The process characteristics of roll forming determine the various advantages of roll forming, which makes the roll forming machine widely used in the production of profiles. Its technological characteristics determine that the investment of roll forming is less, it can be put into production quickly, the output is high, and it can realize highly automated assembly line production. And the equipment has high stability, high production efficiency and low defective rate. Equipment maintenance is simple and so on. Below, we introduce the roll forming process in the form of pictures, so that everyone can have an intuitive understanding of the forming process.

What is roll forming?
The process of forming profiles with different cross-sectional shapes through several groups of rollers that are pressed against each other from top to bottom by slicing a certain size of steel plate is called roll forming. The figure below is a schematic diagram of the roll arrangement of the roll forming machine.

Advantages of the roll forming process:
Roll forming process is a new technology led by profile forming. It is energy-saving, environmentally friendly and efficient. Cold-formed products are suitable for many fields, such as construction, decoration, machinery manufacturing, and automobile manufacturing.
, shelves and other industries will be applied. Below, we list the advantages of roll forming.
1. It can be mass-produced, and the production efficiency is very high.
2. The production cycle of a set of rolling forming machine is short and the cost is low. Profiles with different cross-sections can produce different equipment
3. The size standard of the formed products is uniform, the precision is high, and the straightness is good.
4. The surface finish of the profile is good, and the surface-treated profile can also be processed, and the surface will not be damaged by scratches.
5. Other auxiliary processing can be added in the production process, such as punching, welding, embossing, etc.
6. It can form different hardness plates, just need to design different configurations of rolling forming machines.
7. Compared with stamping and forming, it can greatly save time and use fewer workers.
8. A set of equipment can produce profiles of various cross-sections and sizes by changing molds and rollers, which can effectively reduce equipment investment and save plant space.
9. Profiles with complex cross-sections can also be produced

Diagram of the characteristics of the roll forming process
The roll forming process can be classified into transverse bending and redundant deformation according to the different deformation.
1. Transverse bending process: The forming of the metal sheet and strip is mainly transverse bending deformation. The metal sheet and strip can achieve the cross-sectional purpose we need by transverse bending, and gradually become the shape we need by rolling with multiple rollers.

Transverse bending process in roll forming.
Second, redundant deformation:
In addition to the transverse bending deformation, the metal sheet and strip also have redundant deformation. The excess deformation refers to the formation of pre-cut or coil material when the metal sheet and strip enter the roll forming machine. Complicated three-dimensional shapes are finally developed into products.
like:
1. Bend
2. Longitudinal expansion and contraction
3. Horizontal lengthening or shrinking
4. Shearing of metal planes
5. Shearing in the thickness direction of the metal
These redundant deformations are added to the transverse bending process, which greatly affects the forming and shape of the cross-section of the product, and many are related to redundant deformations in the roll forming process.
