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.
