We are the leading company for precision hardening technologies. Inquiries to this Company Japanese

Electric Machinery and Instruments Manufacturing

Company Overview

Our company not only heat treats and hardens metal products; we also use logical methods to achieve highly-reproductive precision.
That is the basis of ""Fine Hardening,"" the method championed by our company.
It is the only heat treating method that releases zero carbon dioxide, as it uses heat induction.

High-Frequency Heat Inductor: A heat-inducting apparatus used for surface reforming processes such as hardening and annealing, as well as for brazing and other processes. As focused high-power energy can be concentrated on the required locations, it is heat efficient at the same time it makes possible a high-level of precision point hardening. It also requires less space when compared to furnaces, and is beneficial in being energy efficient at the same time it emits zero carbon dioxide.
About Our Company's ""Fine Hardening"" Technology:

1) Contributes to Smaller and Lighter Work:
Fine hardening strengthens only the areas necessary, making possible the minimization and lightening of your company's work design.

2) High Quality Manufacturing is Possible:
We utilize a complete quality management structure that includes electronic controls and operations, allowing for extremely capable quality control. (High Repeatability)

3) Contributes to Process Reductions:
Through targeted heat treatment reductions to polishing and other processes are possible.

4) Zero Emissions
As our heat processing makes use of inducted heat, energy loss is greatly reduced. Additionally, our heat processing equipment is zero emission (does not emit CO2), eliminating the burden on the environment.
Contributes to the carbon offset of our company.

5) Heat Treatment Consulting:
Our company uses its store of experience accumulated over the years to provide its customers with advice on all aspects of heat treating- from material selection and pre-heat treatment methods to the polishing process.
On request, our company can also create prototypes (charged service).

Since our founding we have striven to be at the top of the high-frequency hardening and high-frequency induced heat processing field, and continually better ourselves under the corporate motto of, ""Contribution to Society through Technology."" Although high-frequency hardening is a niche industry, we pride ourselves in possessing technology that cannot be found at any other company. We will continue to develop new technologies that can be turned into products that increase our customers' competitiveness.
