The Dual-Line Pocket Spring Assembly Machine is an automatic solution for bonding pocket spring rows into mattress and sofa spring units. It supports connection to one or up to two pocket spring coiling machines, enabling flexible and efficient production. With ultrasonic welding, servo-controlled gluing, and automatic fabric cutting, it ensures high precision and reduced material waste. Ideal for manufacturing high-quality zoned spring units with consistent performance.
The Dual-Line Pocket Spring Assembly Machine is engineered for bonding pocket spring coil rows to form a complete spring unit—an essential support structure used in pocket coil spring mattresses and sofas. This machine can be linked with one or up to two pocket spring manufacturing machines, enabling flexible production line configurations based on different manufacturing needs.
Once the pocket springs are produced, they are ultrasonically sealed and then arranged into rows. These spring rows are glued together by the assembly machine to form a stable and uniform pocket spring unit—the core of any high-quality mattress or sofa, and the key component responsible for comfort and support.
This Dual-Line Pocket Spring Assembly Machine features intelligent zoning through a touchscreen control panel. When connected to two spring manufacturing machines, each producing springs with different characteristics—such as one using harder wire and the other using softer wire—you can define custom zones across the mattress unit. By adjusting parameters like wire diameter, coil height, number of turns, and spring shape, manufacturers can precisely control the softness and firmness of each zone. This makes it possible to assemble a bed net that provides targeted support and comfort by combining different types of springs within a single unit.
Specifically designed for the production of pocket spring mattresses and sofas, this machine enables automated, high-efficiency bonding of spring rows with advanced control over spring arrangement and comfort zoning.

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!
