Resinified alternatives to metal

Highly functional plastic products centering on phenol resin products are used in various automobile-related products due to the outstanding properties achieved by its strong network bridge structure, such as high heat resistance and good chemical resistance. In particuiar, glass fiber-reinforced molding materials excel in strength, rigidity, dimensional stability, and reliability and are used in various elements of mechanisms such as pulley, disk brake pistons, and water pumps.

Special Epoxy Molding Compound For HEV/EV Motor(IPM)
Magnet Fixing

It is the products that contribute to development of HEV and EV which is used by motor. Based on our techniqe that accumulated in an epoxy resin molding compound for semiconductor devices, we developed a electronic material for automotive which corresponds to high temperature and harsh enviroment of the components and possesses high reliability to the large size parts. We supports highly precise positing of the magnet in a motor rotor of HEV / EV and high efficiency for the motor by high strengthening of the material.
