Aluminum profile encountered problems and solutions

Update time : 2022-11-04 18:03:58

1. The temperature of aluminum profile kneading is too low, the kneading speed is too slow, the exit temperature of the profile in the kneading machine cannot reach the solution temperature, and the solution strengthening effect cannot be achieved;

Solution: Reasonably control kneading temperature and kneading speed, so that the exit temperature of the profile in the kneading machine is kept above the solution temperature.

2. There are few fans at the exit of the aluminum profile, and the air volume is not good, which leads to slow cooling speed. The aluminum profile cannot be reduced to below 200℃ in the shortest time, so that the coarse magnesium silicate precipitates prematurely, which reduces the solid solution phase and affects the mechanical function of the profile after heat treatment;

Solution: Enhanced air cooling conditions, where conditions factory equipment atomization cooling equipment, in order to achieve the 6063 alloy cooling gradient of the requirements.

3. Ingot composition is not qualified, and the content of magnesium and silicon in ingot cannot meet the standard requirements;

Solution: Strengthen the quality management of ingot.

4. The ingot was not homogenized, so that the precipitated magnesium silicate phase in the ingot arrangement could not be re-dissolved in a short time during kneading, resulting in insufficient solid solution and affecting the product function;

Solution: Homogenize the ingot.

5. Improper aging process, poor hot air circulation or incorrect location of thermocouple equipment, resulting in insufficient aging or over-aging;

Solution: Reasonably determine the aging process, correct equipment thermocouple, and correct placement of aluminum profiles to ensure smooth hot air circulation.

How to do a good job of cleaning industrial aluminum profiles?

Jul .17.2023

Spraying cleaning method of industrial aluminum profiles is widely used, because of complex equipment, high process requirements, poor cleaning effect, then how to better do spray cleaning of industrial aluminum profiles?

Aluminum extrusion profile six places are required during the stretching process

Jul .07.2023

The aluminum extrusion profile must be cooled to below 50 degrees before stretching. If the temperature is too high, stretching will not only burn the human body, the hair belt, but also expose absolute waste products such as bending, twisting, and poor performance before and after aging, because the stress in the aluminum alloy profile can not be completely eliminated.

Curtain wall aluminum profile purchase mainly see where?

Jul .06.2023

Appearance quality of curtain wall aluminum profile: the surface of anodic oxide film is not allowed to have electrical burns, oxide film falling off and other defects; Electrophoretic, powder, fluorocarbon profile paint film should be uniform, neat, smooth, do not allow wrinkles, cracks, bubbles, flow signs, inclusions and paint film fall off and other defects, but allow local film within 80 mm at the end of the profile.
