We are the biggest manufacturer of SmCo magnets and our range covers most of the grades in the world. We boast a comprehensive array of SmCo magnetic materials of various grades and an annual output of approximately 1500 tons.
At NGYC, we possess state-of-the-art processing equipment and technology, enabling us to manufacture 1,500 tons of Samarium Cobalt magnets annually. With over three decades of exploration and continuous efforts, we have developed a unique production process that guarantees the production of high-quality magnet products. Our company boasts over 600 processing and precision machining equipment, capable of processing various complex shapes and high-precision Samarium Cobalt magnet products.
Our Equipment Includes:
Precise proportioning according to grade specifications
Key controls include vacuum pressure, voltage, argon filling capacity, refining time, and cooling temperature and time
Coarse, medium, and fine crushing with control over rotational speed, nitrogen pressure, oxygen content, and particle size
Main controls include mold dimensions, powder weight, temperature, humidity, pressure, and time
Key control points are vacuum pressure, argon pressure, sintering and aging temperatures, and duration
Inspection of external dimensions and observation of Max demagnetization curves
Main controls include dimensional tolerances, positional tolerances, and appearance
Inspection of appearance, dimensions, positional tolerances, and quantity
Comprehensive inspection of appearance, dimensions (full or sampling), positional tolerances (full or sampling), and magnetic performance (full or sampling) as per requirements
Custom or standard packaging, quantity verification, boxing, and testing reports
Depending on customer requirements, we employ laser cutting, shearing, bending, high-precision wire cutting, stamping, and laser welding processes. Surface treatments such as leveling, sandblasting, polishing, and plating are applied when necessary. Key controls in machining include dimensional tolerances, positional tolerances, appearance, and part identification/marking.
Rigorous inspections are conducted during the manufacturing process, encompassing visual inspection, dimensional measurements, positional tolerance checks, trial assembly, and quantity counting.
Thorough cleaning is performed using ultrasonic technology, ensuring the pristine condition of the components. Visual inspection and quantity counting are also carried out.
The annealing process is precisely controlled, considering hydrogen gas flow rate, temperature, and time.
The final products undergo comprehensive inspections, including visual examination, dimensional measurements, positional tolerance checks, assembly (if required), magnetic performance testing, and quantity counting.
Custom or standard packaging, quantity verification, boxing, testing reports, and delivery manifests
At NGYC, we prioritize quality in every aspect of our production process. With our state-of-the-art testing equipment and stringent quality management systems, we ensure the delivery of superior products that exceed customer expectations.
Equipped with high-precision magnetic field cameras, magnet performance analyzers at various temperatures, particle analyzers from Germany, 2D imaging measurement devices, coordinate measuring machines (CMM), roughness testers, coating thickness gauges from America, cylindricity gauges from Japan, laser micrometers, laser height gauges, Keyence's one-click imaging systems, and magnetic inclination angle detectors, our advanced testing equipment provides robust assurance for producing top-quality products. Additionally, our investment in automated inspection devices minimizes the chances of human error, further enhancing product quality.
We operate under the ISO 9001:2015 and IATF 16949:2016 quality management systems, adhering to VDA6.3 standards for comprehensive monitoring, detection, prevention, and timely correction of potential failure modes throughout the entire production process. We conduct inspections for every step of the manufacturing process to prevent the flow of non-conforming products to subsequent stages. Prior to shipment, we conduct either full inspections or random sampling inspections of dimensions and magnetic performance according to customer requirements. Our quality control measures have demonstrated long-term reliability and repeatability.
Thanks to our scientific management practices and strict adherence to product quality, NGYC has been recognized as an Enterprise for Export Product Quality Assurance and a Prestigious Brand in the city of Ningbo.
