1. During the extrusion process, the extruded metal can obtain a more intense and uniform three-direction compressive stress state in the deformation zone than the rolling forging, which can fully exert the plasticity of the processed metal itself;
2. Extrusion can not only produce rods, tubes, profiles and wire products with simple cross-section shapes, but also produce profiles and pipes with complex cross-section shapes;
3, extrusion molding flexibility, only need to replace the extrusion tools such as mold, you can produce a variety of shapes and varieties of products on a single device, the replacement of the extrusion mold operation is simple, fast, time-saving, efficient;
4. The precision of the extruded product is high, the surface quality of the product is good, and the utilization rate and yield rate of the metal material are also improved;
5. The extrusion process has a good influence on the mechanical properties of the metal;
6. The process is short, the production is convenient, and the overall structural parts with larger area than the hot die forging or forming rolling can be obtained in one extrusion, the equipment investment is low, the mold cost is low, and the economic benefit is high;
7. Aluminum alloy has good extrusion properties, especially suitable for extrusion processing, and can be processed through various extrusion processes and various mold structures.
