6 key! Comparison between stretch bending VS roll bending
Stretch-bending and roll-bending processing are two commonly used stretch-bending processes for aluminum profile bending manufacturers.

Video of bending angle by profile bending machine
In the video, we conducted angle iron bending tests according to customer requirements.
Angle iron is one of the more relaxed capabilities in the bending capacity of the profile bending machine, and it is also more widely used. At this time, we can also call it an angle bending machine.
Not cold knowledge! It is the advantage and use of cold bending.
Cold bending Cold bending is the most successful method of bending steel for use in construction and industry. In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Mechanical stress is used… Read More »Not cold knowledge!

How is Section Modulus Used in Profile Bending Steel?
Section modulus is a measure of the shape of the crosstie and is calculated by dividing the MOI by the greatest distance of the section from the neutral axis, calculated from dimensions and rectangular cross-section.
2019 Everyone should know about bending steel
Bent steel components don’t just “walk out” of the rolling mill. Bent steel members are made of straight materials and are bent by your bending company to your requirements.
The bending process does not affect the strength or structural integrity of the steel. When the shape is successfully bent without any buckling or local cracks in the steel, under actual conditions of use, the component will withstand much less stress than that associated with the bending operation. Once the bending is completed, the member can be expected to perform as needed.
Advantages of cold bending metal profiles
When you need to bend various types of metal profiles, cold bending has many advantages over hot bending.
Whether you are dealing with any other shape of beams, tubes, channel or angle, sometimes 3D, 4D or even 5D bending is required so that they can reach the desired angle.
What factors affect the rebound when the section bending machine is working?
The resilience of the profile bending part refers to the phenomenon that the shape and size change after the plastic deformation of the profile makes the bending part leave the mold.
The degree of springback is usually expressed by the difference between the actual bending angle of the workpiece and the bending angle of the mold after bending, that is, the size of the springback angle.
The ins and outs of extrusion bending
Extrusions are everywhere—in conveyor systems, scaffolding, playground equipment, swimming pools, and furniture. They also are key components in architectural windows and automotive window trim. We are surrounded by bent extrusions and their close cousins, bent rolled formed sections. Managing the… Read More »The ins and outs of extrusion bending
