After the aluminum rod is heated, it is followed by the extrusion process. In the process of aluminum alloy extrusion products, defects that are visible to the naked eye (such as bending, deformation, short strips and lines, etc.) and invisible defects (such as adsorption particles).
If you do not pay attention to observing and summarizing the reasons for the defects in the production process, and solve the problems in time, the appearance of the aluminum profile products produced is not good-looking, and it is easy to cause scrapping if you are not careful, which will bring unnecessary losses to the enterprise.
Let's first take a look at the problems that are prone to occur when aluminum profiles are extruded, such as short strips, bending, and scribing defects. The reasons are as follows:
1. The size between the aluminum extrusion cylinder and the aluminum extrusion pad is not matched, and the poor die hole causes the aluminum metal particles to be pressed into short strips.
2. Therefore, when choosing a mold, you must choose the appropriate size of the mold pad and support pad. If the size is not appropriate, you can install it appropriately.
3. The aluminum extrusion die is not replaced in time, the use time is too long, the hardness is not enough, and the extruded profile is elastic and easy to bend.
4. Affected by extrusion speed and extrusion temperature,
5. If the extrusion speed is too fast and the extrusion temperature is too high, the flow speed of the profile will also be accelerated, and the degree of deformation of the mold will increase.
6. The speed of metal flow is accelerated, and the deformation resistance is relatively weakened, which is easy to cause aluminum sticking, increase the roughness of the surface of the tool and die, and form a scribe on the surface of the profile.
7. Lightly affects the appearance, the quality of the aluminum profiles produced is not good enough, and in severe cases, it is directly scrapped.
8. These defects have some common characteristics: the surface of aluminum alloy extrusion products is white, distributed vertically and has a certain concentration, intermittently or scattered, and the tail is more than the front, that is, the color is gray-black after oxidation, which is serious. Affects aesthetics and quality.
