What are the precautions in the stretching process of customized Drilled 125B Mammoth Enclosure? The following editor will explain to you:

Drilled 125B Mammoth Enclosure

    1. Stretching must be cooled to below 50 degrees in the customized Drilled 125B Mammoth Enclosure before it can be moved to the stretching rack for stretching. If the temperature is too high, stretching will not only burn the human body, burn the top, but also because it cannot be thorough. Eliminate the internal stress of the aluminum alloy profile and present absolute waste products such as twists, twists, and poor functions before and after aging.

    2. The stretching amount is controlled at 1%, and it should be noted that if the stretching amount is too high, head, middle and tail scale errors will occur, water-like twists (fish scales) marks on the surface, low elongation, high hardness, and brittleness (low plasticity). Too low a stretching amount will lower the compressive strength and hardness of the profile, and even the aging (quenching) will not increase the hardness, and the profile is prone to bends (commonly known as big knife bends).

    3. In order to control the amount of tensile deformation and very well control the dimensional changes of the entire profile, appropriate special pads and appropriate methods must be selected. Especially for open material, circular 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 ratios, long overhangs, large arcs, large differences in wall thickness, 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 wool strip has the effect of heat resistance, the customized Drilled 125B Mammoth Enclosure 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 and crystallinity. It is a large wide surface, and the thicker aluminum profile should be paid more attention.

    6. In the process of reclaiming, moving and stretching, it should not be rubbed, pulled, stacked, congested, or entangled with each other, and a certain interval should be reserved between each other. The aluminum alloy profiles that are prone to twists and turns and the length of the discharge should be disposed of in time, and if necessary, they should be maintained and disposed of each other.
