Hemming is a common metalworking process<\/a> mainly carried out to reinforce an edge, hide burrs or just improve the overall appearance of sheet metal<\/a> parts. When hemming is carried out in a way that a joint between two sheet metal parts is created, it is called seaming but more on that later.<\/p>\n

So, without further ado, let’s dive into the subject.<\/p>\n

What Is Sheet Metal Hemming?<\/h2>\n

Hemming in sheet metal operations refers to the bending of a sheet metal<\/a> edge onto itself. It is very similar to edge stitching in clothes. Similar to how an edge stitch strengthens the edge and makes it more durable, a hem imparts strength to the metal edge and improves its appearance. The edge of one part may also be folded onto another part to create a joint.<\/p>\n

Hemming is usually done in two stages. The first stage creates an acute bend using acute tooling (V die) followed by a flattening of the return flange using a flattening die.<\/p>\n
