About Company
We own more than 20 years of cumulative polyurethane material development experience, and have built two official long-term technical cooperation platforms:
Joint R&D Laboratory with Xiamen Rare Earth Research Institute, Chinese Academy of Sciences Certified joint research center established in 2023, jointly develop proprietary modified PU formulas and industrialize lab research outcomes
Long-term technical cooperation with Sichuan University College of Polymer Science and Engineering We work closely with Professor Tang Jialing from the polymer engineering discipline, who guides raw material formula tuning, tire structural optimization and new product performance iteration. Our in-house professional R&D lab is fully equipped with SEM scanning electron microscope and precision material testing instruments, enabling independent microscopic foam structure analysis and material performance testing without external third-party outsourcing.
We built an in-house full-performance testing workshop with over 12 sets of professional testing machines to conduct full-link quality verification before goods shipment:
- Microscopic dimension vision measuring machine
- Stone crushing impact tester
- Lateral side impact & wheel runout detector
- Akron standard abrasion testing machine
- Continuous rolling smoothness endurance tester
- Salt spray corrosion resistance cabinet
- UV accelerated aging test chamber
- Constant temperature & humidity programmable test box
- Universal tensile strength testing machine
- Pressure rebound recovery test equipment All raw material batches, semi-finished tires and finished wheel assemblies pass full item testing before entering packaging procedures, to guarantee consistent product stability for overseas buyers.
Authorized Global Certifications
- ISO 9001:2015 Quality Management System Certification, valid for full PU wheel manufacturing business
- All finished tires pass RoHS & REACH international eco-environment testing (SGS issued official reports)
- Mobility aid tires comply with ISO7176, GB/T18029 medical equipment safety standards
- Bicycle PU tires obtain TUV safety certification
- Infant-contact foam accessories meet EU GS product safety norms
Full-Link Quality Control Mechanism
We set up standardized written control documents covering raw material incoming inspection, production process supervision, semi-finished sampling, finished product full inspection, defective product handling and after-sales corrective measures. Every production link has fixed operation guides to lock stable quality standards for mass orders.
We aim to set unified industry benchmarks for polyurethane mobility wheel manufacturing, and continuously expand global market coverage through technical innovation and standardized full-cycle service. Sticking to independent material formula research and customized one-stop PU component solutions, we plan to deepen cooperation with global rehabilitation equipment, intelligent transport and light mobility brands. We strive to become a leading global supplier of polyurethane mobility materials, delivering stable, high-performance customized wheel products to partners worldwide.
Main Product Profile
This damage-resistant polyurethane wheel assembly abandons air-filled cavity construction entirely, forged via one-step microcellular PU integral molding craft. Its compact dense matrix eliminates all hidden troubles caused by air-dependent tires, especially puncture breakdowns triggered by road sharp debris. Custom-modified polyether polyurethane raw stock delivers balanced flexible buffer and load-bearing rigidity, fitting low-speed mobility equipment running indoors and outdoors. Every finished wheel undergoes multi-stage performance calibration before shipment, delivering steady long-cycle operation without routine inflation or patch maintenance work for equipment brands and end users.
Unlike thin air-retention sidewalls on regular inflatable tyres, our wheel adopts gradient density microcellular internal layout. The outer contact layer features high-hardness anti-cut compound to block nails, metal scraps and broken glass from piercing deep into the core. The elastic inner foam matrix possesses strong rebound recovery capability; even if sharp fragments scratch the surface, the compact PU mesh structure will shrink back automatically without forming persistent leakage holes. No air chamber exists inside the wheel, so surface scratches will never lead to sudden loss of support capacity during travel.
This puncture-proof PU wheel covers diversified light transport machinery and rehabilitation apparatus, serving as original factory supporting parts and aftermarket replacement fittings:
- Medical mobility equipment: Manual & electric wheelchairs, walking aids, hospital patient transfer trolleys
- Daily travel gadgets: Elderly mobility scooters, portable baby strollers, light electric auxiliary carts
- Intelligent handling hardware: Service robot drive & caster wheels, warehouse small transport trolleys
- Light industrial machinery: Mini gardening equipment, portable fishing gear carriers, small model aircraft brackets
