Find out why and how presidents of MOBIO exhibitors started "INNOVATION and CHALLENGE" through the special interview. The latest "Meet the President" article is Mr. Shimonishi of SHIMONISHI SEISAKUSHO CO., LTD.

SHIMONISHI is an industry pioneer, turning invisible magnetic fields visible, and built a framework of harnessing decades of data.

R) Magnetic field verification

●Magnet Products Driving Diverse Markets

The company's various magnets, designed to generate optimal magnetic fields for embedded devices, are widely used across automobiles, home appliances, and electronic equipment.

Introducing practical applications, Shimomichi remarked, 'Magnets are not outwardly visible parts, so their existence may be less apparent.'

*The braking device used in compact amusement park roller coasters is a magnetic brake, where metal plates on the cars pass between magnets on the rails, generating eddy currents whose repulsive force slows the vehicles smoothly.

*Japanese ATMs and other currency handling machines utilize the company's products, which read the magnetic ink on banknotes through magnetic sensors to distinguish genuine notes.

The widespread use of the company's products stems from its early lead in introducing 3D magnetic field analyzers and the technology to apply them effectively.

●Revolutionizing Manufacturing with 3D Magnetic Field Analysis

L) Magnetic field design

R) Magnetization of thin materials

Enabling visual and numerical analysis of magnetic field strength, distribution, and flux, the technology makes data‑driven design possible instead of depending solely on intuition or past experience. Moreover, it is possible to understand how the magnetic force changes not only in the magnet itself but also when incorporated into a product, eliminating the need to create prototypes.

By comparing simulation results during design with measurement data from actual production, a system naturally developed to record and accumulate discrepancies and their causes. This vast accumulation has now become an important resource for responding to technical inquiries from customers

Shimonishi expressed a strong determination to build on their accumulated expertise and venture into new domains and remarked, 'I hope our team members will take an interest not only in magnets but also in cutting‑edge technologies.'
