We carry a limited number of standard parts because precise specifications usually vary from one customer to another, requiring bespoke items to be manufactured. For prototyping, we can grind standard blocks into an arc segment using specially profiled grinding wheels, a few of which are shown in the slideshow below. When full scale production is required, the magnet is pressed to shape in a tool, prior to the sintering process as this is more efficient and cost effective than grinding from blocks.
2) The coating of NdFeB magnets can be Zn, Ni, Ni-Cu-Ni, Epoxy, CR3+ZN, NI+AG, NI+AU.
3) Our factory can also manufacture various sizes of NdFeB magnet, according to the customer's specification
