How to avoid the low hardness of industrial aluminum profile

1. Measuring the ingot temperature before aluminum profile extrusion.

2. Setting and controlling the temperature of the time-age furnace: Usually, there is a certain error between the time-age furnace temperature and the time-aging furnace table display temperature, and when setting the table temperature, it should be set according to the actual temperature of the furnace, and pay close attention to the fluctuation of the temperature of the time-age furnace

3. Put the other 6000 series alloy and 6063 aluminum alloy into different furnace. Because of the production reasons have to put them into the same furnace and aging, to use the special alloy process to time-up.

4. To strictly in accordance with the requirements of the process to time-up, insulation time to be appropriate, to prevent the lack of aging or over-aging resulting in insufficient hardness.

5.The aluminum profile extrusion in the frame can not be too tight, there should be an interval between the materials,especially then non ventilated small material,thick material.Pipe material and small material, plate material in to the same frame, the pipe materia should be at the bottom. It is conducive to the time cycle of air delivery.
