This short video shows a stamping operation used to form a curled edge on a sheet metal component. During the process, dedicated tooling gradually bends the edge into a rounded profile while controlling its radius and alignment.
Edge curling turns an exposed sheet metal edge back toward the part to create an open or closed curl. Compared with an unfinished cut edge, the rounded profile is easier to handle and can provide additional stiffness along the edge of the component.
The final result depends on the material thickness, ductility, curl diameter and tooling design. Consistent die positioning and controlled deformation are needed to reduce cracking, distortion and excessive springback. A more detailed explanation of tooling methods and design considerations is available in our guide to curling sheet metal.
Curled edges can be used as protective borders, reinforcing features or functional elements for later assembly. Depending on the component design, curling may be combined with blanking, punching, bending and other stamping operations in a multi-stage production process.
MAXTECH provides sheet metal curling edge services for parts made to customer drawings. Material type, sheet thickness, curl radius, dimensional requirements and production quantity are reviewed before the tooling and manufacturing process are determined.
Send us your drawings and material requirements to discuss a suitable edge-curling process for your stamped metal parts.
