Our company manufacture carbide sintered material and finished mold parts.
All products are made in Japan.
We specialize in making carbide for the purpose of extending the life of the mold.
This time, we will introduce the cemented carbide which increases the life of the punching dies and drawing dies.
The product name of the carbide is “R type”.
“Increase your tool life with high quality carbide made in Japan”
"R type" is material that strengthens the binder phase of cobalt.
The matrix hardness becomes higher by strengthening the cobalt phase, and wear resistance and particle holding force are also improved.
Furthermore, corrosion resistance and heat resistance are improved in comparison with general carbide.
In addition, R type can suppress the occurrence of electric corrosion and altered layer due to underwater wire cutting.
Since "R type" can be suppressed for chemical corrosion due to corrosive solution, less rough surface due to the elution of cobalt and it is superior materials in the mold releasability where seizure is hard to occur.
Some of the R type also has materials suitable for drawing of battery cases for automobiles and punching of motor cores.
The R type has been highly evaluated by many customers, and there are many examples where the mold life has been extended several times by using the "R type".
