Hemming Process In Sheet Metal

Hemming process in sheet metal.

Sheet metal is available in a variety of gauges. Hemming is a metalworking process that involves rolling the edge of sheet metal over and onto itself essentially creating an area of two layers. When working with a brake press hems are always created in a two step process. Hems are commonly used to reinforce an edge hide burrs and rough edges and improve appearance.

Hemming is a sheet metal forming process in which sheets are joined by bending it usually to 180. Create a bend with acute angle tooling in the metal 30 is preferable but 45 will work for some circumstances. Seams are commonly used in the food industry on canned goods on amusement park cars in metal roofing and in the automotive industry. Sheet metal hemming process can be generally classified into two major categories such.

Normally hemming operations are used to connect parts together to improve the appearance of a part and to reinforce part edges. The two newly formed layers then lie flush with each other. In sheet metal hemming means to fold the metal back on itself. During this process the edge of sheet metal is folded over.

Hemming is the process in which the edge is rolled flush to itself while a seam joins the edges of two materials. Hemming is a forming operation in which the edges of the sheet are folded or folded over another part in order to achieve a tight fit. Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself.
