MURAMASA STRONG type[S] Excellent Strength

  • typeS (High strength type)
  • typeK (High toughness type)

typeS (High strength type)

Products of this type have excellent pressure resistance as a result of employing material with higher strength than conventional materials.
As any type of surface treatment can be applied with this material, this type can be used in many different ways depending on the usage.

POINT1Toughness of punches allows for lower tableting pressure
Toughness offered by the punch material provides superior transfer of tableting pressure.
This allows for tableting using lower pressure because the pressure can be transferred to tablets without loss.
This results in reduction of the occurrence of capping.
POINT2Highly flexible heat treatment
With our unique heat treatment technology, the punches are manufactured in such a way that the part where the rollers come in contact has lower hardness than the tip.
In this way, we managed to achieve both the toughness of the punch tip and the peace of mind that the machine will not get damaged.
These are the unique specifications of NANNO realized only by heat treatment technology using salt baths.


Super hard alloy is applied in the interior of the die by shrink fitting in order to enhance wear resistance.
The shrink fitting dimensions are specified internally and managed so that problems such as loosening should not occur.
This type of die offers outstanding wear resistance in comparison with standard steel dies.
