We solve difficult problems with integrated support from carbide materials to finished product manufacturing!
FAQ
What about working with pure iron, pure copper, and nickel?
The reason for a shorter lifespan is due to their affinity with cobalt contained in carbide.
We have received great praise for our MC20 that controls this adhesion with lowered affinity to these materials.

To extend die life of high-speed presses
Lapping of the cutting edge is recommended.
Raising the surface roughness improves sliding and mitigates wear.

What grades do you recommend for punches, dies, and strippers?
It depends on the conditions, so it's hard to say. It also depends on the user.
EF10 for punches and KD20 for dies are used relatively often.
There are cases where ultrafine alloys are not suitable for wire processing such as die-cut blades and strippers (e.g., electrolytic corrosion), so please consult with us first.
