This is an isotropic bonded magnet consisting of NdFeB powder produced by rapid quenching method and bonded with resin. Daido Electronics had the first in Japan to commercialize compression molded and injection molded products with high characteristics and high dimensional accuracy in 1987, based on its original compounding and molding technologies.
It can be used for integrated molding and assembly with resin and/or metal parts in injection molding cause of it has high flexibility in shape. This can contribute to process reduction, quality improvement, and cost reduction for customers.

Applications

It is used for various auxiliary sensors in automobiles, medical applications, and industrial encoders.

Production Process

Our NdFeB bonded magnet can be molded in two ways:
・Injection molding
・Compression molding.

Injection Molding

It can be used for integrated molding and assembly with resin and/or metal parts in injection molding cause of it has high flexibility in shape. This can contribute to process reduction, quality improvement, and cost reduction for customers.

Injection molded magnets

Assebly with other parts

 

Features

  1. High level of magnetic properties as Nd-based isotropic bonded magnets
  2. Flexibility in magnetization direction and shapes
  3. Simurateneous molding with other parts is possible

2 Shot Molding

The shot molding is a process in which magnetic powder and resin are molded at the same time.

Features

  • Reduction of bonding and assembly processes
  • Improved coaxiality accuracy
  • Reduction of manufacturing cost

Compression Molding

Compression molded products are made by mixing magnetic powder and binder and press molding. They achieve an even higher level of characteristics than injection molded products.

Compression molded magnets

It can be bonded to shafts and/or yoke materials in house

Features

  1. High level of magnetic properties as Nd-based isotropic bonded magnets
  2. Flexibility in magnetization direction and shapes

Magnetic Properties

*Compounds for injection molding can also be provided.
