1.Introduction

Injection molded magnets are available using ferrite, neodymium-iron-boron, or blends of magnetic materials to achieve an extensive range of properties. Binder types include Nylon 6 and 12, PPS, and Polyamide. The binders and magnetic alloys are capable of a wide range of application temperatures from below -40° C to above 180° C. The Injection molding process is particularly well suited to molding very intricate shapes and thin walled parts. The finished parts can be either very simple or complex in geometry.

2.Materials of injection ferrite magnet: 

Injection plastic-conded magnet is a new kind of composite permanent-magnetic material with the features of flexible shaping, dimensional precision, adjustable magnetic properties, fine coherence, composite molding, elastic magnetization and high mechanical strength.

 

3.Advantages of injection ferrite magnet:

1) The injection molding has a particularly useful feature in large-quantity.

2) The injection molding's magnets values are lower than the compression molding because of their relative low density.

3) The shapes of high dimensional accuracy can be produced without secondary processing.

4.Applications of injection ferrite magnet:

Injection plastic-bonded magnets are now widely applied in core components and parts of micro machine, location sensor, buzzer, contactless distributor for automotive and home appliance industry.
