How to control the hardness of industrial aluminum profiles in production?

Update time : 2022-09-07 19:01:00

Industrial aluminum profile in the production and processing, how to control the hardness is a key step, a little unqualified, will bring trouble to customers, so how to solve the industrial aluminum profile hard too low?

1, aluminum aging furnace temperature setting and control: usually, aging furnace temperature and aging furnace surface temperature will have a certain error, set the furnace surface temperature according to the actual temperature of the furnace to set, and pay close attention to the aging furnace temperature fluctuations.

2. Aluminum aging: aging should be carried out in strict accordance with the process requirements, and the holding time should be appropriate to prevent insufficient aging or over-aging resulting in insufficient hardness.

3, aluminum extrusion frame can not be too dense, there should be a gap between the material and the material, especially not ventilated small material, thick material interval is larger, tube material and small material, sheet material together in a frame, tube material put below this helps to circulate air supply.

4. Before aluminum profile loading, other special alloys of 6XXX and ordinary 6063 alloy should be aging separately. When aging with the same furnace is indeed required for production reasons, the process of special alloy should be used for aging. Extruded aluminum profile, without aging before the hardness is low, can not be used as a finished product, therefore, generally speaking, must be through aging to improve the strength.
