Defects In Sheet Metal Stamping Process

What are some of the possible defects in drawn sheet metal.

Defects in sheet metal stamping process.

Dissecting defects part i the fabricator. Metal stamping is a cold forming process that makes use of dies and stamping presses to transform sheet metal into different shapes. Also known as forming simulation the technology is a specific application of non linear finite element analysis. Process control for sheet metal stamping process.

Choosing the wrong size blank under estimating the number of forming tools required or encountering an unexpected wrinkle or split can be very costly if only discovered during first physical tool tryout. 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 sheet metal forming parts will collide with the surrounding objects in the process of raw material inventory manufacturing and shipping. There are two reasons behind this defect.

Sheet metal forming a review welcome to tms. Sheet metal stamping defects list sheet metal stamping. Icass stamping defect correction sheet metal. The most common sheet metal stamping defects are also the easiest to predict using advanced simulation software such as autoform.

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. One is the improper handling another one is the elasticity of sheet metal forming materials. Dynamic defects are process related and are caused by the forming process. These defects are corrected simply by cleaning the die or tool surface before stamping.
