Quality policy
To achieve quality, cost, delivery times, and safety that satisfy customers, we seek to clearly set forth our organization and divisions of roles and responsibilities and to make sure that all employees enhance their skills and strive side by side to continuously improve the quality management system.
All employees strive together to strengthen our quality controls.
To meet changing customer needs, we strive to strengthen our quality controls on a daily basis. As part of these efforts, we’ve obtained ISO 9001 certification, a first for the head plate industry. In addition, we’ve obtained JIS mark certification, a first class pressure vessel manufacturing license, and welding certificates under the Electricity Business Act and the High Pressure Gas Safety Act. Drawing on extensive experience, our machining technologies for special materials like titanium, copper, aluminum, nickel, inconel, incoloy and zirconium have been warmly received.
