What is Rollforming Technology?

Rollforming can be called as a step-by-step bending process of the sheet in roll form, by opening it in the uncoiler and passing it between the rollers and stands called the forming mold, until the desired cross-sectional dimensions are reached. It is the most suitable method for the production of long and multiple profile sections.

Ralform Lines​

Ralform lines are a critical product that allows coiled sheets to be bent in many steps and makes it possible to carry out these operations without any problems. As it is known, coiled sheets come to the fore with their difficult-to-process structures, and a lot of power is required to bring these sheets into the desired shape. The machines called Roll Form Line make it possible to carry out these processes quickly and easily, thus saving time.

What is Ralform Lines?

The question of what are Ralform lines makes it possible to have information about what these machines, which have a special position in the industry, are and what functions they are used for. The Ralform line, which is a very functional machine for the production of long and multiple profile sections; It enables the sheet in roll form to be opened properly and to be bent until it reaches the desired size, and in this context, it makes it possible to save time and manpower.

What are Ralform Line Functions?

The Ralform line has many functions and these functions can be listed as follows:

Forming of pre-drilled and blanked sheets
Shaping of sheet metals that have been punched after Ralform forming, their middle or edges have been emptied, or they have been formed with intermediate bends
Waste-free shaping of pre-cut material
Performing welding, drilling and cutting to length at the end of the line in the Ralform line

The features that can be listed as above are known as ralform line functions, and because of these functions, machines are preferred in the field for the industry.

Ralform Line Units

There are different units within the scope of the Ralform line and these units ensure that the machine has a functional quality. The units mentioned can be listed as follows:

Uncoiler unit
straightener unit
roll loading trolley
guillotine scissors
Roll form reels
automatic feeding
automatic stacking system

Each of the units listed as above and included in the Roll Form Line Units makes it possible for the machine to operate in a functional way, and enables the coiled sheets to be bent professionally and in a short time, within appropriate steps, and to bring the roll sheets into the desired form.

What are the advantages of Rollforming?

Rollforming enables to produce the desired cross-section profiles in the narrowest tolerances and at the same size continuously. It provides serious savings in production time by performing operations such as drilling and inflation with other additional press units that can be found on the line. Profiles produced by the rollform method have higher structural strength than those produced by other methods. Thin section and tubular profiles, which are difficult to produce with other methods, can be produced.

Is rollforming an economical method?

Yes. Rollforming is the most economical production method for many companies in terms of both production speed and overall costs. Especially in high-volume production, Rollforming is preferred because it has a continuous and high speed. Production cost is reduced as an experienced Rollforming Line manufacturer can also solve other operations on the profile on the same line. In short, the advantages are; less components, less additional labor and reduction in production costs.

Can every section be Rollformed?

Many cuts can be made. Although not every section seems suitable for rollforming, it is useful to evaluate its feasibility by considering the advantages shown above. In many cases, an experienced rollform manufacturer can suggest alternative designs.

What does it take to design and manufacture a new part?

On-demand rollforming is a creative process. An experienced rollform maker can guide you. Many redesigns can be introduced to reduce costs and simplify both manufacture and assembly.

Do rollform parts reduce labor and inventory costs?

Yes. Since the parts produced with rollform will be of the same size, it does not cause problems in assembly. This also provides free space in the production area and reduces the amount of scrap/waste. It also saves labor by eliminating additional operations.
In which industry areas is it used?
Parts produced with rollform can be used in any industry. Many precision industries prefer rollforms as tight tolerances can be achieved
