Forming (Page 4)

How can you control or compensate for springback in stamped parts when using new, advanced high-strength sheet metals? EWI has recently developed a specialized tool that is capable of assessing springback behavior without any wrinkling or necking on the tested part. The work is described in S-rail Test Tool for Evaluating Springback with High-strength Aluminum...

Shearing the part edges of laser-welded blanks (LWBs) made of steel sheet metal is a challenging and precise process. Recently, EWI conducted studies applying high-speed shearing in the fabrication of steel LWBs with promising results. This work is described in Application of High-speed Shearing for Fabricating Laser-welded Blanks with AHSS and GEN3 Steel, by EWI...

By Henry Cialone President & CEO, EWI Metal stamping has a long history. While there have been changes around the margins, the materials and technologies involved in the process had been substantially static until a decade or so ago. That was when, driven primarily by the needs of the auto industry, lighter-weight, higher-strength steel entered...
