It is really a strange case, we had forwarded all the pictures to stock and production yesterday and we checked stock left and production recored
1. There are 41 pcs 4mm A grade in stock, produced at the same time as order 44, see the attached pictures, they are very flat, see the attached pictures; as we discuss if you got the sheet from the container like what you showed us in the pictures, that problem must from production, it should not from loading; and we checked the production recored and found out these sheets are control good condition, like the attached pictures. that problem is very visible, if they came out from machine like that shape, it will not get approval, and it will be ship to customer.
2. We also checked 5mm, 6mm in stock (produce at the same time as order 44) so far we didn;t found the that problem in our stock sheet;
We can;t find what and how to cause this problem. very confuse.
Yothin please do us some more favors:
1. Check how is the warping for 4mm, the highness point in length side and the highness point in Width side? how many mm from the sheet to ruler.
2. How many 5mm A Grade having this problem?
