Problems solved by technology

The aluminum alloy profile used for the mobile phone panel is a plate. In the production process, there are often problems such as insufficient hardness of the profile, poor temperature and time control
The influencing factors are: the existing extrusion speed is mostly 25-30m / min, if the extrusion speed is too fast, it is easy to generate more frictional heat, so that the outlet temperature of the profile is higher than 530°C, which is prone to tearing and affects the quality of the profile. Surface quality, resulting in waste; then usually use air-cooling and quenching treatment, because this kind of profile is thick material, air-cooling and quenching can not quickly cool the extruded profile, thus affecting the hardness and quality of the profile, easy generate waste

Description

technical field [0001] The invention belongs to the technical field of aluminum alloys, and in particular relates to an extrusion process of aluminum alloy profiles used for mobile phone panels. Background technique [0002] With the development of the times, mobile phones have gradually become an indispensable thing for people. Because aluminum alloy profiles have the advantages of good corrosion resistance, non-ferromagnetism, machinability, formability, and recyclability, many mobile phone panels are currently made of aluminum alloy profiles. [0003] The production process of aluminum alloy profiles mainly includes three processes: casting, extrusion and surface treatment. Among them, extrusion is the means of profile forming. Extrusion is to design and manufacture the mold according to the section of the profile product, use the extruder to extrude the heated round cast rod from the mold, and then go through the quenching process and artificial aging process to comple...
