The first process of aluminum extrusion is melting and casting. After batching, smelting, and casting, it is finally made into a "round casting rod", which is a common raw material for aluminum profiles. Then, according to the product cross-section of the aluminum profile, the mold is designed and manufactured. The extruder is used to extrude the heated round casting rod from the mold. There is an air-cooled quenching process and subsequent artificial aging process during extrusion To complete heat treatment strengthening.
The aluminum rod is blank in the extrusion process. The aluminum rod for extrusion can be solid or hollow, usually a cylinder, and the length is determined by the extrusion ingot.
Aluminum rods are usually formed by casting, and some are forged or powder forged. It is usually cut by adjusting the alloy composition of the aluminum alloy bar. The aluminum rod is generally heated to 450 degrees by a heating furnace and then sent to the molding. Finally, about 10% of the aluminum rod is left in the ingot cylinder.
Aluminum Extrusion Advantages:
1. Improve the deformability of metal
The extrusion ratio of pure aluminum can reach 500, the extrusion ratio of pure copper can reach 400, and the extrusion ratio of steel can reach 40-50. For some low-plasticity and difficult-to-deform metals and alloys that are difficult to process or even cannot be processed by other methods such as rolling and forging, even brittle materials such as cast iron can be processed by extrusion.
2. High comprehensive product quality
Extrusion deformation can improve the structure and mechanical properties of metal materials, especially for some aluminum alloys with extrusion effects. After quenching and aging, the longitudinal (extrusion direction) mechanical properties of the extruded products are much higher than other processing methods. Production of similar products
3. Wide range of products
Extrusion processing can not only produce tubes, rods, and wires with simple cross-section shapes, but also can produce solid and hollow profiles with very complex cross-section shapes, and the cross-section profiles of products that change in stages and gradually change along the length. The range of sizes is also very wide, from ultra-large pipes and profiles with a diameter of 500-1000mm outside the cross-section to ultra-small precision profiles with a cross-section-like size.
