Magnetization of NdFeB bonded magnet
14 Years Experienced High Solvent Resistance Plastic Bonded Magnet


Surface treatment of NdFeB bonded magnet

Technology name

Introduction

Applicable scope

Feature

Electrophoretic Coating

The most commonly used technique in industry.

Applicability to most compression magnets.

  1. Salt spray test: 48Hrs;                 Steady temperature damp test: 240Hrs
  2. Excellent oil resistance and solvent resistance;
  3. 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.

  1. High-effeciency & Good consistency & High passing rate; 
  2. 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.

  1. High-effeciency;
  2. Simple process;
  3. No dimension change.

Infiltration

Infiltrate anaerobic adhesive  into compression magnet's voids by negative pressure.

Apply to extreme environment, such as oil or solvent.

  1. Seal magnet's voids;
  2. Improve strength;
  3. Make it possible to work under oil or solvent for a long time.
