Products

The magnets we produce are used in your familiar environments such as automobiles, home appliances, housing equipment, and office equipment.

There are various types of magnets. Our injection-molded magnet is molded in a mold using a composite material made by kneading magnetic powder and a resin binder. It is also called a plastic magnet and has the following features.

Complex shapes

Monolithic molding with other parts

High dimensional accuracy

Impact resistance

Lightweight

Ferrite injection molded magnet

Strontium ferrite is used for the magnetic powder. 
It has good cost performance.

Rare earth injection molded magnet

A magnet that uses rare earth metals (neodymium and samarium) as magnetic powder.
Although it is more expensive than the ferrite type, it features high magnetic properties.

Injection molded magnet assembly

Injection molding magnet, metal parts, and resin (PPS, PBT, POM, PC, etc.) are integrally molded.
By doing this, there are advantages such as improved performance and accuracy, reduced man-hours, and prevention of cracking by press fitting.

Sintered/compression molded magnet assembly

We also handle insert molding of fragile magnets such as sintered and compression molded magnet.
We have extensive experience in automobiles and office automation equipment.
