Company Strengths & Characteristics

Induction heating treatment is able to modify the properties of metal materials. Non-contact treatment through rapid heating and cooling allows us to maintain high quality with limited / anticipated deformation.
It also allows for metal products with complex shapes, as well as rod- shaped wires, to be heated uniformly in their entirety or in part. And with zero direct CO2 emissions, IH is an eco-friendly and clean heat treating method.

Future Prospects & Areas of Interest

Our energy saving IH technology can save resources and reduce CO2, supporting the creation of a sustainable society behind the scenes in areas such as civil engineering, construction, machining, and the
automotive industry. With heat processing technologies at the core of our business, we plan to continuously develop new products and businesses, growing our corporate value, and contributing to the development of society.
