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.

What are the methods of identifying the quality of motor housing aluminum extrusions?

Mar .31.2023

With the widespread use of aluminum profiles, motor housing aluminum extrusions processing manufacturers are also increasing, but because of the uneven processing technology of various manufacturers, the quality of processed products also have concave and convex.

What are the polishing methods of motor housing aluminum extrusions?

Mar .30.2023

Motor housing aluminum extrusions are often inseparable from polishing if they want to achieve smooth or mirror effect. Its grinding refers to the use of mechanical, chemical or electrochemical action, reduce the roughness of the workpiece surface, make the surface bright and smooth processing method.

Spray curing treatment of motor housing aluminum extrusions

Mar .29.2023

Three spraying layer generally need two curing, motor housing aluminum extrusions into the hardening furnace treatment, hardening temperature is generally between 180℃-250℃, hardening time for 15-25 minutes, different fluorine coating manufacturers according to their own paint to provide the best temperature and time.

How to protect the appearance of motor housing aluminum extrusions?

Mar .28.2023

The appearance of motor housing aluminum extrusions is most easily damaged during the turnover of many processes.
