The process of HIP diffusion bonding

The joint surfaces of the completed shape of the part and the work method for the capsule assembly are examined, and part manufacture is executed under consideration of the shape of each part and the finishing allowance.

Part ManufactureDirt, oxide layers, etc., are removed completely from all parts, and then all the connection parts are sealed by welding with capsule material with good weldability to prevent oxidation.

Capsule AssemblyThe capsule is checked for leakage, and then the inside is evacuated for vacuum sealing. At this time, heating is done during the evacuation in order to obtain a higher vacuum. This step is not required when capsule assembly is done by EB welding.

Vacuum Sealing

Finishing machining to the final shape is performed.

FinishingThe capsule is removed by machining and the joint is examined for soundness (UT, PT, etc.).

Capsule RemovalHIP treatment is executed under the required diffusion bonding conditions.

We introduced military specifications early on in the fields of defense-related equipment as well as equipment related to aviation and space exploration, and on the basis of these specifications, we have contributed positively to the application of the specifications of aircraft manufacturers. The management system that cleared these extremely strict specifications is applied not only to products related to aviation and space, but to all of our products, and it has been appraised highly by various quarters.The transition from military specifications to ISO 9000 was also started rather early on, and efforts to raise the standards of the management system by acquisition of certification for special machining in fields such as aviation and space continue.

Total Quality Assurance System Based on the ISO 9000 Series

ISO14000 series

Special Process Control System

Acquisition of ISO 9000 certification did not end simply with acquisition of the certification, but the conventional quality assurance system was revised from the bottom up and an original system was established aiming for even further improvement. This has unified the ISO requirements with the immense amount of expertise acquired by the Company over many years, and a total quality assurance system has been realized.Our ISO 9001 accredited plants are Himeji, Gunma, Shiga, Ibaraki, Kanagawa, and Chiba. With our new Toki Plant scheduled to acquire accreditation by September 2017.Our JIS Q 9100 accredited plants are Himeji, Shiga, Chiba, and Kanagawa. With our new Toki Plant scheduled toacquire accreditation by September 2017.

We are accredited for environment management system ISO14001 as one of our environmental activities.We are positively tackling environmental issues in order to protect nature. We also continue to contribute to environmental preservation through energy saving, recycling, and environmentally friendly material through our sophisticated metal technology practices.Our ISO 14001 accredited plants are Himeji, Gunma, Shiga, Ibaraki, Kanagawa, and our Technical Center.

In regard to temperature control, which is considered vital to special processes with heat treatment equipment, HIP equipment, etc., we have developed a system for fully automatic temperature distribution measuring/measuring equipment calibration, and strict verification executed periodically. In addition, all product parameters are registered and stored in a computer, enabling manufacturing of many products in small lots.

Nadcap (National Aerospace and Defense Contractors Accreditation Program) is the world’s only unified accreditation program for special manufacturing processes for parts in the aerospace industry. Nadcap accreditation is a requirement for special manufacturing processes for parts in aerospace industries, as very strict quality control and audit system is mandatory in order to receive accreditation. Our Shiga and Himeji plant are Nadcap-accredited for heat treatment.
