Aluminum extrusion process characteristics
1. During the extrusion process, the extruded metal can obtain a more intense and even three-direction compression stress state in the deformation zone than the rolling forging, which can give full play to the plasticity of the processed metal itself;
2. Extrusion molding can not only produce rod, tube, shape and line products with simple section shapes, but also produce profiles and pipes with complex section shapes;
3, extrusion molding flexibility, only need to replace the mold and other extrusion tools, you can produce different shapes and specifications and varieties of products on a single equipment, replace the extrusion mold operation is simple, quick, time saving, efficient;
4. High precision of extrusion products, good surface quality of products, and improved utilization rate and yield of metal materials;
5. The extrusion process has a good influence on the mechanical properties of the metal;
6. Short process flow, convenient production, one extrusion can or than hot die forging or forming rolling method of larger area of the overall structural parts, less equipment investment, low mold cost, high economic benefits;
7, aluminum alloy has good extrusion characteristics, especially suitable for extrusion processing, can be processed through a variety of extrusion technology and a variety of mold structure.
