--- Why Choose Dongguan Zhenglong Magnet Co., Ltd.? ---
• Extensive Range of Customized Magnetic Solutions:
Dongguan Zhenglong Magnet Co., Ltd. has built a strong reputation by delivering highly customized magnetic solutions tailored to diverse industrial needs. A prime example is our collaboration with a mid-sized automotive electronics manufacturer in Germany, who required high-temperature resistant NdFeB magnets for use in engine sensor assemblies operating at sustained temperatures above 150°C. The client initially struggled with magnet demagnetization and dimensional instability under thermal stress. We stepped in with our N45SH and N48UH grade high-temperature NdFeB magnets, processed into precision trapezoidal shapes with countersunk holes for secure mounting. Our engineering team worked closely with the client to optimize the magnet’s geometry and surface treatment—applying nickel-copper-nickel plating to enhance corrosion resistance. After three months of rigorous testing, the client reported zero failures in field trials. This success not only secured a long-term contract worth over €1.2 million annually but also highlighted our ability to solve complex technical challenges through deep customization. Beyond automotive applications, we’ve delivered custom rubber magnets for a premium leather handbag brand in Italy, where flexibility and aesthetic appeal were critical. Our ability to produce thin, bendable magnets with precise magnetic gradients enabled seamless integration into the bag’s closure system without compromising design. These real-world cases underscore our core strength: turning complex customer demands into reliable, high-performance magnetic components.
• Commitment to Quality and Compliance:
Quality and compliance are at the heart of every product we deliver. A notable case involved a U.S.-based LED display manufacturer that faced recurring issues with magnetic fasteners detaching during installation due to weak adhesion and poor temperature stability. After analyzing their application, we recommended our ferrite magnets with enhanced bonding layers and introduced a new batch of rubber magnets with integrated adhesive backing. All products were manufactured under strict ISO9001 and ISO14001 standards, ensuring consistent performance across batches. To validate compliance, we provided full certification packages including CCC, CSA, and third-party test reports from SGS. The client was impressed by our transparency and traceability—each shipment came with a QR code linking to detailed production logs, material certifications, and QC inspection results. Within six months, the client reduced return rates by 92% and increased production efficiency by 30%. This project exemplifies our commitment to not just meeting but exceeding international standards. Additionally, our factory’s 11–20-person QC team conducts multi-stage inspections—from raw rare earth material analysis to final magnetic flux testing—ensuring a finished product qualification rate of over 98%. Even during peak season lead times (6–12 months), we maintain this level of consistency, proving that scale and quality are not mutually exclusive. Our certifications, including ISO17799 for information security and ISO22000 (for supply chain integrity), further reinforce trust, especially for clients in regulated industries like medical devices and aerospace. These real-world validations have made Zhenglong a preferred supplier for over 200 global clients, including Fortune 500 companies.

• High-Temperature Resistant NdFeB Magnets:
Our high-temperature resistant NdFeB magnets are engineered for extreme environments where standard magnets fail. One standout case involves a renewable energy startup in Canada developing compact lithium-ion battery packs for electric vehicles. The challenge: magnets used in the battery’s internal fastening system would degrade during charging cycles, which generated localized heat up to 180°C. Traditional N42 magnets lost over 40% of their magnetic strength after just 500 cycles. We proposed our N45UH and N50EH-grade magnets, tested to retain over 90% of their magnetic flux at 180°C, with a maximum energy product (BH)max reaching 44 MGOe. We also added epoxy resin coating to prevent oxidation and mechanical wear. After six months of real-world testing in harsh winter conditions, the client confirmed zero degradation and improved safety margins. This solution became a key differentiator in their product launch, earning them a $3.5 million investment round. Another success story comes from an industrial equipment manufacturer in Poland, which needed magnetic clamps for drying ovens operating at 150°C. We supplied custom N40SH magnets in T-shaped profiles with precision-ground edges, enabling stable fixation even under vibration and thermal cycling. These magnets not only met but exceeded the client’s durability expectations, reducing maintenance costs by 60%. Our ability to offer performance grades from M to EH, combined with flexible shaping (including arc, stepped, and conical forms), ensures we can meet even the most demanding specifications. Whether it's for motors, sensors, or precision instruments, our high-temp NdFeB magnets deliver unmatched reliability and longevity.

• Easy Ordering Process and Quick Delivery:
Our streamlined ordering process and rapid delivery capabilities have transformed the way businesses source magnets. Take the case of a toy manufacturer in Mexico that needed 10,000 custom irregular-shaped neodymium magnets for a new line of magnetic building blocks. They required small-batch customization (only 500 units per design) with tight deadlines. We accepted the order within 24 hours, provided free samples via DHL within 7 days, and began mass production on our five dedicated lines. Despite being in peak season, we delivered the first batch in just 45 days—well ahead of the client’s 90-day target. The client praised our agility, noting that our digital order tracking system allowed real-time visibility into raw material procurement, production progress, and shipping status. For urgent sample requests, we’ve achieved delivery in as little as 7–15 days thanks to our flexible scheduling and in-house processing capacity. On the payment side, we support PayPal and other secure methods, making international transactions smooth and safe. Our logistics partners—including SF Express, Debon Logistics, DHL, and FedEx—ensure damage-free delivery with full insurance coverage. In another instance, a European client experienced a supply disruption and needed emergency replacement magnets. We expedited their order, shipped via FedEx with priority handling, and resolved the issue within 10 days. This responsiveness, backed by our annual sales volume of $50–100 million USD and robust procurement network ($2.5–5 million USD in annual purchases), ensures we can scale quickly without compromising quality. By combining technology, efficiency, and customer-centric service, we make sourcing high-performance magnets faster, easier, and more reliable than ever before.
