Quality Control

Before reprocessing the required size, the blank of neodymium magnet shall be tested for performance, and the blank with unqualified performance shall not be used. This is a key step for qualified magnets.

To quickly expose the defects and weak links of the product, test the moisture resistance of the product, to provide the basis for improving product quality.

To ensure a good electroplating appearance of the finished magnetic products, the magnet need to be cleaned before electroplating.

Deeply understand the surface and internal defects of materials, analyze the hardness and compressive strength of materials, and improve the processing technology.

In order to determine whether the magnet can meet the application requirements under special conditions, the corrosion resistance of the product shall be tested professionally.

In order to check whether the magnetic force meets the customer's requirements, random tests are carried out on the whole batch of orders.

Magnetic flux testing can not only measure the magnetic flux value, but also directly test the performance of magnetic products, so as to control the quality of magnets.

Measure the Gauss value of the center point of the magnetizing surface of the magnet, which is used to inspect the products requiring the Gauss value of the surface.
