3. Manufacturing and Quality Control in Export - Oriented Rare Earth Permanent Magnet Enterprises

3.1 Advanced Manufacturing Processes

3.1.1 Sintered Magnet Manufacturing

Most export oriented rare earth permanent magnet enterprises, such as Jiangxi Jinli Permanent Magnet and Zhongke Sanhuan, use advanced sintered magnet manufacturing processes. The process begins with the careful selection of high - purity raw materials. Rare earth metals like neodymium, dysprosium, and terbium, along with iron and other alloying elements, are sourced from reliable suppliers. These raw materials are melted in a vacuum induction furnace or an arc - melting furnace under precisely controlled temperature and atmosphere conditions. This ensures homogeneous mixing of the elements and prevents oxidation, which could significantly affect the magnetic properties of the final product.

After melting, the alloy is cast into ingots. These ingots are then subjected to hydrogen decrepitation. In this process, the ingots are exposed to hydrogen gas at specific temperature and pressure conditions. Hydrogen diffuses into the alloy, causing it to crack and break into small pieces. This is a crucial step as it reduces the size of the alloy particles, which is beneficial for subsequent processing. The hydrogen - decrepitated alloy particles are then milled into a fine powder. The milling process is carried out in a controlled environment to prevent oxidation and contamination. Smaller particle sizes are generally preferred as they can lead to better magnetic properties in the final magnet.

Once the powder is prepared, it is compacted into the desired shape under high pressure. This can be done through die - pressing or isostatic pressing. Die - pressing is suitable for producing magnets with simple shapes, while isostatic pressing is more versatile and can be used to create complex geometries. During compaction, the powder particles are forced together, forming a "green compact" with a certain shape and density.

 3.1.2 Bonded Magnet Manufacturing

For some export - oriented enterprises that produce bonded rare earth permanent magnets, the manufacturing process has its own unique characteristics. The process starts with the preparation of the magnetic powder, which is similar to that of sintered magnets but may have different particle size requirements. The magnetic powder is then mixed with a binder material. The binder can be a thermoplastic polymer (such as nylon or polypropylene), a thermosetting resin (like epoxy), or an elastomer. The mixing process is crucial to ensure a uniform distribution of the magnetic powder in the binder.

Once mixed, the composite material is molded into the desired shape using techniques such as injection molding, compression molding, or extrusion. Injection molding is a popular choice as it allows for the production of complex - shaped parts with high precision and efficiency. In injection molding, the mixture is heated to a molten state and injected into a mold cavity under high pressure, where it solidifies to form the magnet. After molding, the bonded magnets may undergo finishing operations such as trimming, deburring, and surface treatment. These operations are carried out to improve the appearance and dimensional accuracy of the magnets and to enhance their performance in specific applications.

 3.2 Stringent Quality Control Systems

 3.2.1 In - process Quality Monitoring

Export - oriented rare earth permanent magnet enterprises place great emphasis on in - process quality monitoring. At each stage of the manufacturing process, strict quality control measures are implemented. For example, during the raw material inspection, advanced analytical techniques such as X - ray fluorescence spectroscopy are used to determine the purity and composition of the rare earth metals and other alloying elements. This ensures that only high - quality raw materials are used in the production process.

During the melting and casting process, sensors are used to monitor the temperature, pressure, and other parameters in real - time. Any deviation from the set values can be quickly detected and corrected. In the milling and compaction stages, the particle size distribution of the powder and the density of the green compact are carefully measured. High - precision instruments such as laser diffraction particle size analyzers and density meters are used for these measurements.

 3.2.2 Final Product Testing

Before the products are shipped for export, they undergo a series of comprehensive final product tests. Magnetic property testing is one of the most important aspects. Instruments such as vibrating sample magnetometers (VSM) and hysteresisgraphs are used to measure the magnetic properties of the magnets, including remanence, coercivity, and energy product. These properties are crucial for the performance of the magnets in various applications, and any deviation from the specified values can render the magnets unsuitable for their intended use.

In addition to magnetic property testing, the products are also tested for dimensional accuracy, surface finish, and corrosion resistance. Dimensional accuracy is measured using precision measuring tools such as coordinate measuring machines (CMM). The surface finish of the magnets is evaluated using techniques such as optical microscopy and profilometry. To test the corrosion resistance, the magnets are subjected to accelerated corrosion tests, such as salt - spray testing, where they are exposed to a salt - water mist environment for a specific period of time. The appearance and performance of the magnets after the test are then evaluated to determine their corrosion resistance.
