China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Sintered ferrite magnet is a widely used in modern industry, a magnetic material, in the field of electronics, electrical appliances, speakers, toys, motors, sensors and other areas with a very large number of, in the production process, whether it is necessary to open the mold is a common problem, the following xiaofu for you to introduce the following.
The production of sintered ferrite magnets usually does require molding. This is because ferrite magnets are mostly manufactured through the powder metallurgy process, which involves mixing and pressing ferrite powders into specific shapes and then sintering them at high temperatures to form hard, dense magnets. In order to get the exact size and shape, molds are used to ensure that the pressed product meets the design requirements.

Especially for non-standard sizes or special shapes of ferrite magnets, custom molds are necessary to meet the specific application requirements. For some commonly used, standard size magnets, such as round, ring, tile, etc., the manufacturer may already have ready-made molds, so for these products, the customer usually does not need to bear the cost of mold opening.
In summary, the need for a mold depends on whether or not there is an existing mold available for the size and shape of the magnet needed, as well as the specific needs of the customer. For mass production, although the initial opening of the mold will increase the cost, as the production volume increases, the cost of the molds for individual products will be spread out, making the overall cost more economical.
When you buy magnets magnet suppliers need to let you out of the open magnet mold costs, you can find a few more magnet manufacturers to ask, may be able to save this cost.
