Curling Sheet Metal Edges

Curling is a sheet metal forming process used to form the edges into a hollow ring.

Curling sheet metal edges.

Curling is a sheet metal forming process that s used to smooth out the otherwise sharp and rugged edges of sheet metal. These curls should generally have a diameter of about 10 to 20 times the thickness of the material being worked. Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end. Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion.

Sheet metal often contains sharp edges with burrs after it s initially produced. Curls are produced in order to shape the material into a hollow ring. Wikimili the free encyclopedia. Other parts are curled to perform their primary function such as door hinges.

Curling is a forming process that involves de burring sheet metal to produce smooth edges. 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. Other parts are curled to perform their primary function such as door hinges. Curls are features that are produced by rolling the edge of a stamped sheet metal part.

The curled edge provides strength to the edge and makes it safe for handling. This is normally done to eliminate sharp edges. Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end.
