Mattress Bonnell Spring Machines for Sale
A Bonnell spring machine is a piece of manufacturing equipment used to automatically produce the hourglass-shaped springs that form the core of Bonnell-style mattresses. These machines coil metal wire, often at high speeds and with precise computer control, and can also incorporate knotting, heat treatment, and assembling functions to create a complete bonnell spring unit for mattresses.
Function and Process- Coiling:
The machine uses a coiling mechanism to shape a length of wire into the distinctive hourglass form of a bonnell spring. - Knotting:
After coiling, the ends of the spring are knotted to secure the structure. - Heat Treatment:
The springs are often heat-treated to improve their strength and stability, ensuring they maintain their shape and function over time. - Assembly:
Some machines also integrate an assembly function, combining the individual springs into larger mattress units.
Types of Machines
- Automatic Machines:
Modern, highly automated machines with computerized control systems (PLCs) that handle all steps from wire coiling to spring assembly. - Semi-Automatic Machines:
Machines that automate some processes, like wire cutting and coiling, but may still require manual intervention for other steps. - Manual Machines:
Older machines require significant manual effort from the operator for most functions.
Key Features
- Precision Control:
Modern machines utilize servo motors and PLCs to ensure consistent spring size and shape. - Flexibility:
They can be adjusted to meet the specifications for different mattress sizes and designs. - Speed and Efficiency:
High-speed machines can produce many springs per minute, improving production capacity and reducing labor costs.
