At this point, we can't help but think what kind of modern technology makes the production of color panel door and window profiles?
Cold roll forming
The raw materials of color plate door and window profiles are continuously bent laterally by using the cold bending forming occluding and sealing process and the multi-channel forming roll inside the machine to produce the plates with specific cross-section. In the whole forming process of the color door and window profile, there is only the change of bending deformation, so the basic thickness of the whole plate (excluding the bending angle) remains unchanged after forming.
In addition, roll type continuous cold bending process can be used in the mass processing of color doors and windows with complex shapes. In the forming process, the first roll of sheet metal is connected with the last roll of sheet metal, which makes the raw materials continuously enter the forming machine for forming. This greatly reduces the energy consumption in the forming process of color plate doors and windows. The production process is as follows
Uncoiling - slitting - infrared heating - Film - forming rolling - straightening - cutting - bundling.
The main advantages of the cold bending forming process of color plate doors and windows include: 1. Reduce the material cost; 2. Process the profiles with complex shapes; 3. Reduce the head and tail distortion and opening of the profiles; 4. Reduce the energy consumption and improve the productivity..
I believe that through the introduction of the above forming process of color door and window profiles, if there is a color door and window profile mill nearby, you can easily say its principle!
