The automatic bonnell spring coiling & assembly machine is a fully automated production line designed for manufacturing double-cone Bonnell spring units used in mattresses, sofas, and furniture. From raw wire feeding to complete spring-unit formation, every step—including coiling, knotting, heat treatment, row alignment, and unit assembly—is integrated into a seamless workflow without any manual spring handling.
Powered by advanced CNC control and full-servo motion systems, the machine delivers high-speed and high-precision output, producing up to 90 springs per minute. The servo-driven six-manipulator transfer mechanism ensures accurate spring positioning, stable coil transfer, and minimal deviation, while the intelligent real-time fault detection system guarantees safe, continuous, and efficient operation.
The assembly section automatically arranges the coils into rows and pushes them into the stringing workstation with precise alignment. With adjustable spring height (80–230 mm), 4–7 coil turns, customizable waist diameter, and a heavy-duty 1000 kg wire capacity, the machine adapts easily to various mattress and sofa designs. Dual touchscreen panels and a wireless controller provide convenient parameter control, diagnostics, and operation management.
Ideal for manufacturers seeking higher automation, stable quality, and large-scale Bonnell spring production, this all-in-one solution delivers enhanced durability, efficiency, and long-term reliability backed by KIMKOO’s industry expertise.
