Announced details
Pumps serving social infrastructure, river drainage pumping stations, drainage pumping facilities, stormwater pumping stations, and critical pump refurbishment at private-sector plants in industries such as power and chemicals
The lead time was shortened from approximately 6 months to 1.5–2 months. Production can be completed in as little as 2 weeks. No cracks occurred in AM-manufactured impellers during a liquid penetrant test conducted after continuous operation testing. The corrosion mass-loss rate of the AM material was a fraction of that of conventional cast stainless steel.
Actually applied in refurbishment work at a river drainage pumping station in Hyogo Prefecture
The disclosure states that quality verification was conducted in collaboration with academic institutions and others, but the specific institutions and relationship are not disclosed.
In this announcement the company addresses none of Contract Value / Offering price / Impact on Business Performance.

Items this document does not state (13)
These are items the company does not state in this document. We do not leave them blank, nor fill them in from other sources or by inference.
The reasons the company gives
The company's own explanation, not something inferred from the numbers.To address tight project schedules caused by unexpected corrosion in aging pump components and ensure reliable restoration within the limited construction period during the non-flood season. Metal AM eliminates preliminary processes such as making wooden patterns, while forming components as a single piece to reduce corrosion and weaknesses at joints.
