China Ferrite Rubber Magnet Manufacturer — Flexible Ferrite Magnetic Solutions by UPSUN
Our Ferrite Rubber Magnet Products
As a professional China Ferrite Rubber Magnet Manufacturer, UPSUN produces high-quality flexible magnetic materials by compounding strontium ferrite powder (SrO·6Fe₂O₃) with synthetic rubber and thermoplastic polymer binders through advanced calendering and extrusion processes. Our ferrite rubber magnets are available in isotropic and anisotropic grades — including Y8T, Y10T, Y20, Y25, Y30, C5, and C8 — and can be supplied as continuous rolls, pre-cut sheets, die-cut shapes, or extruded strips and profiles. Each ferrite rubber magnet we manufacture delivers stable magnetic performance across a wide operating temperature range of −40 °C to +100 °C, with energy products up to 1.6 MGOe for anisotropic grades, making them the most cost-effective permanent magnet material for applications that require flexibility, lightweight construction, and easy fabrication.
Unlike rigid sintered ferrite ceramic magnets that are brittle and prone to chipping, UPSUN ferrite rubber magnets combine the magnetic properties of hard ferrite with the mechanical flexibility of rubber — resulting in a material that can be bent, twisted, rolled, punched, die-cut, laminated, and adhesive-backed without any loss of magnetization. The inherent elasticity of the rubber binder also delivers a high coefficient of friction, providing natural slip resistance when ferrite rubber magnets are placed against steel or painted metal surfaces. From printable magnetic sheeting for vehicle signs and promotional fridge magnets to precision-extruded magnetic gasket strips for refrigerator doors and multi-pole ferrite rubber rings for sensor applications, UPSUN is the China ferrite rubber magnet manufacturer that global buyers trust for consistent quality, competitive pricing, and dependable supply.
About UPSUN — Your Dedicated Ferrite Rubber Magnet Supplier in China
Ningbo Upsun Magnetic Technology Co., Ltd. is based in Ningbo, one of China's most strategically important port cities and a long-established hub for ferrite and rare-earth magnetic material production. With over a decade of hands-on expertise in permanent magnet manufacturing — spanning sintered ferrite, bonded ferrite, NdFeB, and ferrite rubber magnets — UPSUN serves OEM, ODM, and distribution partners in more than 30 countries. Our dedicated ferrite rubber magnet production facility features complete in-house capabilities: ferrite powder blending and compounding, twin-screw extrusion, multi-roll calendering, through-thickness and multi-pole magnetization, PVC and adhesive lamination, precision slitting, and die-cutting — all integrated under one roof to ensure full process control from raw material to finished product.
UPSUN operates under a certified ISO 9001 quality management system with a "zero-defect" production philosophy. Every batch of ferrite rubber magnets is tested in our in-house laboratory for Gauss value uniformity, magnetic energy product (BHmax), dimensional accuracy, adhesive peel strength, rubber tensile elongation, and accelerated UV and humidity aging performance. This systematic quality assurance process guarantees that each ferrite rubber magnet shipment meets the exacting standards required by international buyers — whether you are sourcing flexible magnetic sheets for the signage industry, extruded magnetic strips for white goods OEMs, or injection-molded ferrite rubber components for automotive sensor manufacturers. As a China ferrite rubber magnet manufacturer with full vertical integration, UPSUN delivers the quality, consistency, and pricing that make long-term partnerships work.
Why Choose UPSUN as Your China Ferrite Rubber Magnet Manufacturer?
Ferrite Rubber Magnet Formulation Expertise
We develop and control our own ferrite-rubber compound formulations, precisely adjusting the ratio of strontium ferrite powder, rubber binder, and processing additives to optimize the balance between magnetic strength, flexibility, and mechanical durability for high-performance magnetic applications — whether your project requires maximum energy product or maximum bend radius.
Experienced R&D and Engineering Team
Our material scientists, magnetic engineers, and process technicians work together on every ferrite rubber magnet project — from initial grade selection and magnetization pattern design through extrusion die engineering and production line optimization — ensuring that your custom ferrite rubber magnet delivers peak performance at target cost.
Full-Scale Production Equipment
UPSUN operates high-capacity twin-screw compounding extruders, precision multi-roll calenders, continuous through-thickness and multi-pole magnetizers, inline PVC and adhesive laminators, and automated slitting and die-cutting lines capable of producing ferrite rubber magnets in thicknesses from 0.3 mm to 25 mm and widths up to 620 mm — at volumes from sample quantities to full container loads.
Certified International Quality Standards
Every ferrite rubber magnet order is produced under our ISO 9001 quality system and verified against SGS, RoHS, and REACH requirements. We provide detailed test certificates with each shipment — including Gauss uniformity maps, BHmax values, dimensional inspection data, and adhesive peel test results — giving your incoming QC team full traceability and confidence.
Direct Port Access from Ningbo
Located less than 30 minutes from Ningbo-Zhoushan Port — the world's busiest cargo port — UPSUN offers fast, cost-efficient shipping to North America, Europe, Southeast Asia, the Middle East, and Oceania. Standard ferrite rubber magnet orders ship via FedEx, DHL, UPS, or ocean freight with lead times of 7–21 days depending on volume and customization scope.
Complete Technical Consultation
Not sure whether an isotropic or anisotropic ferrite rubber magnet is right for your application, or which magnetization pattern — through-thickness, multi-pole, or single-side — will deliver the best holding force for your design? Our bilingual technical team provides free material consultation, magnetic simulation support, and sample evaluation to help you make the optimal engineering decision.
China Manufacturing Advantages for Ferrite Rubber Magnets
China is the world's dominant producer of ferrite magnetic powder — the core raw material in every ferrite rubber magnet — accounting for over 80% of global hard ferrite output. By manufacturing in Ningbo, UPSUN taps directly into this upstream supply chain, sourcing premium strontium ferrite powder from established domestic refineries at substantially lower cost than factories in Europe, North America, or Southeast Asia. When combined with China's mature rubber compounding infrastructure, skilled manufacturing workforce, and decades of accumulated ferrite rubber magnet production experience in the Yangtze River Delta region, UPSUN delivers finished permanent magnet products at 30%–50% lower total cost compared to equivalent overseas manufacturers — all while meeting identical performance specifications required by international OEMs.
Quality assurance is where UPSUN sets itself apart from other China ferrite rubber magnet manufacturers. Our production lines are equipped with inline Gaussmeter scanning stations that measure magnetic flux density across the full width of every sheet and strip in real time, plus automated dimensional gauging and surface defect detection systems. Any material that deviates from the customer-approved specification is automatically diverted before it reaches the slitting or die-cutting stage, maintaining a finished-product defect rate consistently below 0.3%. This inline quality architecture — combined with end-to-end lot traceability from ferrite powder batch number to final China Ferrite Rubber Magnet packing list — is why demanding global brands, industrial distributors, and appliance OEMs trust UPSUN as their long-term ferrite rubber magnet supply partner.
