Reasons for unqualified production of aluminum profiles in LED tube housings

The main reasons for the unqualified production of aluminum profiles of LED tube housing are as follows:

① When the extrusion temperature of the aluminum profile is too low, the extrusion speed is too slow, the outlet temperature of the profile at the extrusion machine cannot reach the solid solution temperature, and the solid solution strengthening effect cannot be achieved;

②There are few fans at the outlet of the profile, and the air volume is not enough, resulting in a slow cooling rate, which cannot make the profile drop below 200 °C in the shortest time, so that the coarse Mg2Si precipitates prematurely, thereby reducing the solid solution phase and affecting the profile after heat treatment. Mechanical behavior;

③The composition of the ingot is unqualified, and the content of Mg and Si in the ingot does not meet the standard requirements;

④The ingot is not homogenized, so that the Mg2Si phase precipitated in the ingot structure cannot be re-dissolved within a short time of extrusion, resulting in insufficient solid solution and affecting product performance;

⑤ Improper aging process, poor hot air circulation or incorrect installation position of thermocouples, resulting in insufficient aging or over aging.
