Tabbed bracket

This part is stamped on a progressive die from thin 0.8mm steel sheet and has many small U-shaped bent tabs with tight tolerances, so each station must be precise to keep the tabs uniform and free of warping or position shift.Burrs need close control since the drawing does not allow harmful burrs, warp or curve.

The embossed “271” mark is 2.5mm high but less than 0.1mm deep, so it must stay clear and in the right position without distorting the surrounding sheet.

Since there is no plating step after stamping, the pre-plates coating on the material must not be scratched during stamping and handling.
