About Company
Brand Origin & Phased Industrial Layout Construction
Founded in Xiamen back in 2015, Aleader started its polymer production lines and gradually completed multi-site industrial deployment after years of expansion. Two core business branches take charge of distinct product tracks. The Xiamen research division settles within CAS Haixi Rare Earth Research Institute, functioning as an exclusive material research and trial platform. The Longyan flagship manufacturing hub focuses on developing and producing PU wheel accessories for rehabilitation mobility equipment. Meanwhile, the UNT subsidiary independently develops and produces PU/PIR ventilation duct insulation panels and matching installation accessories. This dual industrial layout balances cutting-edge material research and mass production of mobility spare parts and construction thermal insulation supplies.
Core Corporate Mission, Vision & Team Code of Conduct
Our brand mission is to deliver safer, more convenient and comfortable daily experiences to end users through advanced polyurethane material solutions. The long-term development vision is to become a globally recognized specialist focusing on PU material application technology. Three work principles guide all staff: follow the closed-loop logic of planning-execution-adjustment-re-implementation; persist in technological breakthroughs to realize sustainable long-term operation; create promotion opportunities for employees, generate commercial value for the enterprise and shoulder social responsibilities. The whole team adheres to four spirits: unity, dedication, ambition and perseverance.
Dual Academic Cooperation Platform & Independent R&D Competence
We maintain stable long-term technical cooperation with two authoritative polymer research institutions: Sichuan University College of Polymer Science and Engineering and the Institute of Rare Earths under Chinese Academy of Sciences. A joint material research lab was co-founded with Xiamen Rare Earth Institute in 2023, dedicated to developing exclusive customized PU formulas and converting lab polymer research into mass-producible finished goods. Professor Tang Jialing from Sichuan University's polymer major participates in product iteration, guiding raw material formula adjustment and wheel structural upgrading. Our internal technical team possesses over 20 years of frontline PU manufacturing experience, independently developing lightweight low-density foam, wet anti-slip tyres and self-sealing puncture-resistant tire materials to break performance limits of traditional polyurethane products.
Core Manufacturing Competencies & All-Round Client Support
We possess multiple standout strengths that benefit every global cooperative partner. As a self-operated production plant, we streamline internal scheduling to shorten production cycles and speed up goods dispatch. We welcome bulk wholesale batches, small trial consignments and low-volume test orders without rigid order thresholds. Our in-house technical crew boasts nearly 15 years of polymer development know-how, delivering targeted professional guidance for all mobility wheel projects. Bespoke wheel modification is available to match unique dimensional, structural and performance demands from buyers. Every wheel assembly comes with a full 12-month factory quality guarantee against production flaws. Our dedicated after-sales team offers timely troubleshooting guidance to resolve assembly hurdles remotely. All finished wheel products undergo authoritative testing to meet international RoHS and REACH environmental compliance benchmarks.
Global Brand Partner Network & Long-Term OEM Cooperative Clients
Our foam-filled wheel manufacturing workshop has built stable long-term matching partnerships with leading mobility and medical equipment brands covering overseas and domestic markets. Our international collaborative roster includes top rehabilitation equipment manufacturers such as Sunrise, Pride, Golden Technologies, Drive DeVilbiss Healthcare, Kymco, Roma Medical and LG. Domestically, we maintain consistent bulk supply ties with mainstream medical and component manufacturers including INTCO, MAOTIAN, LINIX, Innuovo, Chiaphua Components, KANGNI and JIANGTE MOTOR. Continuous repeat orders from these partners prove our reliable customization, mass production and quality control capacity.
Products Introduction
Overview of PU Foam Core Mobility Wheel Assemblies
This range of foam-filled wheel sets serves as standard rear wheel replacement parts for various powered rehabilitation wheelchairs. The whole wheel adopts a dual composite construction split into two functional layers: wear-resistant outer rubber casing and dense microcellular polyurethane elastomer filling core injected inside the tyre cavity. For consistent outer tyre quality, we exclusively source mature rubber products from two mainstream well-known manufacturers, Cheng Shin and Innova. The integrated foam filling eliminates flat tyre risks of conventional inflatable wheels, delivering steady load-bearing and smooth rolling performance for daily mobility aid operation.
Core Traits & Multi-Sector Matching Scenarios of PU Foam Core Tyres
Shortened as foam inserted tyres, this dual-component wheel combines commercial rubber outer casing and densely molded microcellular PU elastomer inner core. It stands out with all-round practical merits: no regular air refilling, strong resistance against sharp piercing, zero sudden deflation, excellent impact buffering and minimal routine upkeep. These tyres fit rehab mobility aids, elderly scooters, baby pushchairs, intelligent service robots, factory transport trolleys and light sports gear. Retaining the classic exterior texture of standard rubber tyres, it fully addresses the typical drawbacks of inflatable variants including puncture failures, slow air seepage and repeated daily servicing.
Centrifugal Casting Forming Craft for PU Foam Filled Mobility Tyres
We adopt centrifugal pouring molding technology to complete the internal foam filling of rubber tyres. Under rotary centrifugal force, the polyurethane raw material evenly adheres to the whole inner cavity of the rubber shell after foaming. This craft achieves differentiated density distribution: the contact tread layer forms a compact rigid structure for wear resistance, while the sidewall part retains soft elastic texture. Foam density is uniformly distributed without local hollow areas, bringing steady shock-absorbing performance. The balanced inner structure cuts road bumps effectively, delivering consistent smooth rolling experience for all mobility equipment end users.
