the product "U" shape plastic bit deformation
"U-shape" plastic also need to do about 2-3 degrees deformation,the middle area of the "U -shape" ribs should do the material cutting by side. After all the products have been drawn well and then design the "R" radius(also for facilitating the changing, sometimes "R" radius rebuilding
will fail or spent too long time), if some geometrys in customer 3D data are not chamfered, we can chamfer them if they are not affect the parts
assembly (most customers prefer the chamfer the sharp shape with "R" radius).
In addition, some prominent geometry on the product main body are big , this type of product deformation should pay more attention on
parallelism and perpendicularity .
