How To Control The Product Quality Of NdFeB Magnets

NdFeB magnet is also called modern industrial monosodium glutamate. As an important high-performance magnetic material for modern industry, it promotes the progress of contemporary crafts and society and is widely used in various fields. So, how to control the product quality of NdFeB magnets?

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

1. Raw material manufacturers only sell high-grade NdFeB according to business needs or the national standards for purchasing raw materials for mid-grade or low-grade sintered NdFeB.

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

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

2. Magnet shape, size and tolerance value Use various shapes of NdFeB magnets, such as round, special-shaped, square, tile-shaped, trapezoidal. Different size materials are processed by different machine tools to cut rough materials. Advanced technology and machine operators determine the accuracy of the product.

3. Surface coating treatment The coating quality of the surface coating, zinc, nickel, nickel-copper-nickel electroplating copper and gold electroplating processes. Plating options can be done on the product according to customer requirements.

A brief summary of the quality of NdFeB products is to grasp the performance, dimensional tolerance control, and judge the appearance inspection and evaluation of the coating. Detect the Gaussian surface of the magnetic flux of the magnet, and other tests; dimensional tolerance, the accuracy that can be measured with a vernier caliper; coating, the color and brightness of the coating and the bonding force of the coating, and the surface of the magnet can be observed by appearance. Drop edges and corners to evaluate the quality of the product.
