Precautions for aluminum die casting during die casting
Publish Time: 2024-07-22
In the aluminum die casting industry, people who make extruded aluminum profiles know that it is not worthwhile, should not happen, and can be prevented if the profile is scrapped in the case of bending! So, how to reduce or prevent scrapping due to bending!
1. Surface treatment and shelf: After aging, the hardness of the blank is qualified, and the profile is not so easy to bend, but it is still necessary to pay attention when putting it on the shelf. When lifting the material at both ends, try to avoid strong up and down shaking. Strong shaking will also cause certain bending to the aged aluminum profile.
2. Extrusion framing: This link is also very important. After sawing the fixed length, the aluminum profile needs to be framed. At this time, the framer should pay attention to whether the material is large or small, with a tube or pulled out of a flat mold. Generally speaking, it is not easy to bend when lifting the two ends of large materials and materials with tubes for framing, but it is easy to bend when lifting the two ends of small materials and materials pulled out of flat molds. At this time, the materials should be lifted from the two ends to the center for framing. However, some profiles cannot be done even in this way, such as blinds, window pieces, glands, etc. These materials must be placed on the aged profiles and then lifted into the frame.
3. Extrusion straightening: Straightening is a very serious link in the bending of profiles. The straightening worker must pay attention to the strength used for straightening. Too much force may cause deformation, closing, orange peel, etc. of the profile. Too little force will cause the profile to be unstraightened and bend.
