TECHNOLOGYDHF's Technological Capabilities

Since our founding, DHF has been involved in a great number of projects to develop new technologies. In the past, those have included high-frequency hardening of railway rails, the bending of pipes using hot plastic properties via high-frequency induction heating, and many other “World First's” that we have brought to the market. As a result, we have received many positive evaluations that have contributed to our good reputation. Furthermore, we now have expertise in the fields of materials science, chemistry, mechanical engineering, electronics, constructions, and many others. In more recent years, we have been joined by staff specialized in a broad variety of fields, including food, automobiles, environmental science, medicine, construction, and other fields. Responding to a vast variety of needs, our company is committed to contributing to society at large by making its unique technologies widely available.

CORE TECHNOLOGYDHF's Core Technologies

There are many DHF technologies that could be called "core". The technologies that we have developed and continue to develop are being put to use throughout the world in all kinds of fields. Other companies cannot compete with us in terms of reliability and durability.
