1. Features & Applications of Solid Foam Filled Tires
Foam-filled tires (FF tires) are composed of a durable rubber outer casing and high-resilience microcellular polyurethane elastomer inner filling. Combining the advantages of pneumatic tires and solid tires, these wheels require no inflation, are completely puncture-proof and flat-free, and deliver stable cushioning performance with zero daily maintenance and high safety reliability.
Widely applicable for wheelchairs, mobility scooters, baby strollers, service robots, tool carts and sports equipment, our foam-filled tires perfectly retain the traditional appearance and riding comfort of standard rubber tires. Meanwhile, they effectively eliminate the common drawbacks of air-filled tires, including easy puncturing, air leakage, sudden flat tires and frequent inflation and maintenance work.
2. Professional Production Technology: Spin-Cast Molding
We adopt mature spin-cast molding technology for internal polyurethane foam filling. This precision manufacturing process forms a dense, wear-resistant and firm tread surface, while maintaining proper flexibility on the tire sidewalls. The internal foam material is evenly and accurately distributed inside the tire cavity, delivering consistent and excellent shock absorption performance. This structural design ensures smooth, stable and comfortable riding experience for end users in daily use.
3. Strict Factory Testing Standards
To guarantee stable performance, long service life and high durability of all finished tires, we conduct a complete set of professional performance tests in-house during mass production:
Rolling drum endurance test
Tension and compression force analysis
Side impact resistance test
Drop resistance test
Static load bearing test
Circular track running test
Friction coefficient testing
Torque performance test
Running noise test
Bump road adaptability test
4. Product Certifications & Compliance
Our foam-filled tires and wheel assemblies fully comply with the ISO 7176 wheelchair safety standard and have passed authoritative RoHS and REACH environmental compliance tests. Selected models also meet German GS safety standards applicable to children's mobility products, ensuring safe and reliable use for global end customers.
5. Standard Assembly Process
We follow standardized and rigorous assembly procedures for all tire and rim finished products:
A. Pre-production Preparation Prepare qualified semi-finished tires, wheel rims, screws, nuts and other accessories; debug and calibrate assembly equipment to ensure production stability.
B. Precision Assembly Complete tire and rim assembly strictly in accordance with standardized operating specifications for foam-filled tire products to ensure assembly tightness and concentricity.
C. Finished Product Inspection & Packaging All finished wheels undergo strict side impact and runout tolerance tests. Only qualified products are cleaned, sorted and packaged for shipment.
