Defects In Sheet Metal Stamping Process

The surface unevenness is mainly caused by the unqualified stamping die.

Defects in sheet metal stamping process.

How to prevent them. Surface defects is an important issue in sheet metal stamping as the stamping process affects surface appearance and thus influences surface quality. Identifying and resolving the most common defects in sheet metal forming solving common defects in sheet metal forming. Two main types of defects typically occur in stamped automotive body components.

Quality custom metal stampings ranging from 003 to 12. Defects introduced into 3 52. High surface finish defects at an automotive stamping plant. 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.

Wrinkles splits and springback are the three most common defects. This can cause an uneven roll with various amounts of pressure throughout the piece. During the rolling process a piece of metal will experience a different amount of reduction in certain areas of the piece. Another common defect in sheet metal rolling involves the splitting of a workpiece.

Generally if experiencing wrinkles during production this could mean the wrong process was chosen. Also known as forming simulation the technology is a specific application of non linear finite element analysis. Static defects such as surface imprints are not process related but instead are caused by contaminated die or tool faces. The sheet metal forming parts will collide with the surrounding objects in the process of raw material inventory manufacturing.

Sheet metal stamping process. 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. Metals during fabrication and service.
