Bonnell Spring Coiling Machine

The Bonnell spring machine is engineered for high-speed production of durable, hourglass-shaped springs used in mattresses and sofas. This machine integrates coiling, knotting, heat treatment, and spring output into a seamless process, ensuring consistent quality and efficiency in spring manufacturing.

Equipped with a CNC-driven coiling head, the Bonnell spring coiling machine can produce up to 90–100 springs per minute. Its precision worm and gear transmission system, coupled with frequency control, delivers smooth motion and stable speed, optimizing performance under continuous high-load operation.

The Bonnell spring assembly machine is designed to automatically knot the top and bottom ends of each spring, ensuring strong and uniform connections. The integrated heat treatment system applies electric heating to each spring during coiling, enhancing its elasticity and ensuring consistent, reliable rebound performance.
