manufacture precision-engineered bobbin components used as coil formers for winding wires in transformers, inductors, relays, and other electromagnetic devices. Designed to ensure dimensional stability, electrical insulation, and easy winding, our bobbins are available in various thermoplastic and thermoset materials such as phenolic, nylon, PBT, and glass-filled polymers.
Our bobbins are offered in standard as well as customized shapes and sizes, including single-section, multi-section, and surface-mount designs, meeting global insulation and flame-retardant standards. They serve as the foundation for efficient coil winding and enhance the performance of magnetic devices.
Features of Bobbin
High Dielectric Strength: Excellent electrical insulation prevents short circuits and ensures safety.
Thermal Resistance: Heat-stable materials withstand soldering, high operating temperatures, and continuous duty cycles.
Mechanical Stability: Rigid and dimensionally stable structure supports precise wire winding and long service life.
Flame Retardant Grades: Available in UL-approved materials for safety in electrical and electronic devices.
Variety of Configurations: Vertical, horizontal, multi-slot, and custom cavity designs for different applications.
Ease of Winding: Smooth surface finish and accurate slots allow uniform winding of copper/aluminum wires.
Cost-Effective: Molded designs reduce assembly time and increase production efficiency.
