The shape of dies differs depending on the machine, the use, and what to crush, 

which can cause several potential troubles at assembly. However, 

we are very well-prepared for all the possible troubles. 

Our checking system includes shape checks using checking-plates and accuracy checks of inner diameter. 

At your request, a dimensional inspection report, a mill test certificate, and a heat-treatment test report are attached.

  1. We make dies and cutters based on the specifications and drawings supplied by the crusher makers. We select materials depending on the usage. Suitable quenching and tempering treatments are applied in house.

     Provided a sample die without drawings, we can make equivalents or better dies in quality at your request. 

    ■About materials

    We have improved steels which are originally developed.

    These steels have high toughness and high wear resistance. We keep sufficient quantities for die-size from φ270 to φ700 in stock. We are always ready for your inquiry.
