Defects In Sheet Metal Stamping Process

How to prevent them.

Defects in sheet metal stamping process.

Defects introduced into 3 52. Identifying and resolving the most common defects in sheet metal forming solving common defects in sheet metal forming. This can cause an uneven roll with various amounts of pressure throughout the piece. Surface defects such as cracks and necking.

High surface finish defects at an automotive stamping plant. During the rolling process a piece of metal will experience a different amount of reduction in certain areas of the piece. Wrinkles splits and springback are the three most common defects. Form defects such as fall in wrinkling and marking lines.

Digital products metal stamping parts defects in forming. The surface unevenness is mainly caused by the unqualified stamping die. Metals during fabrication and service. See figure 1.

Two main types of defects typically occur in stamped automotive body components. 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. Surface defects is an important issue in sheet metal stamping as the stamping process affects surface appearance and thus influences surface quality. The sheet metal forming parts will collide with the surrounding objects in the process of raw material inventory manufacturing.

Another common defect in sheet metal rolling involves the splitting of a workpiece. Also known as forming simulation the technology is a specific application of non linear finite element analysis. Generally if experiencing wrinkles during production this could mean the wrong process was chosen. A great amount of time is therefore spent during the product development process on the optimization of surface defects particularly surface lows during tryout.

These quality defects can be classified further as static or dynamic. 6 common defects in sheet metal forming.
