Sheet Metal Edge Forming

Extruded holes very close to the part edge can lead to sheet metal deformation or tearing.

Sheet metal edge forming. The curled edge provides strength to the edge and makes it safe for handling. Center of extruded holes a 5 hole dia 2t extruded hole and bend edge c 3t r d 2. Hemming is a technique to join parts together improve the appearance or increase the strength and reinforce the edge of the part. Curling is different than a tear drop hem because in a curl the edge finishes inside itself where a hem leaves the initial edge exposed.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Sheet metal edge shapers make different edge styles on your sheet metal with these forming tools. Curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. With a single tool create both sharp creases and soft curves along the edges of sheet metal.

This is done through the application of force on a workpiece. For over a decade we have supported our customers with specialized precision production sheet metal parts and assemblies prototype to production. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. There is a difference between a curled edge and a tear shaped hem.

In curling the initial edge is rolled into the formed circle whereas in the tear shaped hem the initial edge is still exposed. They come with rollers for turning wiring burring beading and crimping. Spring back is the unwanted tendency of sheet metal to retain or go back to its original flat form after the forming process features such as collars near pierced areas also serve a purpose. Curling is the process of forming a circular ring at the edge of the metal sheet to make it safer for handling.

The edges of the sheet metal are folded over itself or folded over another piece of sheet metal in this forming operation to achieve a tight fit or a stronger rounded edge.
