Roll forming machine is a type of machine used to create long, linear metal pieces from coils of metal. This process is known as roll forming. Roll forming machines typically have a series of rolls, or dies, that the coil of metal passes through. Each set of rolls performs a specific function in shaping the metal piece to the desired shape. There are many different types of roll forming machines, each designed for a specific type of roll forming process. Common roll forming machines include: -Slitting machines: These machines cut the metal coil into narrower strips that can be processed by other roll forming machines. -Cut-to-length machines: These machines cut the metal coils into shorter lengths that are ready to be used or shipped. -Precision roll formers: These machines create very precise, small components using a variety of materials such as aluminum, brass, and stainless steel.

Roll forming is a continuous metal forming process in which a sheet of metal is passed through a set of rolls, or stands, each performing one or more operations until the desired shape is achieved. The major benefit of roll forming over other metal forming processes is its ability to produce long lengths of complex shapes with a high degree of accuracy and consistency.
