The  quality of aluminum profile, on the one hand based on the raw materials, on the  other hand based on 

production process of its technical control. But all aluminum profiles need to pay  attention to temper and

control the temper in the production process.

The Temper Technique in Aluminum  Production  Process:

1.      The  general curtain wall profiles, doors and windows profiles and industrial  profiles must be tempered 

in the same aging oven, and the temperature controls  in the range of 195 ℃ ± 5 ℃. After reaching the tem-

perature 3 hours, the profile will be discharged. The air blower should be cooled for 20 minutes immediately 

after the discharge. The quality  inspectors examine the hardness of profile.

2.      Curtain  wall insulation profiles, insulation doors and windows profiles must be  tempered in the same aging 

oven, and the temperature controls in the range of 180℃ ± 3 ℃. After reaching the temperature after 3 hours, 

the profile will be discharged. The air blower should be cooled for 20 minutes immediately after the discharge. 

The quality  inspectors examine the hardness of profile.

3.      If  the aging oven also has the blank space, we can put 1 ~ 2 box ordinary profiles(wall thickness below 

2.0mm) in it, the temper technique based on the insulation profile’s technique.

4.      When hanging  materials into the aging oven, the distance between the end of profile and Guide  tuyere 

need to control in the range of 80 ~ 100mm.

5.      The  temperature of the aging oven reaches the requirements of   temperature, the workers  need to 

measure the actual temperature with a glass tube thermometer and make  the original record.

Only control the every step strictly can  we ensure the performance and quality of aluminum profile.
