ndfeb magnets are also known as modern industrial MSG. As an important additive in modern industry, high-performance magnets promote the advancement of the contemporary industry and are widely used in various fields. The quality of finished magnets is mainly reflected in the following three Aspect: magnet performance; magnet size; magnet plating.

First, the performance of the magnet

The performance guarantee of NdFeB rough material is the initial and most basic prerequisite.

1. Magnet blank manufacturers prepare different grades of NdFeB materials according to business needs.

2. The advanced nature of the magnet production process also determines the performance quality of the magnet.

3. Quality monitoring in each process of sintering is also very important.

Second, the shape and tolerance of the magnet shape

Various shapes of neodymium iron boron magnets, such as circular, cylindrical, profiled, square, tile-shaped, trapezoidal. Different shapes of magnets are machined by different machine tools. The skilled technology and high-precision processing equipment also determine the accuracy of the product. Third, the surface coating of the magnet

The plating of the magnet plating includes zinc, nickel, nickel copper nickel, electroplated copper and gold, silver, and the like. Jiada Magnet has its own electroplating workshop, which can electrolyze the magnet according to different needs of customers.

The quality of NdFeB Magnets is simply to control the performance of the raw materials, control the dimensional tolerances during processing, grasp the time during the plating process, and confirm the coating thickness after plating. Test the magnetic flux and magnetic Gauss value of the magnet; measure the dimensional accuracy with a vernier caliper and a micrometer; color and brightness of the coating, coating and adhesion of the coating, and observe the surface of the magnet by appearance, with or without spots, There is no falling edge to evaluate the overall quality of the magnet.

We have a complete testing process, advanced testing equipment at home and abroad, careful process control to ensure the quality of magnets, and provide a stable product foundation for customer development.
