The Bonnell spring machine is a fundamental automated device dedicated to producing high-quality Bonnell springs, which are widely applied in mattresses, sofas and other upholstered furniture. As a staple in the bedding manufacturing industry, it efficiently fabricates the iconic hourglass-shaped spring coils that form the supportive core of traditional innerspring products.
This machine operates through a fully streamlined and precise production workflow. It first feeds and straightens high-carbon steel wire, then shapes the wire into standard hourglass coils via professional forming dies. After accurate cutting and heat tempering, the springs gain enhanced elasticity and durability. Finally, the built-in linking mechanism connects individual coils into integrated spring units, eliminating manual intervention and ensuring uniform product specifications.
Modern Bonnell spring machines adopt PLC intelligent control systems, allowing flexible adjustment of spring height, diameter and wire gauge to meet diverse production needs. Featuring simple operation, stable performance and high output efficiency, they greatly reduce labor costs and production errors compared with traditional manual processing.
Thanks to their reliable structural stability and cost-effectiveness, Bonnell spring machines remain indispensable for mass production of cost-effective bedding products. They support consistent product quality and high production efficiency, making them a preferred choice for medium and large furniture manufacturers worldwide, and continuously underpin the steady development of the upholstery manufacturing industry.
