China Rubber Coated Magnet Manufacturer — Heavy-Duty Magnetic Holding Solutions by UPSUN
Our Rubber Coated Magnet Products

As a specialized China Rubber Coated Magnet Manufacturer, UPSUN engineers and produces high-strength rubberized neodymium magnets designed for demanding holding, mounting, and fastening applications. Every rubber coated magnet in our product line combines a powerful N35–N52 grade NdFeB magnet core with a ferromagnetic steel back plate and a precision-molded TPV (thermoplastic vulcanizate) or EPDM rubber shell, delivering vertical holding forces from 5 kg up to 350 kg per unit while protecting contact surfaces from scratches, dents, and paint damage. The durable rubber coating also provides exceptional corrosion resistance, UV stability, and waterproof performance — making UPSUN rubber coated magnets the ideal choice for both indoor and outdoor environments where reliable magnetic grip and surface protection are essential.
What separates a high-quality rubber coated magnet from an inferior one is the precision of the magnetic circuit design inside the rubber housing. At UPSUN, our engineers use alternating-pole NdFeB disc arrangements mounted on optimized steel yoke plates to concentrate magnetic flux on the working face, achieving pull-force efficiency far beyond that of a single bare neodymium magnet of the same size. The over-molded rubber encapsulation is then injection-molded under controlled temperature and pressure to ensure a seamless bond with zero air gaps, giving each rubber coated magnet consistent holding performance, superior shear resistance, and a professional finish ready for end-user deployment. Whether you need round rubber coated pot magnets, rectangular rubberized magnets with internal or external threads, cable-mount magnetic bases, or custom rubber coated magnetic assemblies, UPSUN delivers — direct from our China factory at competitive OEM pricing.

About UPSUN — Your Trusted Rubber Coated Magnet Supplier in China
Ningbo Upsun Magnetic Technology Co., Ltd. operates from Ningbo, China — a global center for permanent magnet manufacturing and one of the world's busiest deep-water port cities. With more than a decade of focused experience in NdFeB magnets, magnetic assemblies, and rubber coated magnet systems, UPSUN serves OEM, ODM, and wholesale partners across over 30 countries. Our vertically integrated facility covers the complete rubber coated magnet production chain: sintered neodymium magnet pressing and sintering, steel yoke plate machining, rubber compound formulation, injection over-molding, magnetization, and final assembly — all under one roof for maximum quality control and lead-time efficiency.
Quality is non-negotiable at UPSUN. We operate under a certified ISO 9001 quality management system and enforce rigorous incoming material inspection, in-process monitoring, and finished-product testing at every stage. Each rubber coated magnet batch undergoes Gaussmeter flux density measurement, pull-force verification on calibrated test rigs, rubber adhesion peel tests, salt-spray corrosion testing, and dimensional CMM inspection before shipment approval. This meticulous approach is why engineering firms, industrial distributors, and product designers worldwide rely on UPSUN as their long-term China rubber coated magnet manufacturer — we deliver the magnetic performance you specified, batch after batch, with full traceability documentation.
Why Choose UPSUN as Your China Rubber Coated Magnet Manufacturer?
Magnetic Circuit Design Expertise
We engineer high-performance neodymium magnetic assemblies with optimized alternating-pole arrangements and steel flux concentrators, maximizing the holding force of every rubber coated magnet while minimizing magnet material consumption — giving you the strongest grip at the lowest unit cost.
In-House R&D and Prototyping
Our magnetic engineers and mold designers collaborate on every custom rubber coated magnet project — from FEA magnetic simulation and 3D mold design through rapid prototype tooling and first-article inspection — reducing your development cycle from concept to production-ready sample in as few as 10 working days.
Advanced Molding & Magnetizing Equipment
UPSUN operates precision injection molding machines, hydraulic rubber compression presses, multi-pole pulse magnetizers, and automated assembly lines that produce rubber coated magnets in diameters from 16 mm to 88 mm with holding forces up to 350 kg — all within ±0.05 mm dimensional tolerances and ±3% pull-force consistency.
International Quality Certifications
Every rubber coated magnet order ships with full compliance to ISO 9001, SGS, RoHS, and REACH standards. We provide batch-specific test reports covering magnetic flux density, pull-force data, rubber Shore hardness, salt-spray hours, and dimensional inspection — so you receive verified, auditable quality on every delivery.
Strategic Logistics from Ningbo Port
Our factory sits within 30 minutes of Ningbo-Zhoushan Port, providing direct container access to major trade routes serving North America, Europe, Australia, and the Middle East. Standard orders ship via FedEx, DHL, UPS, or ocean freight with lead times of 7–25 days depending on your rubber coated magnet quantity, customization level, and destination.
Full-Spectrum Technical Consultation
Unsure which neodymium grade, rubber durometer, thread specification, or mounting configuration fits your application? Our bilingual engineering team provides free magnetic circuit analysis, material selection guidance, CAD drawing review, and sample evaluation — supporting you from initial concept through volume production of your custom rubber coated magnet design.
China Manufacturing Advantages for Rubber Coated Magnets
Partnering with a China-based rubber coated magnet manufacturer like UPSUN gives international buyers a decisive cost and supply-chain advantage. China controls approximately 90% of global rare-earth production and over 85% of sintered NdFeB magnet output — the core magnetic material inside every rubber coated magnet. This upstream dominance means UPSUN secures premium-grade neodymium magnet blanks at significantly lower raw material costs than any factory sourcing from outside China. When combined with our in-house steel machining, rubber compounding, and permanent magnet assembly capabilities, we deliver finished rubber coated magnets at 30%–50% lower cost compared to equivalent products manufactured in Europe or North America — without any compromise on magnetic performance, rubber quality, or dimensional accuracy.
Beyond pricing, UPSUN differentiates itself from other China rubber coated magnet manufacturers through data-driven quality control. We deploy inline Gaussmeter sorting stations, automated pull-force testers, and machine-vision rubber surface inspection systems that evaluate every single unit at production speed. Parts that fall outside specification are automatically rejected before they reach the packing line, maintaining an outgoing defect rate consistently below 0.2%. This systematic quality approach — combined with complete lot traceability from NdFeB powder batch to finished China Rubber Coated Magnet — is why global OEMs, industrial distributors, and branded product companies choose UPSUN as their preferred rubber coated magnet manufacturing partner.
