On the one hand, the quality of aluminum profiles comes from the level of aluminum in its own raw materials, on the other hand, it comes from the technical control in the production process, that is, in the production process of each link has a timeliness of control.

　　Ageing process in aluminium profile production:

　　1. Common curtain wall profiles, common door and window profiles, industrial profiles must be aged in the same aging furnace. The temperature in the furnace should be controlled in the range of 195 ° C ± 5 ° C, after the furnace immediately open the blower 20 minutes cooling, quality inspector inspection hardness.

　　2. Insulated curtain wall profiles and insulated door and window profiles must be aged in the same aging furnace. The temperature in the furnace should be controlled in the range of 180 ° C ± 3 ° C, after the furnace immediately open the blower 20 minutes cooling, quality inspector inspection hardness.

　　3. If the thermal insulation profile is not full of the furnace, 1-2 frames of ordinary profile (the wall thickness is less than 2.0 mm) can be put in the same furnace aging, aging process according to the thermal insulation profile process.

　　4. The end of the profile and the air inlet should be controlled within 80-100mm.

　　5. When the temperature in the furnace reaches the required temperature, the aging workers use the glass tube thermometer to measure the actual temperature in the furnace every 30 minutes, and make the original record.

　　Only strict control of the above-mentioned each effective link, in order to ensure the factory's aluminum profile product performance and quality.
