Curls are features that are produced by rolling the edge of a stamped sheet metal part.
													
																	Curling operation in sheet metal. 
									
	
		
	
																	Curling is a sheet metal forming process that s used to smooth out the otherwise sharp and rugged edges of sheet metal. 
																	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. 
																	Curling the forming of an edge having a circular cross section along a sheet or around the end of a shell or tube. 
															
													
									
	
		
	
																	Curling can be performed to eliminate sharp edges and increase the moment of inertianear the curled end. 
																	Curling channel u bending air bending offset bending corrugating and tube forming. 
																	Curlingis a sheet metal formingprocess used to form the edges into a hollow ring. 
																	Curls are produced in order to shape the material into a hollow ring. 
															
													
									
	
		
	
																	Other parts are curled to perform their primary function such as door hinges. 
																	Curling is a sheet metal forming process used to form the edges into a hollow ring. 
																	Sheet metal often contains sharp edges with burrs after it s initially produced. 
																	Other parts are curled to perform their primary function such as door hinges. 
															
													
									
	
		
	
																	These curls should generally have a diameter of about 10 to 20 times the thickness of the material being worked. 
																	Sheet metalworking cutting and forming thin sheets of metal usually performed as cold working sheet metal 0 4 1 64 to 6 mm 1 4in. 
																	Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end. 
																	Curling is a forming process that involves de burring sheet metal to produce smooth edges. 
															
													
									
	
		
	
																	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. 
																	This operation is sometimes called false wiring.
