Among our specialist business fields,
there are major opportunities in hard coating technologies.
Our first involvement in hard coating technologies came with the first-ever practical use application in Japan of CVD coatings, as an elemental technology in rotary engine production. Since that time, the demand for hard coating has increased with the requirements for high precision machining and improvements in productivity in various industries, creating new opportunities for business expansion at Toyo.
Increased demands for enhanced abrasion resistance characteristics in forming dies, and a variety of tools, were answered by a move toward products with very hard coating based on titanium. Additionally, we have developed coating technologies based on chrome and carbon for areas which require easy mold-release, anticorrosion, or anti-oxidation. We have the top market share in the field of CVD coating method, in which a highly reactive gas is used as the medium to form a coating layer on work surfaces. We are also working to achieve technical advances such as the PVD coating method, which can form the TiC coating with less deformation than the conventional CVD method.
We also introduced the first in Japan, ultra-large nitriding furnace (PPD furnace), making it possible to apply nitriding to improve the durability of large dies, such as casting dies for automobile exterior panels.
Currently, in addition to our piece charge business, we are expanding our commitment to through processing, from pre-machining of the material to be treated right through to coating. In particular, in the area of high-precision stamping dies, we not only design and manufacture die sets but also do prototyping and evaluation using dies, In the years ahead we plan to expand our business activities to cover many other fields including the life sciences, data communications, energy and the environment, and nanotechnology.
