How To Control The Quality Of Ring Neodymium Magnet?

Jun. 13, 2019

First, the magnetic properties

First, the key to the decision is to control the magnetic properties of the raw materials in the production process.

1. Raw material producers sinter NdFeB according to business needs or medium or low grade. The company only sells high-grade NdFeB in the national standard for raw materials purchased.

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

3. Quality monitoring during production is very important.

Second, the shape and tolerance of the magnet

Various shapes of neodymium iron boron magnets, such as circular, shaped, square, tile-shaped, trapezoidal. Different sizes of materials are machined from different machine tools to cut rough materials. Advanced technology and machine operators determine the accuracy of the product.

Third, the surface coating treatment

The plating quality of the surface plating, zinc, nickel, nickel, copper and nickel plating copper and gold plating process. The Genuine Neodymium Magnet can be electroplated as required by the customer. The short and good summary of the quality of NdFeB products is to grasp the performance, control the dimensional tolerance, and judge the appearance and evaluation of the coating. Detecting the Gaussian surface of the magnetic flux of the magnet, etc.; dimensional tolerance, the accuracy of the caliper measurement; the color and brightness of the coating, the adhesion of the coating, and the appearance of the surface of the magnet through the appearance, with or without spots, with or without Drop the corners to assess the quality of the product.
