Operating procedures for aging process of aluminum profiles

West Aluminum - West Aluminum Industry Telecom: Operating procedures for aging process of aluminum profiles

一、 Requirements for aluminum profile framing:

1. Ordinary curtain wall profiles, ordinary door and window profiles and industrial profiles must be installed in the same frame respectively.

2. Thermal insulation curtain wall profiles and thermal insulation door and window profiles must be installed in the same frame respectively.

3. It is not allowed to mix thermal insulation profile and common profile in the same frame.

4. Each frame of profile must be filled with 5mm below the frame surface, and each row of profile should be separated by a cushion strip to ensure that each profile has hot air circulation in place to play the heating effect.

5. Flat die profiles with wall thickness ≥ 4mm are not allowed to overlap (only one piece per layer is allowed).

6. 80mm ventilation channel must be reserved in the middle of each frame for small materials with wall thickness ≥ 2mm.

二、 Aging process:

1. Common curtain wall profiles, common door and window profiles, and industrial profiles must be aged in the same aging furnace. The temperature in the furnace shall be controlled within the range of 195 ℃ ± 5 ℃. After reaching the temperature, the furnace shall be kept for 3 hours, and the fan shall be opened for 20 minutes to cool down immediately after the furnace. The quality inspector shall inspect the hardness.

2. Thermal insulation curtain wall profiles and thermal insulation door and window profiles must be aged in the same aging furnace. The temperature in the furnace shall be controlled within 180 ℃ ± 3 ℃. After reaching the temperature, the furnace shall be kept for 3 hours, and the fan shall be opened immediately after the furnace is cooled for 20 minutes. The quality inspector shall inspect the hardness

3. If the aging heat-insulating profile is not enough in the furnace, 1~2 frames of ordinary profile (wall thickness below 2.0mm) can be put in the same furnace for aging, and the aging process shall be executed according to the heat-insulating profile process.

4. When lifting the material into the furnace, the end of the profile and the air guide shall be controlled within 80~100mm.

5. When the temperature in the furnace reaches the temperature required by the process, the aging worker shall measure the actual temperature in the furnace with a glass tube thermometer every 30 minutes and make original records.
