Home » About Us » Greetings

Since its establishment in 1950, Dai-ichi High Frequency Co., Ltd. (DHF) has contributed to society with its original technologies, and built the history of creation until today. Inheriting this history as "the soul of DHF", it has become the driving power of the Company for continued challenges.

At its founding, "high frequency quenching" techniques were provided for the anti-friction of machine parts.
In addition, to prevent the corrosion of steel pipes, the unsophisticated challenge is continued for the application of high frequency heating for customers who are always having trouble with high-frequency lined steel pipes, high-frequency bending pipes that simplify the piping, etc.
In recent years, DHF aims to contribute to society with the creation of new businesses, such as spray-coating formation technology with a combination of thermal spray technology and high-frequency melting technology, plant maintenance technology to which the original high-frequency power supply is applied, and the T-head construction method reinforced steel bars that simplify the bar reinforcement work.

So far, DHF has set up overseas affiliates in China, Korea, Brazil, Taiwan, and Thailand, and expanded technology licensing companies globally in the US, Canada, the EU, etc. In the future, we will strive for the continued creation of overseas business.

All businesses that DHF presents are technologies originally created by DHF that take the lead in the world.
It is only the cool technology that is not unrefined. As a product with the accumulated cool technology of DHF, it makes a contribution to the world, aims to live in harmony with the global environment in the future, and continues for further creation and challenges.

We look forward to your continued support and encouragement.
