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. |
