During the extrusion process, 6061 alloy aluminum plate is prone to peeling or bubbles on the surface. Why does peeling or bubbles occur and what should be done?
 

During the extrusion process of 6061 alloy aluminum plate, there are many reasons for the phenomenon of surface peeling or bubbles. The main reason is that the wear of the extrusion cylinder and pad is out of tolerance, resulting in improper size. The presence of oil, water, graphite, etc. inside can easily cause bubbles and peeling during the extrusion of 6061 aluminum plate. When the temperature of the extrusion barrel is too high, the design of the mold hole is unreasonable, and improper cutting can also cause peeling on the extrusion surface of 6061 alloy aluminum plate.
 

There are quite a few methods to eliminate bubbles and peeling caused by the extrusion of 6061 alloy aluminum plate. Firstly, it is necessary to check the tool size to ensure that there is no mismatch in size and the size must be appropriate. Especially for 6061 aluminum plate tools and ingot surfaces, it is necessary to maintain cleanliness, smoothness, and dryness, and to regularly inspect equipment and instruments to avoid overheating. In order to avoid peeling on the extruded surface of 6061 alloy aluminum plate, we need to choose a large and reputable manufacturer of 6061 aluminum plate. It is important to undergo reasonable design, strict operation, correct cutting of residual materials, and exhaust. Especially when making 6061 alloy aluminum plate, strict adherence to process procedures and various systems is essential.
