Aluminum is a metal material with a large amount of use and a wide range of applications among non-ferrous metals, and its application range is still expanding. The advantages and characteristics of aluminum are as follows: 1. Low density. The density of aluminum is about 2.7g/cm3. Its density is only 1/3 of that of iron or copper. 2. High plasticity. Aluminum has good ductility, and can be made into various products through extrusion, stretching and other pressure processing methods. 3. Corrosion resistance. Aluminum is a highly electronegative metal, and a protective oxide film will be formed on the surface under natural conditions or anodic oxidation, which has much better corrosion resistance than steel. 4. Easy to strengthen. The strength of pure aluminum is not high, but its strength can be improved by anodizing. 5. Easy surface treatment. Surface treatment can further enhance or change the surface properties of aluminum. The aluminum anodizing process is quite mature and the operation is stable, and it has been widely used in the processing of aluminum products. 6. Good electrical conductivity, easy to recycle.

The radiator we often use is made of aluminum, and its main function is to dissipate heat. Because aluminum profile materials are cheaper in the market and have better heat dissipation effects, it is a better choice to use aluminum profiles as heat sinks. Commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is expensive, difficult to process, too heavy (many pure copper radiators exceed the weight limit of the CPU), small in heat capacity, and easy to oxidize. the However, pure aluminum is too soft to be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than copper. Some radiators take their own advantages, and a copper plate is embedded on the aluminum alloy radiator base. The aluminum profile radiator has the characteristics of beautiful appearance, light weight, good heat dissipation performance, and good energy-saving effect. The surface of the processed aluminum profile radiator is anodized for surface treatment to increase the corrosion resistance, wear resistance and aesthetics of the aluminum profile. Due to its superior performance, aluminum radiators are widely used in: machinery, automobiles, wind power generation, construction machinery, air compressors, railway locomotives, household appliances and other industries.

The production process of aluminum profiles mainly includes three processes: casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder coating, wood grain transfer printing, etc.). 1. Melting and casting is the first process of aluminum production. The main process is: (1) Ingredients: According to the specific alloy grades that need to be produced, calculate the addition amount of various alloy components, and reasonably match various raw materials. (2) Smelting: The prepared raw materials are put into the melting furnace for melting according to the process requirements, and the impurities and gases in the melt are effectively removed by means of degassing and slag removal and refining. (3) Casting: Under certain casting process conditions, the smelted aluminum liquid is cooled and cast into round casting rods of various specifications through the deep well casting system. 2. Extrusion: Extrusion is a means of profile forming. First, design and manufacture the mold according to the cross-section of the profile product, and use the extruder to extrude the heated round cast rod from the mold. The commonly used grade 6063 alloy also uses an air-cooled quenching process and a subsequent artificial aging process during extrusion to complete heat treatment strengthening. Different grades of heat treatable strengthening alloys have different heat treatment systems. 3. Coloring (here we mainly talk about the oxidation process) Oxidation: Extruded aluminum alloy profiles have poor surface corrosion resistance, and surface treatment must be performed through anodic oxidation to increase the corrosion resistance, wear resistance and appearance of the aluminum profile. The high-compartment aluminum profiles produced by Jiange High-compartment Aluminum Profile Factory are almost all oxidized. Its main process is: (1) Surface pretreatment: Use chemical or physical methods to clean the surface of the profile to expose the pure substrate, so as to obtain a complete and dense artificial oxide film. Mirror or matt (matt) surfaces can also be obtained by mechanical means. (2) Anodic oxidation: After surface pretreatment, under certain process conditions, anodic oxidation occurs on the surface of the substrate to form a layer of dense, porous, and strong adsorption AL203 film. (3) Pore sealing: the film pores of the porous oxide film formed after anodic oxidation are sealed, so that the anti-pollution, corrosion resistance and wear resistance of the oxide film are enhanced. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film pores, which can make the surface of the profile appear many colors other than the original color (silver white), such as: black, bronze, Golden yellow and stainless steel color, etc.

Mold is known as the "mother of manufacturing industry", and it is one of the most important supporting equipment in the aluminum processing industry. Its accuracy and stability determine the quality of aluminum profile products to a large extent. According to statistics, the market size of China's mold industry has fluctuated in recent years. From 2016 to 2021, the growth rate of China's mold industry market will be between -2% and 12%. In 2020, the market size of China's mold industry will be 308.92 billion yuan. The market size of the mold industry was 326.609 billion yuan, a year-on-year increase of 5.7%. With the dual upgrading of consumption and manufacturing, and the arrival of the "Made in China 2025" era, it can be seen that the mold industry is facing new opportunities and challenges, and the requirements for molds of products in various industries are also increasing. For the mold itself, the refinement of its manufacturing, efficiency and quality assurance, utilization rate and efficiency of manufacturing and processing equipment all directly determine the market competitiveness. So, what are the future development trends of the mold industry? 1. Precision Precision casting excellent products! Usually divided according to the machining accuracy, machining can be divided into three stages: general machining, precision machining, and ultra-precision machining. At present, precision machining refers to the processing technology with a machining accuracy of 1~0.1µ;m and a surface roughness of Ra0.1~0.01µ;m. and surface conditions; the second is processing efficiency, some processing can achieve better processing accuracy, but it is difficult to obtain high processing efficiency. For molds, dimensional accuracy is the most important factor in manufacturing high-precision, high-quality, high-tech products. 2. Intelligence and digitization With the development of information and digital technology, the intelligentization of molds has attracted people's attention and attention. Intelligentization is an important guarantee for improving efficiency, including various automation equipment that cooperates with mold production, mainly the popularity of manipulators and robots, and the interior of molds. The intelligence level of standard parts has been improved, etc. The intelligence and networking of molds include various aspects, such as: mold design, mold manufacturing system, mold forming simulation analysis, mold operation process, mold enterprise management, and mold market. The production of products with intelligent molds can further improve product quality and production efficiency, save more materials, realize automated production and green manufacturing. Therefore, although the total amount of smart molds is not large at present, it represents a new development direction of mold technology, and will play an increasingly important role in the adjustment of industry product structure and the transformation of development methods. 3.
