In the roll forming process, a metal strip is fed through a series of matching roll-forming dies, which are mounted on the shaft of the forming stand of the rolling mill. If the component to be produced requires other functions (holes, slots, cutouts, lugs, etc.), the manufacturer needs a punching machine or other equipment. Some functions are better introduced before forming, while other functions can be processed after forming.

If the component is made from curled strips (as opposed to blanks or pre-cut strips), the roll forming line will usually include a cutting press or saw. The ability of the roll forming line (coil feeder and pre-punching equipment, roll forming machine and cutting equipment) to handle part design depends on many factors. If you only look at the outline (cross section) of the component design, the key factors include:

Material thickness

Material type

Outline size

Configuration file complexity

Let’s take a look at some typical design features of roll forming machines. The fit between the component design and the ability of the roll forming machine (or rolling mill) to form the component is related to the following characteristics:

Roller diameter

Roller space

Roller spacing (especially vertical)

Number of forming stations

Cutting equipment

We will use the professional design software Copra to reasonably match the above configured parameters to give you a reasonable solution.
