Plastic Injection Magnets

①The Traits And Applications Of Plastic Injection Magnets

A. Plastic Injection NdFeB

Traits: Have The Rigidity And Elastic, Can Be Processed Into Thin-Walled Ring, Rods, Slice And Various Special Complex Shapes. Can Make The Magnets And Other Metal Inlays (Gear, Screw, Dysmorphism Hole Etc.) A Time To Shape, It Is Not Easy To Have The Crevasse And Break. Magnets Need Not Cutting And Mechanical Processing, The Product Yield High. After The Formation, The Tolerance Precision Is High. The Surface Is Bright And Clean, The Magnet Internal Uniformity Is Good. The Surface Magnetic Field Uniformity Is Good, The Corrosion Preventing Is Strong.

Applications: Mainly Used For Sensors, Brushless Motors, Automobile Electronic Throttle Pedal, Car Instrument, The Car Instrument Driver, Auto Speed Table, Fuel Table, Etc.

 

B. Plastic Injection SmCo

Traits: Can Make Complex Shapes For A Time To Shape, The Inlays’s A Time To Forming Which Shaft Or Sleeve Etc. Reduce Assembly Process, Improve Assembly Accuracy. With Strong Corrosion Resistance, Generally Don’t Need To Surface Treatment, And Have High Temperature Stability.

Applications: Apply In Automobiles, The Copier And Other Precision Machine. There Are Many Need In High Temperature, Humidity Environment The Magnetic Induction Instrument Must Use The Material.

 

C. Plastic Injection Ferrite

Traits: The Plastic Injection Ferrite’ Magnetism Performance Compares The Plastic Injection NdFeB Magnet To Be Low, But Its Price Is Inexpensive.

Applications: Suitable To Use In The Sensor, The Shape Is Complex, Magnetism Performance Requirement Relatively Slightly Low&Rsquo;S Electrical Machine Product Etc.
