Irregularly shaped magnets are not actually a single piece; they are made from raw materials such as neodymium, iron, and boron, which are crushed, mixed, and sintered together. This is how our magnet raw materials are produced.
Irregularly shaped magnets are small in size but powerful, capable of attracting objects 500 times their own weight. Magnetic attraction and induction functions are being increasingly applied in various industries and products.
The raw materials for irregularly shaped magnets are mainly of two types: round and square. The required dimensions are cut from large blanks using a slicing machine. After cutting, the magnets undergo surface treatment, specifically electroplating. Electroplating protects the magnets from corrosion and rust and has no effect on their magnetic properties.
The surface treatment of magnets involves electroplating. Common plating options include zinc plating, nickel plating, and nickel-copper-nickel plating. More expensive options include gold plating and black epoxy coating.
After electroplating, the magnets are still not magnetic. They need to be magnetized using a magnetizing machine. After magnetization, they become the powerful magnets we see.
Next is the processing of the magnets. Simple square and round magnets have relatively low processing costs due to the uncomplicated process. However, if there are holes in the middle or if the shape is irregular, or if high precision is required, these factors will affect the price of the magnet.
In terms of dimensions, check the tolerances of the required dimensions. Some outer diameters and thicknesses may have significant negative tolerances. Regarding the surface treatment, if the surface color is poor, or if there are chips or cracks, caution is needed. Also, if there are many small chips or cracks on the surface, this should also be a cause for concern.
