(Summary description)Aluminum extrusion 7635 manufacturer tells you the process characteristics and advantages and disadvantages of aluminum extrusion molding. Release time: Aluminum extrusion molding is to apply strong pressure to the metal blank placed in the mold cavity (or extrusion cylinder) to force The metal blank produces directional plastic deformation and is extruded from the die hole of the extrusion die to obtain a plastic processing method for parts or semi-finished products with the required cross-sectional shape, size and certain mechanical properties.

1. Aluminum extrusion 7635 manufacturer tells you the process characteristics and advantages and disadvantages of aluminum extrusion molding. Release time: Aluminum extrusion molding is to apply strong pressure to the metal blank placed in the mold cavity (or extrusion cylinder) to force The metal blank produces directional plastic deformation and is extruded from the die hole of the extrusion die to obtain a plastic processing method for parts or semi-finished products with the required cross-sectional shape, size and certain mechanical properties. Aluminum extrusion 7635 manufacturers tell you the classification of aluminum extrusion molding. According to the flow direction of metal plastic deformation, extrusion can be divided into the following categories: Positive extrusion: During production, the flow direction of metal is the same as the movement direction of the punch. Back extrusion: During production , The metal flow direction is opposite to the movement direction of the punch. Compound extrusion: During production, the metal flow direction of a part of the blank is the same as the movement direction of the punch, and the other part of the metal flows opposite to the movement direction of the punch. Radial extrusion: During production, the metal flows The direction of the aluminum extrusion molding process is 90 degrees with the direction of the punch movement.

2. 1. Aluminum extrusion 7635 The manufacturer tells you that during the extrusion process, the extruded metal can obtain a more intense and uniform three-dimensional compression stress state in the deformation zone than rolling forging, which can give full play to the processed metal itself 2. Extrusion can not only produce rods, tubes, shapes, and wire products with simple cross-sectional shapes, but also can produce profiles and tubes with complex cross-sectional shapes; 3. Extrusion has great flexibility and only needs to replace molds. Pressing tools can produce products with different shapes, specifications and varieties on one equipment. The operation of replacing the extrusion die is simple, fast, time-saving and efficient; 4. The precision of the extruded products is high, the surface quality of the products is good, and it also improves The utilization rate and yield of metal materials; 5. The extrusion process has a good effect on the mechanical properties of the metal; 6. The process flow is short and the production is convenient. One-time extrusion can be better than hot die forging or forming rolling. Larger area of ​​the overall structural parts, less equipment investment, low mold costs, and high economic benefits; 7. Aluminum alloy.
3. The aluminum extrusion 7635 manufacturer tells you that gold has good extrusion characteristics and is particularly suitable for extrusion processing. It can be processed through a variety of extrusion processes and a variety of mold structures. Aluminum extrusion 7635 manufacturers tell you the advantages of aluminum extrusion molding 1. Improve the deformability of aluminum. Aluminum is in a strong three-way compressive stress state in the extrusion deformation zone, which can give full play to its plasticity and obtain a large amount of deformation. 2. The comprehensive quality of the products is high. Extrusion molding can improve the structure of aluminum and improve its mechanical properties. After quenching and aging, the longitudinal (extrusion direction) mechanical properties of its extruded products are much higher than similar products produced by other processing methods. Compared with processing methods such as rolling and forging, extruded products have high dimensional accuracy and good surface quality. 3. Wide product range. The aluminum extrusion 7635 manufacturer tells you that extrusion molding can not only produce tubes, rods, and wires with simple cross-sectional shapes, but also solid and hollow profiles with very complex cross-sectional shapes. The cross-section of the product changes in stages and gradually changes along the length. Sectional profiles, many of which have cross-sectional shapes are used. 4. It cannot be formed by other plastic processing methods. The aluminum extrusion 7635 manufacturer tells you that the size range of extruded products is also very wide, from super-large pipes and profiles with a cross-section circumscribed circle diameter of 500-1000mm, to ultra-small precision profiles with a cross-section size like a matchstick.
4. Large production flexibility. The aluminum extrusion 7635 manufacturer tells you that extrusion molding has great flexibility. You can produce products with different shapes, sizes, specifications and varieties on the same equipment only by changing molds, and the operation of changing molds is simple, convenient, and time-consuming. efficient.
5. The process flow is simple and the equipment investment is small. Aluminum extrusion 7635 manufacturers tell you that, compared with piercing rolling, pass rolling and other pipe and profile production processes, extrusion molding has the advantages of shorter process flow, less equipment and less investment. Disadvantages of aluminum extrusion molding 1. The product structure and performance are not uniform. The aluminum extrusion 7635 manufacturer tells you that due to the uneven flow of metal during extrusion (especially serious during forward extrusion without lubrication), the extruded products have uneven surface and center, head and tail organizational properties. 2. The working conditions of the extrusion tools are bad, and the tools and dies are worn out. The billet is in an approximately closed state during extrusion, and the three-way pressure is high, so the mold needs to withstand high pressure. At the same time, the mold is usually subjected to high temperature and high friction during hot extrusion, which greatly affects the strength and service life of the mold. 3. The production efficiency is low. Except for the continuous extrusion method developed in recent years, various conventional extrusion methods cannot achieve continuous production. Under normal circumstances, the extrusion speed is much lower than the rolling speed, and the loss of geometric waste produced by extrusion is large and the yield is low. Summary In recent years, due to the pursuit of miniaturization and light weight in various industries, aluminum and aluminum alloy profiles have been widely used in construction, transportation, electronic appliances, aerospace and other industries. Therefore, the proportion of aluminum extrusion products has also increased rapidly. According to data, aluminum and aluminum alloy products account for more than 70% of extrusion products.
