Products Description
Item Basic Specification Overview
This 10x2.50-7 foam encapsulated rubber wheel is tailor-made rear wheel replacement accessory for medium-sized powered mobility scooters. The complete wheel assembly follows a dual composite construction: original brand rubber outer tyre matched with centrifugal cast microcellular polyurethane elastomer inner filling. The standard dimension 10x2.50-7 fits most common 7-inch hub frames, and we support matching aluminium alloy wheel rims for integrated delivery. Sourced mature rubber shells from Cheng Shin guarantee consistent surface abrasion resistance for long-term daily commuting use.
Ditching traditional inflatable inner tubes, this airless foam encapsulated wheel brings multiple user-friendly merits. Compact filled foam layer blocks glass fragments, iron nails and gravel to avoid puncture failures. The microcellular PU medium absorbs rolling vibration and running noise effectively, offering gentle riding experience. Solid integrated structure removes worries of air leakage and sudden tyre collapse, requiring zero inflation, pressure inspection or patching maintenance throughout service life.
We rely on rotary centrifugal pouring technology to inject polyurethane foam material into rubber tyre shells. Driven by rotational force during production, foaming raw materials form graded density inside the tyre cavity. The ground-contacting tread section solidifies into a compact, wear-resistant layer, while the curved sidewall maintains soft elastic texture to fit daily bending deformation. The microporous filling substance spreads uniformly without local gaps or uneven agglomeration, delivering consistent shock-absorbing performance. This well-balanced internal structure effectively offsets road bumps and vibration, bringing stable, silky rolling experience for mobility equipment users in all usage scenarios.
To eliminate hollow gaps inside finished foam tyres, we carry out standardized tyre pre-forming treatment ahead of filling procedures. Our centrifugal rotary filling method pushes polyurethane raw materials to spread evenly across the entire tyre cavity, achieving tight seamless adhesion between rubber casing and foam core to prevent hollow spaces from forming. We follow strict sampling inspection rules: each batch material change or equipment restart triggers a destructive cutting test on one sample tyre. Technicians visually examine the inner bonding layer thoroughly to confirm zero hollow pockets and delamination faults before mass production proceeds.
Company Introduction
Brand Overview & Nationwide Industrial Distribution Framework
Established in 2015, Aleader initially launched its polyurethane manufacturing division based in Xiamen. In 2023, the core mass-production workshop relocated to Longyan Industrial Innovation Zone, creating a dual-site operation system combining central research hub and large-scale production campus. The group runs two separate professional subsidiaries with distinct business directions. The Xiamen office resides within the CAS Haixi Rare Earth Research Institute, functioning as central material testing lab and external technical collaboration platform. Longyan UNT subsidiary specializes in PU thermal insulation boards and supporting installation fittings, while the primary Longyan factory solely develops microcellular PU wheels for rehabilitation mobility gear, building a dual development layout spanning mobility spare parts and construction thermal insulation materials.
Full Product Matrix & Market Sales Structure
Rooted in customized polyurethane modification and molding techniques, our business covers five categorized product lines with targeted market positioning. Specially crafted microcellular PU solid tyres stand as our staple offering, contributing 70% of total sales. High-elastic foam blanks and integral skin molded accessories each make up 10% of revenue, while PU sponge raw materials and carbon fiber wheelchair rigid foam fillers individually account for 5%.
Our PU wheel products provide stable OEM support for global electric wheelchair, mobility scooter and service robot manufacturers. We also supply high-elastic foam materials to international bedding giant Sealy. Our custom molded foam parts are widely used in medical auxiliary parts, rehabilitation cushions and infant safety equipment, with rigid foam fillers ideal for carbon fiber wheelchairs, fishing gear and aviation model accessories.
Whole-Chain Quality Supervision Mechanism & Global Authorized Compliance Credentials
The factory strictly abides by ISO 9001:2015 management specifications to build a full-cycle quality supervision loop, including raw material incoming verification, on-site production tracking, random sampling of semi-finished goods, comprehensive finished product checks and traceable after-sales quality records. Standard operating manuals standardize all production and testing procedures across workshops. Our goods hold multiple official accreditations: mobility wheels conform to ISO7176 and domestic GB/T18029, bicycle PU tyres gain TUV safety approval, and infant foam fittings meet EU GS criteria. Third-party lab SGS issues all eco-performance reports, clearing customs entry barriers for European, American and Southeast Asian importers.
Dedicated Client Support Team & Multi-Type Procurement Cooperation Plans
We reorganized internal business modules and split customer liaison work away from sales groups to form a dedicated service team with exclusive standardized service procedures. This team manages all-round buyer communication tasks: pre-production technical drawing confirmation, sample production progress updates, mass production schedule supervision, and after-delivery assembly technical guidance. We provide customizable cooperation forms to match varied procurement requirements: tiny trial lots for prototype verification, medium restock shipments for brand distributors, and large-volume customized OEM manufacturing for whole equipment factories. Our yearly production capacity stands at approximately 2 million sets of PU wheels and matching foam parts, with reliable output efficiency to sustain long-term bulk stocking partnerships with overseas clients.
