Fontijne Grotnes Rotary roll forming is a cold rolling process capable of forming profiled configurations to close tolerances in cylinders, conical shapes, hoops and rings. This process is desirable when good surface finish and fine detail are required. When producing parts of different diameters having the same profile, tooling costs and setup-time are minimized.

 

Rotary roll forming of circular parts is a precision process in which thick-walled rings are formed between dies that displace material both axially and radially to attain the desired shape. This process greatly reduces and, in many cases, completely eliminates machining.

Rotary roll formers have been found practical for many applications:
