3 QCD Concerns


  • “Manufacturing trusted products”
    Stable quality. Commitment to quality during the process.


  • “Fair price and appropriate profit”
    Permanent “Kaizen”. Thorough “5S Program” and commitment to “Unreasonableness, Inconsistency, Waste”eliminate.


    Continuous commitment to quick delivery and achievement of 100% appointed-day delivery rate.
We strive for the balance of these while giving highest priority to quality!!
