(1) The aluminum profiles of aluminum profile manufacturers on the cooling bed shall not be rubbed, pulled, overlapped, crowded or entangled with each other during the process of taking materials, moving and stretching, and a certain interval shall be reserved between them. The profiles that are easy to bend and have a long discharging length should be handled in time, and they should be protected when necessary.

(2) The profile must be cooled to below 50℃ (which can be grasped by bare hands) before it can be moved to the stretching frame for stretching. If the temperature is too high, stretching will not only burn the human body, but also burn the tops. Moreover, because the internal stress of the profile cannot be completely eliminated, there will be absolute waste products such as bending, twisting and poor performance before and after aging.
(3) Because the tops have the function of preventing heat dissipation, the profiles with high decorative surface requirements must be turned up and down, back and forth, so as to facilitate uniform heat dissipation and reduce the transverse bright spot defects caused by uneven heat dissipation and different crystallinity, especially for profiles with large width and thick walls.
(4) Pay attention to the stress on the feet, thin teeth, long legs, circular surfaces, inclined surfaces, openings and angles of profiles with high width-to-thickness ratio, long overhanging walls, large radians, different wall thicknesses and strange shapes, so as to prevent the occurrence of defects such as local or point-like dimensional deformation, twisting and spiraling of profiles.
(5) The stretching amount should be controlled at about 1%. For example, the stretching amount of a 25M profile should be stretched by about 25CM after straightening the profile, but it must not exceed 2%. In production, it should be adjusted according to the actual situation of profile discharging and various specific requirements (opening size, surface quality, external size, internal diameter size, wall thickness, elongation, etc.), so as to find the stretching amount that can meet various specific requirements at the same time in contradictory technical requirements. Excessive stretching will lead to head-to-tail size deviation, water-like twist (fish scale) marks on the surface, low elongation, high hardness and brittleness (low plasticity). Too low stretch will make the compressive strength and hardness of the profile low, even aging (quenching) can not improve the hardness, and the profile is easy to bend in an arc (commonly known as broadsword bending).
(6) In order to control the tensile deformation and better control the dimensional change of the whole profile, appropriate special clamps and appropriate methods should be adopted. Especially for opening material, arc materials, cantilever materials and curved profiles, more attention should be paid to the rational and effective use of the tension clamp pad. If necessary, someone should hold the centralizer or plug pad in the middle of the stretched profile to ensure that the stretching dimension between the head, middle and tail sections meets the profile requirements.
What are the three principles in the daily procurement of industrial aluminum profiles?
After the surface of industrial aluminum profile is oxidized, its appearance is very beautiful, and it is dirt-resistant. Once it is coated with oil stain, it is very easy to clean. When assembling into products, profiles with different specifications are adopted according to different loads, and supporting aluminum profile accessories are adopted, which is environmentally friendly, light and convenient to install and disassemble, and extremely convenient to carry and move.

First: don't choose very cheap.
The explanation is as follows: the cost of aluminum profile = spot price of aluminum ingot+processing cost of extruded aluminum profile+packaging material cost+freight.
These are very transparent, and the cost of aluminum profiles is similar, which is obviously lower than the market price. The first possibility is that the weight per meter is less; The second type: aluminum ingots use recycled waste aluminum; The third type: enlarge the blanking loss (not sold according to the actual number of meters).
Second: Do not choose suppliers who only know the sales materials.
The explanation is as follows: prepare some goods, recruit a few wiring ladies, and do a lot of promotion online to open the business. It is our buyers who are often hurt. Most wiring girls don't know how to use it, only know the unit price. How to use it to meet the needs of customers; How to make the most cost-effective; Which connection method is the best in different venues; They can't answer these questions accurately. Only know to recommend the cheapest profile and the cheapest connection method;
This connection method is the lowest cost, but it is the most labor-intensive and the worst strength. The convenience of aluminum profiles will not be reflected at all, and it will bring great trouble to future transformation. But the wiring lady will advocate a way.
Thirdly, choose the aluminum profile suppliers that focus on production.
The explanation is as follows: aluminum profile suppliers who are mainly engaged in production are generally engaged in this industry for more than 5 years, and they are also users. They have rich practical experience and have a good understanding and mastery of the quality and performance of products. They will recommend products that are suitable for customers' needs and choose convenient and practical accessories.
Industrial aluminum profiles are widely used and highly versatile. They are famous for their environmental protection, convenient assembly and disassembly, time saving and long service life. Industrial aluminum profiles have many varieties and complete specifications, which are suitable for various types of mechanical devices; No need for welding, convenient size adjustment and easy structure change; Strict dimensional tolerance and high surface finish requirements; The assembly work is convenient and fast, and the productivity is high; The surface is treated by anodic oxidation, which is corrosion-proof, spray-free, beautiful and elegant, and can improve the added value of products.
Applicable scope: production line, assembly line operating workbench, office partition, screen, industrial fence and various frames, display racks, shelves, mechanical dust-proof sealing covers, etc.
