So today we're going to talk about whether magnets are magnetic before they're processed.
Answer: Magnets are not magnetic before processing, so the question comes, how is magnetic? Today we 'll talk about how magnetism is added.
The raw material of neodymium iron boron powerful magnet is made by: mineral raw material -- ratio -- smelting -- pressing molding -- sintering. Become a raw material for neodymium iron boron
Subsequent processing is: neodymium iron boron raw material -- abrasive -- slice -- cooking sheet -- electroplating -- magnetic filling -- packaging -- shipping.
I believe you have seen that magnetic filling is the last step. It is filled with magnetic charging machines. The raw material of neodymium iron boron is composed of various mineral molecules. The magnetic charging machine is to activate the molecules inside the material, resulting in magnetic expansion. Magnetism comes out.
