Magnetization of NdFeB plastic magnet


Magnetic circuit simulation and measurement of NdFeB plastic magnet


Surface treatment of NdFeB plastic magnet

Technology name	Introduction	Applicable scope	Feature
Electrophoretic Coating	The most commonly used technique in industry.	Applicability to most compression magnets.	Salt spray test: 48Hrs;                 Steady temperature damp test: 240Hrs Excellent oil resistance and solvent resistance; Smooth surface.
Spray Coating	Spray the epoxy anti-corrosion paint to compression magnet's surface.	Apply to small sized work pieces, especially for arc-compression magnets.	High-effeciency & Good consistency & High passing rate;  Salt spray test: 24Hrs;                   Steady temperature damp test: 240Hrs.
Anti-rust Oil Dipping	Anti-rust film can greatly improve compression magnet's anti-rust capability.	Especially suitable for small inner-diameter's compression magnet.	High-effeciency; Simple process; No dimension change.
Infiltration	Infiltrate anaerobic adhesive  into compression magnet's voids by negative pressure.	Apply to extreme environment, such as oil or solvent.	Seal magnet's voids; Improve strength; Make it possible to work under oil or solvent for a long time.
