We would like to share about special mention of lower plate.
Could you refer to attached picture?
The red color marked groove,
Our products are conforming with your 3D model.
But on the other hand there is some conflict with your present product sample.
That is to say, The depth of groove of your sample is deeper than our product.
In my view point, this is a significant difference and it is not tolerance problem.
We are going to follow your engineers direction in principle.
However I just share this information because I just sense some risk.
