Our Company

Brand Startup & Dual-zone Industrial Layout
Founded in Xiamen in 2015, Aleader devoted itself to R&D and manufacturing of new polyurethane materials, then built self-owned standardized manufacturing parks in Longyan to form two core hubs for research and mass delivery. The group runs two differentiated independent business units. Its Xiamen R&D branch settles in the research platform of CAS Haixi Rare Earth Institute to communicate with material experts regularly and launch long-term industry-university-research projects. Two workshops operate in Longyan: the main workshop mass-produces full PU fittings for mobility aids, while Xinyonghua branch develops PU/PIR ventilation insulation boards for central air conditioning, supplying duct accessories and on-site installation guidance to accept custom orders for two industries concurrently.
Revenue Distribution & Application Scenarios of Five PU Categories
The revenue proportion of five core PU products is distinct: microcellular solid tires account for 70% of total shipments, high-resilience foam blanks and integral skin accessories each take up 10%, PU sponge raw materials and rigid fillers for carbon wheelchairs each make up 5%. Micro solid wheels serve leading manufacturers of electric wheelchairs and intelligent robots worldwide long-term; high-resilience foam materials steadily supply global Sealy memory pillow lines; integral skin parts can be customized for medical armrests and infant safety seats; rigid fillers fit carbon wheelchairs, competitive fishing tackle and lightweight aircraft model parts.


School-enterprise Co-research Platform & Expert Technical Backing
In 2023, we built a standard shared R&D lab together with Xiamen Rare Earth Institute, CAS, developing patented new polymer materials for mass production relying on shared lab space. We also maintain long-term in-depth technical cooperation with Professor Tang's research team from Sichuan University to tackle two core topics: modified polyurethane and innovative foaming systems. Our internal R&D team has over 20 years of hands-on PU manufacturing experience, capable of independently finishing formula iteration, custom mold development and full-range product upgrading.

Precision 12.5-inch Size & Unique C628 Tread Pattern
This genuine Chengshin 12.5-inch foam filled tyre adopts exclusive C628 full-surface tread design, tailored for medium-large load light transport equipment. The densely arranged curved tread blocks deliver reliable traction on dusty ground, rugged pavement and uneven outdoor road surfaces. It features dual color options of classic black and non-marking grey, fitting industrial operation areas and indoor public environments without leaving floor scratches. Every tyre is produced under strict size calibration, offering accurate interchangeability for original equipment updates and routine part replacements.
Integrated PU Foam Infused Structure for Fail-Safe Use
Constructed with one-piece polyurethane foam infusion technology, this tyre abandons traditional air chamber and inner tube setup. The fully filled foam core forms a solid, supportive interior structure that resists punctures, cuts and pressure loss completely. It eliminates all common downtime risks caused by defective pneumatic tyres. Different from overly rigid solid tyres, it retains mild cushioning performance to soften road shocks, delivering smoother movement with zero inflation checks and regular maintenance.
