Title: Innovations in Coating Technology: The Contributions of Michio Mitsui

Introduction

Michio Mitsui, an esteemed inventor based in Yokohama, Japan, has made significant contributions to the fields of electrostatic coating and atomization technology. With an impressive portfolio of 21 patents, Mitsui’s innovations have paved the way for advancements in painting techniques, particularly in maintaining high-quality finishes while improving efficiency.

Latest Patents

Among his latest inventions are the rotary atomizing electrostatic applicator and the shaping air ring for the same. This innovative rotary atomizing electrostatic applicator addresses the challenge of balancing increased paint discharge rates with the maintenance of painting quality. It features a bell cup that is hit by atomization air at an angle of 90 degrees or less, coupled with first air holes that discharge atomization air directed at the back of the cup. These air holes are strategically arranged and oriented inversely to the rotation of the bell cup, ensuring that the atomization air is twisted at an optimal angle. Such innovation significantly enhances the painting process.

Moreover, he developed an electrostatic coater that is capable of achieving high-level coating quality. The shaping air is discharged radially outward, ideally at an elevation angle between 10 and 20 degrees, and is twisted to counter the rotation of the bell cup. This design allows paint particles to extend from the bell cup’s edge and collide with the shaping air at a strategic point, thereby optimizing the painting dynamics.
