Curling Sheet Metal Edges

Curling is a forming process that involves de burring sheet metal to produce smooth edges.

Curling sheet metal edges.

Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. Curling curling sheet metal is the process of adding a hollow circular roll to the edge of the sheet. The curled edge provides strength to the edge and makes it safe for handling. This is normally done to eliminate sharp edges.

Sheet metal often contains sharp edges with burrs after it s initially produced. Rounding off sharp edges with radius cutters good and accurate rounding of steel constructions according to en 1090 iso 12944 iso 8501 or imo pspc is becoming more and more important in the metal working industry. 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. Other parts are curled to perform their primary function such as door hinges.

Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end. Curling is a sheet metal forming process used to form the edges into a hollow ring. Other parts are curled to perform their primary function such as door hinges. Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end.

These curls should generally have a diameter of about 10 to 20 times the thickness of the material being worked. Curling is a sheet metal forming process used to form the edges into a hollow ring. Curls are produced in order to shape the material into a hollow ring.
