This Bonnell spring assembly machine is used to link double-cone springs into complete Bonnell spring units for mattresses and sofas. It boosts efficiency, reduces labor, and supports different spring sizes.
This Bonnell spring assembly machine is designed for efficient and accurate production of Bonnell spring units used in mattresses, sofa cushions, and other upholstered furniture. Operators place the springs into the clamp tooling, while the machine provides stable mechanical assistance for linking, knotting, and helical wire processing. It connects upper and lower springs consistently, helping maintain uniform assembly quality across different product specifications.
The machine features durable, high-precision clamps and a servo-assisted wire feeding system that ensure stable movement, accurate tension control, and reliable wire cutting and end bending. Equipped with a Delta drive system from Taiwan, it delivers smooth performance and consistent output, even during long production cycles.
Interchangeable clamp components allow manufacturers to work with various spring diameters, heights, wire thicknesses, and unit sizes. The PLC-based monitoring interface provides essential status information and simplifies operation, reducing the technical requirements for operators while maintaining consistent assembly standards.
This equipment can be used as part of a complete Bonnell spring production line when paired with a Bonnell spring coiling machine. It is also suitable for factories that purchase pre-coiled springs and assemble the units in-house, offering flexibility and cost-effective production for different manufacturing scales.

When you plan to ship goods from our factory to your location, there are a few important aspects to consider in terms of transport options, delivery times, costs, and payment methods. Here is an overview of the shipping process:
Our nearest export port is Shenzhen Port. Depending on the destination port, the shipping duration can vary. You can inquire with your freight forwarder to determine the exact transit time and costs from Shenzhen to your port. For general reference, shipping by sea typically takes anywhere from 10 to 45 days, depending on the distance, shipping line, and specific routes. We also have established partnerships with reliable freight forwarders, but you're welcome to work with your own agent if you have preferred contacts.
Sea freight is the primary shipping method we use because it is the most cost-effective and reliable option for transporting large or bulk machinery. No matter which country you are in, sea freight can usually reach a nearby port—even if the local sea transport infrastructure is limited or less efficient.
Once the shipment arrives at your destination port, the shipping line will notify you to pick it up. You can simply ask your local forwarder or customs broker to handle the port clearance and truck the machinery back to your factory.
For customers within China, we typically ship machinery by land freight, including heavy trucks, semi-trailers, or railway transport.
For overseas customers, land freight is only possible if your country is physically connected to mainland China. While trucks and semi-trailers can generally transport machinery only up to the border, the key factor for cross-border delivery is whether a railway route exists to your country, or at least to a nearby transfer point where the cargo can then continue by truck into your region.
Air freight is generally not suitable for our machinery because the equipment is too large to fit into standard cargo planes. Even if the size allows, the shipping cost would be extremely high and impractical.
Instead, we use air freight mainly for shipping documents (such as B/L copies, invoices, packing lists) or for sending small spare parts, accessories, or consumables that customers may need urgently.
We offer several flexible payment methods to suit your business needs:
KIMKOO offer multiple types of pocket spring assembly machines — some can connect with 2 coilers, and others up to 3. Freely combine with pocket spring coiling machines of different speeds. Easily set up a 1-to-1, 1-to-2, or 1-to-3 production line to match your capacity. Customize your setup today!
