COCOMAG PRODUCTION
Sintered Ndfeb permanent magnet is produced by powder metallurgy. From material preparation to finished product delivery, it
generally goes through more than a dozen process links, including several detection and analysis in different stages.The whole
production process is a system engineering, linked together. Generally, production of ndfeb is a big, complicatedand interlocking
system.The process of producing the blank of the magnet is called the “pre-production”, and the process of processing the blank
into the final product is called the “post-processing”. Magnetic material manufacturers are mainly divided into two categories,
one is the manufacturers that have both the “Pre” and “Post”processing, and the other is the processing manufacturers that focus
on the “post process”.
