Company Profile

Corporate philosophy

Our company has researched and developed processing tools using ultrasound since its establishment.

We have delivered our products to manufacturing sites in various fields.

Ultrasound is an acoustic wave with high frequencies which cannot be heard by the human ear.

At present, ultrasound is known through various usages, such as examination machines for medical use, detectors, humidifiers, and washing machines.

Ultrasound’s safe and clean energy cannot be heard or seen, but it is strong.

The technology to process various materials using oscillating ultrasound waves is utilized in SONOTEC’s ultrasound processing tools.

Recently, ultrasonic cutters have become indispensable tools at manufacturing sites for familiar goods.

Our company’s products are easy-to-use, small-sized machines among ultrasonic processing tools.

Support, information disclosure, and maintenance services after the sale of our products are important to us.

We believe that growing along with our customers and the development of ultrasonic processing technology are our roles. We will endeavor to propose various usages for ultrasound in the future to contribute to society.
