Thank you for checking the stock.
430 Nichiro inventories are being also checked, but similar stock isn't found.
But it's NG by a customer.
It's necessary to investigate the cause, so please submit an origin. I'm thinking it's necessary to crush a factor.
Thank you.
The contaminant is stuck in the surface.
It also exists in cover Assy and an inner pipe.
It's possible to peel from the surface, but the analysis in nichiro is impossible.
It'll be an analysis at outside.
Therefore please tell me an ingredient of cleaning solution and combination in front of the coat.
When there is something to agree, it'll be one of factors.
The occurrence in shipment after a while is very difficult to consider.
Because it isn't rust.
