What are the precautions for aluminum profile manufacturers when processing?
Speaking of aluminum profile manufacturers, many people must know it, and they also know that they produce aluminum profiles, but many of them still don’t know what problems aluminum profile manufacturers need to pay attention to during production. Today, the editor will help you today Let me introduce the precautions in this.

Speaking of aluminum profile manufacturers, many people must know it, and they also know that they produce aluminum profiles, but many of them still don’t know what problems aluminum profile manufacturers need to pay attention to during production. Today, the editor will help you today Let me introduce the precautions in this.
1. For stretching, the aluminum alloy profile must be cooled to below 50 degrees before it can be moved to the stretching frame for stretching work. If the temperature is too high, stretching will burn the human body and wool tops, and because the aluminum alloy profile cannot be completely eliminated. The internal stress of the alloy profile shows absolute waste such as bending, twisting, and poor function before and after aging.
2. The amount of stretching is controlled at about 1%, and it should be noted that if the amount of stretching is too high, there will be errors in the size of the head, middle and tail, water-like twists (fish scales) on the surface, low elongation, high hardness and brittleness (low plasticity). If the tensile amount is too low, the compressive strength and hardness of the profile will be low, and even the aging (quenching) cannot increase the hardness, and the profile is easy to bend in a curved shape (commonly known as a big knife bend).
3. In order to control the amount of tensile deformation and better control the dimensional changes of the entire profile, suitable special clamping pads and suitable methods should be selected for computer gong processing. Especially for open materials, arc materials, cantilever materials, and curved profiles, more attention should be paid to the reasonable and effective use of stretch clamps.
4. Pay attention to the force of small feet, thin teeth, long legs, arc surfaces, inclined surfaces, openings, angles, etc. Situation, to avoid partial or point-like scale deformation, twisting, spiral and other defects of the profile.
5. Because wool tops have a heat-resistant effect, aluminum profiles with high decorative appearance requirements must be turned up and down more, and mechanical parts are processed to facilitate uniform heat dissipation and reduce horizontal bright spot defects caused by uneven heat dissipation and different crystallinity, especially It is a large wide surface, and more attention should be paid to aluminum profiles with thicker walls.
6. During the process of retrieving, moving and stretching, it is not allowed to rub, pull, stack, jam, or entangle with each other, and a certain distance should be reserved between each other. For aluminum alloy profiles that are easy to bend and have long or short discharge lengths, they should be disposed of in a timely manner, and they should be protected from each other if necessary.
The above are the matters that aluminum profile manufacturers must pay attention to when processing, and the staff must also know these, because it will make their work much more convenient.
