CJL: Opening a New Era of High-Efficiency Industrial Equipment with Customized Permanent Magnet Assemblies
Permanent Magnet Technology — Introduction to CJL
Hangzhou Magnet Power Technology Co., Ltd.(CJL) was founded by a group of magnetic-materials experts from the Chinese Academy of Sciences. It is a high-tech enterprise focusing on the R&D, production, and service of customized permanent magnet assemblies. The company has a core team consisting of 3 PhDs, 3 master’s degree holders, and 1 national “Distinguished Young Scholar” permanent magnet expert. It holds more than 20 invention patents in rare-earth permanent magnet materials and has passed authoritative certifications such as ISO9001 and IATF16949. Relying on internationally advanced powder-metallurgy forming equipment, vacuum sintering equipment, and unique processes, it can customize and produce various permanent magnet assemblies such as samarium-cobalt and neodymium-iron-boron for different fields including automobiles, aerospace, chemical engineering, and medical care. It can handle everything from special-shaped design and performance adjustment (such as high-temperature and high maximum energy product) to precise control of very small or large sizes. It not only increases power and endurance for new energy vehicle drive motors and reduces energy consumption for fan motors in chemical enterprises, but also provides one-stop services from early-stage selection consultation to production progress feedback, after-sales fault resolution, and regular return visits. This provides solid technical support for meeting customers’ customization needs and also enables CJL to stand out in a highly competitive market.
Customization: The Key to Meeting Market Demand
In the industrial field, the operating environments and working requirements of different equipment vary greatly, which determines that the demand for permanent magnet assemblies is highly diversified. CJL has deeply recognized this industry pain point and takes customization services as one of the company’s core competitive advantages. Whether it is shape and performance, or size and specifications, CJL can tailor the most suitable permanent magnet assembly according to customers’ specific needs.
In terms of shape design, CJL breaks through the shape limitations of traditional permanent magnet assemblies and can produce products with various complex shapes. For example, for some special motor structures, permanent magnets need to have unique curvature or special-shaped contours. Through innovative mold design and advanced manufacturing processes, CJL’s R&D team has successfully achieved high-precision production of special-shaped permanent magnets, ensuring that they can be perfectly embedded inside the motor, effectively improving the uniformity of the motor’s magnetic field distribution, thereby improving the motor’s operating efficiency and stability. This precise customization of shape not only meets the unique structural needs of the equipment, but also provides possibilities for miniaturized and lightweight equipment design, helping customers achieve more powerful functions in limited space.
In terms of performance customization, CJL also demonstrates strong technical strength. Different industrial equipment operates under different working conditions, and the requirements for the magnetic performance of permanent magnet assemblies also vary. Some equipment needs to maintain stable magnetism in high-temperature environments, while others have extremely high requirements for magnetic field strength and uniformity. With deep accumulation in permanent magnet material R&D, by adjusting material formulas and optimizing production processes, CJL can precisely control magnetic performance parameters of permanent magnet assemblies, such as remanence, coercivity, and maximum energy product, providing customers with permanent magnet assemblies that meet specific performance requirements.
In addition to shape and performance, CJL can also handle customization of size specifications. Whether it is a small-sized precision permanent magnet assembly used for micro electronic equipment or medical devices, or a large-sized permanent magnet assembly used for industrial heavy machinery or wind power generation equipment, CJL can produce strictly within the tolerance range required by customers to ensure the dimensional accuracy and consistency of the product. This all-round customization service enables CJL’s permanent magnet assemblies to be widely used in automobiles, electronic products, industry, aerospace, and other fields, providing feasible solutions for customers in different industries, helping them improve product performance and enhance market competitiveness.
Technology and Processes Create Excellent Quality
The reason why CJL can achieve remarkable results in the field of customized permanent magnet assemblies is inseparable from its strong technical strength and advanced production processes. The company has an R&D team composed of multi-disciplinary professionals such as permanent magnet material experts, motor engineers, mechanical designers, and electronic engineers. With “innovation, unity, professionalism, and integrity” as its concept, it continuously explores new technologies, new methods, and new processes, and is committed to providing high-performance and high-quality permanent magnet product solutions for various industries.
In terms of production equipment, CJL has introduced a series of internationally advanced magnetic-material production equipment, covering all links from raw material processing to finished product manufacturing. This equipment not only has the characteristics of high precision and high efficiency, but can also effectively ensure product consistency and stability. For example, in the forming process of permanent magnets, the company uses advanced powder-metallurgy forming equipment, which can accurately control the density and microstructure of permanent magnets, thereby improving their magnetic performance; in the sintering process, the company introduces a vacuum sintering furnace, and by precisely controlling sintering temperature and time, it further optimizes the crystal structure of the permanent magnets and improves their comprehensive performance.
Advanced production processes are also a strong guarantee of product quality. The company has unique processes in the production technology of high-performance samarium-cobalt, high-performance neodymium-iron-boron, and magnetic device products. Taking samarium-cobalt permanent magnet production as an example, through precise adjustment of raw material formulas and strict control of a series of processes such as melting, powder preparation, forming, and sintering, the produced samarium-cobalt permanent magnets have excellent properties such as high remanence, high coercivity, and high temperature stability, and can meet the needs of fields with extremely demanding requirements for permanent magnet performance, such as aerospace and high-end medical equipment.
Strict control of product quality runs through the entire production process. Starting from raw material procurement, the company has established a strict supplier screening mechanism to ensure that each batch of raw materials meets high quality standards. In the production process, multiple quality inspection procedures are set up, and advanced testing equipment and technology are used to conduct comprehensive inspections of magnetic performance, dimensional accuracy, surface quality, and other aspects. For example, professional magnetic performance testers are used to accurately measure parameters such as magnetic flux and magnetic field strength of permanent magnet assemblies; high-precision coordinate measuring machines are used to strictly control product dimensional accuracy to ensure that dimensional tolerances are controlled within a very small range; surface roughness measuring instruments and appearance inspection equipment are used to carefully inspect surface quality to prevent surface defects.
Technical strength is reflected not only in production and quality control, but also in patents and certifications. Up to now, CJL has obtained more than 20 invention patents for rare-earth permanent magnet materials. These patented technologies are the crystallization of the company’s innovation capability and also an important advantage in market competition. At the same time, the company has passed multiple international authoritative certifications such as ISO9001 quality management system certification and IATF16949 automotive industry quality management system certification. This fully proves that the company has reached an internationally advanced level in quality management and production process control and has laid a solid foundation for its products to enter high-end markets at home and abroad.
