1. The mixing of metal content is unreasonable, showing differences in hardness. For 6061 aluminum plates, most of them are composed of materials. The alloy composition inside is different, and there will be some differences in product functions. So regarding metal materials It is said that scientific and reasonable deployment will bring very good products and improve the performance of the products.
2. The difference in water temperature when the product is cooled. Generally, cooling water has a certain influence on the forming of 6061 aluminum plates. It can cool and shape the macromolecular chains of the profile in time to achieve excellent shaping effects.
3. Regarding the reduced function caused by poor collection of shunt ribs. In this case, the length of the confluence of ribs and outer surface, ribs and ribs should be appropriately increased, or the compression ratio should be increased to deal with the change in die pressure. The flow resistance can be adjusted by changing the length of the straight section of the die: in the mold design stage You can choose different compression ratios to change the extrusion pressure. But you must pay attention to the compression ratio of the machine head to be consistent with the compression ratio of the extruder screw. You can also change the melt by changing the formula, adjusting the extrusion technology parameters, and adding a porous plate. Amount of pressure
4. Uneven material discharge from the die results in inconsistent wall thickness and perhaps inconsistent density of the profile. This also results in differences in the mechanical functions between the two surfaces of the profile. As for non-standard profiles such as wall panels, I won't go into detail here.
5. The cross-section design of the die is unreasonable, especially the distribution of internal ribs and the handling of the interface angle, which will cause stress concentration. It is necessary to improve the design and eliminate right angles and acute angles at the interface.
6. In the storage environment of 6061 aluminum plates, usually this 6061 aluminum plate will be subject to certain corrosion, because aluminum is an unstable metal, and if there are problems with the metal surface, it will cause certain changes.
