How To Judge the Quality of Ring Neodymium Magnets

Dec. 02, 2020


Magnetic properties


First of all, the key to the decision is to control the magnetic properties of the Neodymium Magnet during the production process.


1. According to the business needs of the raw material manufacturer, medium or low grade NdFeB. The company only sells high-grade NdFeB according to the national standards of the raw materials purchased.


2. The advanced nature of the production process also determines the performance and quality of the Ring Neodymium Magnet.


3. Quality control in the production process is very important.

The shape and tolerance of the magnet


Various shapes of Neodymium Iron Boron Magnets, such as round, irregular, square, tile, trapezoidal. Process materials of different sizes from different machine tools to cut rough materials. Advanced technology and machine operators determine the accuracy of the product.


Surface coating treatment


The coating quality of the surface coating includes zinc, nickel, nickel, copper and nickel coating, copper and gold coating process. Neodymium magnets can be electroplated by customers as required. A brief summary of the quality of NdFeB products is to grasp the performance, control the dimensional tolerance, judge the appearance of the coating and evaluate it. Gaussian surface for detecting magnetic flux of magnets, etc.; dimensional tolerances, caliper measurement accuracy; color and brightness of the coating, adhesion of the coating, and appearance of the magnet surface are all corners to evaluate the quality of the product.
