Fine Material & Stable Physical Performance
We adopt refined polyurethane raw materials and adopt one-piece integral forming craft. There is no hollow space inside the wheel, and the material distribution is even across the whole body.
The formulated material maintains mild elasticity all year round. It will not become overly soft after long-term contact and compression, nor turn stiff under low temperature conditions. The surface does not produce sticky residue or faded scraps during long-term rolling, and stays neat after long hours of use. The material itself has no peculiar smell, suitable for long-term placement in closed living spaces.


Smooth Rolling & Effortless Movement
The outer running surface is designed with a gentle radian, which contacts the ground evenly. When pushing the matching equipment, users will feel smooth rolling with no obvious stagnation.
The subtle elastic property of the material can buffer tiny uneven spots on the ground. Even on spliced floor panels and slightly undulating ground, the movement stays gentle, without obvious jitter. The wheel creates minimal sound during operation, and will not form noisy interference in quiet living surroundings.
Daily Wear Resistance & Long Service Life
Built as a fully solid structure, this wheel avoids the hidden troubles brought by hollow air cavities. Fine gravel, tiny debris on the ground cannot cause damage to the wheel body, so there is no need to worry about abnormal running caused by surface damage.
The outer layer is optimized for daily friction. After repeated rolling day after day, the wheel surface wears at an extremely slow speed. The round outline remains intact for a long time, and the rolling feel will not change obviously with the increase of service time. It effectively cuts down the frequency of part replacement in daily use.


Wide Matching & Scenario Application
This specification wheel is widely matched with multiple types of small wheeled mobility devices. It works well for daily home-used wheeled aids and auxiliary mobile tools used in activity rooms.
It performs stably on wooden floors, ceramic tiles, plastic floors and ordinary cement ground. Whether used in family living spaces, community activity rooms or indoor public rest areas, it can adapt to different ground conditions and keep reliable running performance all the time.
Company Overview
Brand Footprint & Business Layout
Our business took root in Xiamen back in 2015, starting out as a manufacturer focused on polymer material finished parts. After two years of steady operation and market expansion, we transferred all production lines to Longyan in 2017 to expand production capacity and optimize operational arrangements.
In the following years, we kept expanding our business scale and setting up different operational branches. We have dedicated divisions focusing on wheel component manufacturing, new material R&D and production, as well as ventilation duct thermal insulation products. Our R&D team is stationed at a well-known domestic material research institute in Xiamen, building a linkage between technical research and mass production. Today, we operate multiple business lines, covering material development, finished product manufacturing and supporting services, forming a multi-dimensional business pattern.


R&D Strength & Academic Cooperation Network
We have built an experienced technical team who has been engaged in polymer material research and product development for more than 20 years. To keep updating our technology and exploring new material applications, we have established long-term cooperative relations with two major academic institutions.
We carry out joint research projects with the polymer research department of Sichuan University and the professional research institute under Chinese Academy of Sciences. Both sides share laboratory resources and technical experience, turning theoretical research into practical, marketable products. Relying on this collaborative model, we keep upgrading existing products and launching new styles, maintaining strong technical competitiveness in the industry.
Product Lines & Scenario Applications
We have developed a rich range of polymer products to cater to different industry demands. Our product lineup includes micro-elastic wheel parts, high-elastic foam components, integrated foam pieces, soft sponge materials and special filling parts for special equipment.
These products serve a wide variety of fields. Our wheel products have maintained stable cooperation with many overseas and domestic brands focusing on mobile devices and intelligent equipment. Our foam products supply famous international daily goods brands. Custom foam parts are widely used in auxiliary equipment and daily supplies. Special filling materials are popular among hobby users and equipment makers. All items are designed according to actual usage conditions to ensure stable performance in daily use.


Lab Resources & Full-Range Performance Verification
We are equipped with independent research labs and professional testing workshops inside the factory, furnished with more than ten sets of high-precision testing devices. These devices can complete abrasion test, impact test, ageing test, salt spray test and running state test, covering all core performance indicators of our products.
Every batch of goods will go through layer-by-layer inspection before delivery. Our products have passed mainstream international environmental assessments. Products used for daily travel tools and articles for special groups have obtained many globally recognized safety certifications. Strict testing standards ensure all products meet the access requirements of markets around the world.
Customized Solutions & Whole-Process Service
Besides standard mass-produced goods, we provide one-to-one tailored development services for clients with personalized requirements. Our technical staff can adjust material formulas, product sizes and surface styles according to samples, drawings and on-site working conditions provided by partners.
From initial scheme design, raw material matching to formal mass production, all procedures are finished inside our factory. Whether clients need minor parameter adjustments or full new product development, we can deliver practical solutions. The whole service process is streamlined, helping partners save time and operational costs.
