As a cornerstone of the mattress and furniture industry, the bonnell spring coiling machine revolutionizes the production of hourglass-shaped bonnell springs—renowned for their durability, balanced support, and cost-effectiveness. This advanced automated equipment integrates multiple manufacturing processes into a seamless workflow, becoming indispensable for high-volume production environments.
At its core, the machine streamlines spring production through four key integrated functions: wire feeding, precision coiling, servo-controlled knotting, and on-demand heat treatment . Equipped with CNC-driven coiling heads and PLC control systems, it delivers exceptional accuracy—producing 80 to 100 springs per minute while maintaining uniform coil shapes, tight knots, and consistent dimensions . The heat treatment module enhances spring elasticity by electrically tempering each coil, ensuring long-lasting rebound performance even under repeated stress .
Technical innovations elevate its usability and reliability. Worm and gear transmission with frequency control enables smooth, stable operation during continuous high-load work . User-friendly touch screens allow real-time parameter adjustments, while automatic lubrication systems extend component life and reduce maintenance needs . Safety features like protective enclosures and fault-detection shutoffs prioritize operator well-being without compromising efficiency .
Versatile by design, the machine accommodates wire diameters of 1.8–2.4mm, spring heights of 70–210mm, and 4–7 coil turns, adapting to twin, full, queen, and king-size mattress requirements . Its compact footprint and single-person operability make it ideal for both small workshops and large-scale factories. By eliminating manual labor and reducing curing time, it empowers manufacturers to meet global demand for quality mattresses and sofas while optimizing production costs.
In essence, the bonnell spring coiling machine merges traditional spring performance with modern automation, solidifying its role as a game-changer in the furniture manufacturing landscape.
