Surface defects is an important issue in sheet metal stamping as the stamping process affects surface appearance and thus influences surface quality.
Defects in sheet metal stamping process.
Identifying and resolving the most common defects in sheet metal forming solving common defects in sheet metal forming.
Generally if experiencing wrinkles during production this could mean the wrong process was chosen.
Metals during fabrication and service.
Digital products metal stamping parts defects in forming.
Surface defects such as cracks and necking.
A great amount of time is therefore spent during the product development process on the optimization of surface defects particularly surface lows during tryout.
The surface unevenness is mainly caused by the unqualified stamping die.
Also known as forming simulation the technology is a specific application of non linear finite element analysis.
This can cause an uneven roll with various amounts of pressure throughout the piece.
6 common defects in sheet metal forming.
Form defects such as fall in wrinkling and marking lines.
During the rolling process a piece of metal will experience a different amount of reduction in certain areas of the piece.
See figure 1.
Two main types of defects typically occur in stamped automotive body components.
Static defects such as surface imprints are not process related but instead are caused by contaminated die or tool faces.
Quality custom metal stampings ranging from 003 to 12.
High surface finish defects at an automotive stamping plant.
Another common defect in sheet metal rolling involves the splitting of a workpiece.
Sheet metal forming simulation is a technology that calculates the process of sheet metal stamping predicting common defects such as splits wrinkles springback and material thinning.
Sheet metal stamping process.
These quality defects can be classified further as static or dynamic.
Wrinkles splits and springback are the three most common defects.
