Aluminium profile basically does not have national standard not standard of say, but China has special industry standard to architectural aluminium profiles, basically make a requirement to the thickness of profile, material. The products produced by every aluminum profile production enterprises are basically the same, but there are differences in the specific structure.But like the more general series, like GB 50, GB 868, GB 90, these are basically the same. 80 series and 60 series refer to the width of the frame of the aluminum alloy profile is 80 mm and 60 mm respectively. According to the processing technology of extruded profiles, they can be divided into oxidation, electrophoresis, electrostatic powder spraying, fluorocarbon spraying, that is to say, different coating methods.At present, 85% of the consumption in the market is electrostatic powder spraying profiles, namely color aluminum profiles.

Industrial aluminum profile in current situation, the demand for both auto, machinery, protection, rail mounting, this will naturally think of the cost and resource use of dual problem, so how to improve the yield of industrial aluminum extrusion become the urgent matter, a lot of measures to improve productivity, this article mainly talk about some relatively more concrete and practical two measures. To increase the output of extrusion products, advanced equipment, high-quality workers, modern scientific management plays a vital role.In our country, the existing more than 2500 industrial aluminum extrusion machine, reach the international level of around 25 sets, only about 1%, aluminum extrusion industry in China is in the stage of structural adjustment, should avoid to low levels of repeat the introduction and development, a transformation of the existing value of industrial aluminum extrusion machine best transformation into modern high levels of industrial aluminum extrusion machine. In general, if there is no unscheduled downtime, then the maximum output is primarily determined by the extrusion speed, which is subject to four factors, three of which are fixed and one of which is variable.The first factor is the extrusion pressure of the industrial aluminum extruder. The extrusion pressure with large extrusion pressure can be extruded smoothly when the billet temperature is low.The second factor is the mold design. The friction between the metal and the mold wall during extrusion can usually increase the temperature of the aluminum alloy passing through by 35 ~ 62℃.The third factor is the characteristics of the aluminum alloy being extruded, which is an uncontrollable factor limiting the extrusion speed. The outlet temperature of the aluminum profile should not exceed 540℃ in general, otherwise, the material surface quality will decline, the mold marks will be significantly aggravated, and even aluminum adhesion, gravure, micro cracks, tear and so on.The last factor is temperature and how much control it has.

The material of aluminum extrusion profile, aluminum itself is a kind of material corrosion resistance is strong, but met after oxygen on the surface of aluminum form 3 oxidation 2 aluminium oxide, so after a long time will slowly lifted his KangFuXing and mo resistance, and aluminum is very sensitive to acid substances, encounter acid can damage the surface of the aluminum group layer, so we need to again after oxidation treatment, add a layer of protective film on the surface. Strengthen KangFuXing surface, aluminum profiles after surface anodized, its corrosion resistance, hardness, wear resistance, insulation and heat resistance were increased significantly.The most anodized metal is aluminum.Anodic oxidation of aluminum tubes is generally carried out in an acidic electrolyte with aluminum as the anode.In electrolysis, the anion of oxygen interacts with aluminum to produce an oxide film.The initial formation of this film is not fine enough, although there is a certain resistance, but the electrolyte of negative oxygen ions can still reach the surface of the aluminum oxide film continues to form.As the film thickness increases, the resistance also increases, thus the electrolytic current decreases.At this point, the outer oxide film in contact with the electrolyte is chemically dissolved.When the rate of formation of oxide on the surface of aluminum gradually balances the rate of chemical dissolution, the maximum thickness of the oxide film under this electrolytic parameter can be achieved.The outer layer of anodic oxidation film of aluminum is porous and easy to absorb dyes and colored materials, so it can be dyed and enhance its decorative effect.The corrosion resistance and wear resistance of oxide film can be further improved after being closed by hot water, high temperature steam or nickel salt.In addition to aluminum, industrial surface anodized metals include magnesium alloy, copper and copper alloy, zinc and zinc alloy, steel, cadmium, tantalum, zirconium and so on.

Solar mounting system is a support designed for placing, installing and fixing solar panels in solar photovoltaic power generation system. At present, common photovoltaic bracket materials in photovoltaic power generation projects include ordinary steel, stainless steel and aluminum profiles, and aluminum profiles are most widely used. Aluminum profile has the advantages of light weight, corrosion resistance, simple structure, easy installation and so on.So many solar pv stands and fasteners now choose aluminum profiles. Industrial aluminum does not need to be welded, directly with the corresponding accessories can be assembled, the period is short, the customer can be assembled on its own. Industrial aluminum profiles have a variety of specifications, can be used in different occasions in the demand, according to the production requirements for flexible customization, in line with the needs of personalized customization. Fujian Shuangheng Group is specialized in the production of industrial aluminum profiles, solar mounting system, solar roof supports, solar carport stureture frames, ground screws, etc.. We provide OEM, ODM services.

Industrial aluminum (alloy) profile is widely used, strong versatility, it is known for environmental protection, easy assembly and disassembly, saving time and money.No welding, accurate size, easy to change structure;Assembly work is convenient and fast, high productivity;The surface is treated by anodic oxidation, with high finish, anti-corrosion, no spraying, beautiful and generous, which can improve the added value of the product. Now the price of industrial aluminum profile market is more chaotic, the price gap is very far.The main factors leading to different prices are: Raw material: In order to save the cost of using recycled aluminum, the flatness and surface defects of the produced profiles are seriously exceeding the standard, and even cause the profiles to break. Fujian Shuangheng Group only USES A00 standard aluminum. Homogeneous: The traditional process can not guarantee the uniform distribution of alloy composition, which is easy to cause surface defects and unstable product batches.However, the early investment of homogeneous rod production is higher, and the later production cost will also be higher, so many small manufacturers are unable or unwilling to invest. Fujian Shuangheng Group industrial aluminum profile is produced by homogeneous bar production process, which reduces the die extrusion ratio and extrusion pressure.Improve the surface quality and mechanical properties of finished products. Oxidation: In order to save costs, reduce oxidation time and steps, resulting in substandard oxide film thickness, easy to cause surface damage of profiles, especially in processing, assembly and logistics links. Fujian Shuangheng Group adopts frosted oxidation, the surface is free from defects, the film thickness exceeds national standard by 30%, and the profiles are as bright and clean as new in 20 years. Testing equipment: In order to reduce labor costs, equipment maintenance costs, and technical costs, many enterprises do not have a full set of equipment or equipment itself precision is not high and not regular maintenance, let alone professional personnel and strict procedures.Low product cost, resulting in vicious bidding industry, customers found after buying unsatisfactory. Fujian Shuangheng Group spectrometer and tension, end face, hardness, film thickness tester and other imported series of complete testing equipment, 12 strict testing procedures, professional testing personnel. Suggestion: Choose the main aluminum suppliers Choose the main supplier of aluminum, are generally not engaged in this industry more than 10 years, especially the processing experience of the factory, has very rich practical experience, the product quality and performance have good understanding and master, can according to the different field of application, issue a reasonable framework scheme design, choose a convenient and practical way of fitting connection, recommend to customer demand for a good cost performance products.

At high temperature, the aluminum profile has high plasticity and low resistance, coupled with the intensified atomic diffusion process and complete recrystallization, which is beneficial to the improvement of the structure.Thermal deformation is the most effective way to change the as-cast structure of aluminum profiles when the 3-direction compressive stress is dominant.The following favorable changes of as-cast microstructure can be obtained with appropriate deformation. (1)The general thermal deformation is accomplished through repeated deformation of multiple steps.As both hardening and softening processes occur simultaneously in each strand.The large columnar grains were broken by deformation of industrial aluminum profiles.At the same time, it can also make some small cracks can be healed. (2)Due to the hydrostatic pressure in the stress state, bubble welding can be promoted in the as-cast structure, shrinkage cavity compaction, loose compaction and densification can be changed into a relatively compact structure. (3)Due to the enhanced thermal motion ability of high temperature atoms, under the action of stress, the free diffusion and heterdiffusion of atoms are conducive to the relative reduction of the ingot chemical composition non-uniformity. By thermal deformation, the ingot structure improves the deformed (or processed) structure, resulting in higher density, uniform fine equiaxial grains, and more uniform chemical composition, thus significantly improving the plasticity and resistance index.
