The manufacturability of Metal stamping holes
The manufacturability of metal stamping holes when the holes and pitch of holes are keypoints
When there are only two Metal stamping holes and pitch are important dimensions , the best stamping shape are as picture 1-1 showes. However, for the better appearance, Picture 1-2 is looks better ,but the stamping is not as good as 1-1 due to easy deviation. The round head 1-3 is much more worse for deviation than 1-2. The situation is same for more complicated shape items (Pciture 1-4 )
When you need radius on the cornor,please keep in mind that don’t make the arc tangent to the streight lines. For examples 1-5 and 1-6 .
