How do I fix wrinkles on my face?
-
In general, if wrinkles appear during production, it may mean that the wrong process was chosen to produce the part or that an important process parameter (such as binding strength) is incorrect. Wrinkles occur when the sheet metal stamping process produces compressive stresses that "push" the material against each other, causing the material to overlap in the worst case. A thicker material can withstand compressive forces better than a thinner material - in general - and therefore a thinner material will wrinkle more easily.
