Every great product starts with great materials. At our factory, we select high-standard steel pipes and metal materials to form the backbone of our folding wagons. Through precision cutting, we ensure that every component has consistent dimensions and minimal error margins. This attention to detail at the very beginning sets the stage for a perfectly assembled final product.
Once the materials are cut, they move to the next stage where they are transformed into robust frame structures.
Punching and Bending: Using high-speed punch presses and automatic pipe bending equipment, we process the metal into stable, durable frame components. This step lays a solid foundation for the load-bearing capacity and safety of the entire wagon .
Welding: All key structural parts undergo professional welding techniques. Every weld seam is a promise—a guarantee of strength, safety, and long service life .
Powder Coating: The frames then receive an environmentally friendly powder coating. This process enhances rust resistance, wear resistance, and overall texture. It also allows us to support custom color requirements for our clients .
One of the secrets to our wagons' durability lies in how we connect the parts. For many key connection points, we use rivet structures rather than simple screws.
This choice significantly enhances the load-bearing capacity and service life of the entire wagon. Even under frequent folding or heavy-load usage, the structure remains stable and does not loosen over time. It is a small detail that makes a big difference in real-world performance.
While the frame takes shape, other components are processed simultaneously.
Fabric Cutting and Sewing: High-strength fabric is precisely cut and sewn to create the wagon body. We carefully balance load capacity, comfort, and durability in every stitch .
Injection Molding: We use high-strength engineering plastics formed in one go through injection molding. This process ensures a smooth appearance while maintaining exceptional strength and durability .
Wheels and Accessories: Wheels and other components are processed and installed with the same attention to quality.
In the final assembly stage, all components come together on our assembly line. The push handle, brakes, side pockets, canopy, wheels, and more can all be flexibly customized according to customer requirements.
Before leaving the factory, every finished product undergoes strict inspection and testing. Standardized packaging ensures safe transportation and on-time delivery, so your folding wagon arrives in perfect condition, ready for adventure.
We are not merely product manufacturers—we are reliable long-term partners. Every folding wagon that leaves our factory represents decades of experience, meticulous craftsmanship, and a commitment to quality.
