Machining & Tolerance
Generally, switch neodymium magnets must be machined with diamond-grinding techniques. Sometimes, machining operations may be performed on switch magnet materials with carbide tools, but surface finishes for NdFeB magnet switch are not good enough. Standard tolerances for NdFeB magnets are +/- 0.1 mm, but stricter tolerances are required in specific applications.

Surface Treatments
Corrosion resistance of switch neodymium magnets is not strong. Therefore, surface coating or plating is needed for NdFeB switch magnets. All kinds of surface coating are available, like nickel, zinc, Ni-Cu-Ni, gold, silver, stannum, chrome, etc. We also applied special surface protection to NdFeB magnets, like ABS coating (acrylonitrile butadiene styrene copolymers), rubber coating, PTFE (Telfon) coating, stainless steel case, etc.

We package cargoes in standard specification. It can prevent switch neodymium magnets from being broken because of vibration in shipment. During delivery, switch magnets should be placed in dry environment.

Changzhou Magnetic Device Factory is specialized in production of permanent magnet and permanent magnet assemblies. As the strongest type of permanent magnet made so far, NdFeB magnets are widely used in various applications, such as relay neodymium magnet, sensor magnet, switch neodymium magnet, etc. Our products are exported to many countries and area, including American, Japan, Hong Kong, Southeast Asia, etc.
