What are the precautions for CAST ALUMINUM ENCLOSURE 1590BBS in the stretching process? Here is an explanation for you:

    1. The stretching of CAST ALUMINUM ENCLOSURE 1590BBS must be cooled to below 50 degrees before the aluminum alloy profile can be moved to the stretching rack for stretching. The temperature is too high, that is, stretching will burn the human body and burn the top. It cannot completely eliminate the internal stress of the aluminum alloy profile, and it is absolutely wasteful such as twists, twists, and poor functions before and after aging.

    2. The control of CAST ALUMINUM ENCLOSURE 1590BBS stretch is around 1%, and it should be noted that if the stretch is too high, there will be head-to-tail scale errors, water-like twists (fish scales) marks on the surface, low elongation, high hardness and brittleness ( Low plasticity). Too low a stretching amount will make the compression strength and hardness of the profile lower, and even aging (quenching) can not increase the hardness, and the profile is easy to bend and twist (commonly known as the big knife bend).
    3. In order to control the amount of tensile deformation and very well control the dimensional changes of the entire CAST ALUMINUM ENCLOSURE 1590BBS, suitable special pads and suitable methods should be selected. Especially for open material, arc material, cantilever material, and zigzag-shaped profiles, more attention should be paid to the reasonable and useful use of stretch clamps.
    4. Pay attention to the force of small feet, thin teeth, long legs, arc surfaces, inclined surfaces, openings, viewpoints, etc. of profiles with high width to thickness ratio, long overhangs, large arcs, large and thin wall thicknesses, strange shapes, etc. In order to avoid the occurrence of defects such as deformation, twisting, and spiraling of the profile part or point-like scale.
    5. Because the tops have the effect of heat resistance, the aluminum profiles with high decorative appearance must be flipped up and down to facilitate uniform heat dissipation and reduce the shortcomings of lateral bright spots that occur due to uneven heat dissipation, especially large widths. On the surface, thicker aluminum profiles should be paid more attention.
    6. In the process of reclaiming, moving and stretching CAST ALUMINUM ENCLOSURE 1590BBS, they must not touch, pull, stack, jam, or entangle each other, and a certain interval should be reserved between each other. The aluminum alloy profiles that are prone to tortuosity and the length of the discharge should be disposed of in time, and if necessary, take care of each other.
