Photovoltaic solar aluminum profiles Aluminum profiles are recognized as an eco-friendly and highly durable material. Due to their lightweight, corrosion resistance, excellent thermal conductivity, high strength, and ease of transportation and installation, they are commonly used in the manufacturing of brackets and frames for photovoltaic (PV) modules. This specific type of aluminum profile, widely utilized in the solar energy sector, is referred to as photovoltaic aluminum profiles. In an era where the scarcity of non-renewable energy sources like coal and oil poses significant challenges to global economic development, more countries are implementing "Solar Initiatives" to harness solar energy resources and seek new drivers for economic growth. Solar energy photovoltaics are one of the seven key emerging industries prioritized for development in our country. The rapid growth in the photovoltaic power generation sector, both in China and internationally, has significantly increased the demand for aluminum profiles used in solar modules. China holds the largest installed capacity for photovoltaic power globally, with cumulative installed capacity reaching 39,261 MW in 2022, indicating a sustained growth trend. Analyzing the industrial chain: the upstream includes the production of aluminum metal, mainly involving bauxite, alumina, and electrolytic aluminum; the midstream focuses on processes like extrusion, aging, and surface treatment to manufacture industrial aluminum profiles for photovoltaics; while the downstream involves precision processing, turning aluminum profiles into photovoltaic frames and brackets. As of 2022, the CR5 of China’s photovoltaic frame industry reached 48%, with leading enterprises capturing nearly half of the market share. Photovoltaic aluminum alloy profiles are primarily used as frames for solar panels, providing essential support. They serve to fix and seal the solar cell components, enhance structural strength, and facilitate transportation and installation. Aluminum profiles account for approximately 90% of photovoltaic modules, constituting about 8-9% of total costs. Their replacement is challenging, but demand will continue to grow alongside the expansion of the renewable energy photovoltaic sector. More countries are recognizing the importance of developing the photovoltaic industry, leading to a rising demand for photovoltaic aluminum profiles. At Huanan Heavy Industry, we place great emphasis on the production of photovoltaic materials.

                                          What is the typical lifespan of an aluminum extruder? In general, the lifespan of an extruder can range from 5 to 20 years. At Huanan Heavy Industry Technology Co., Ltd., the aluminum extruders we produce have a minimum lifespan of 10 to 20 years, with an average lifespan of around 15 years. However, the exact lifespan varies depending on several factors, such as the type of materials being processed, production volume, extrusion time, machine maintenance, equipment manufacturing quality, and the operating environment. Therefore, it's difficult to provide a specific lifespan for an Aluminum extrusion machine. If the materials being processed cause significant wear on the cutting edge of the Aluminum extrusion machine , or if there is high production volume and extended continuous operation, the extruder's lifespan may be shorter. Additionally, if the extruder is not properly maintained and serviced in a timely manner, or if the working environment is harsh, its lifespan could also be affected.   To extend the lifespan of an Aluminum extrusion press, it is essential to choose reliable, high-quality equipment, ensuring the manufacturing quality and design technology meet standards. At the same time, the machine should be used correctly, following the guidelines in the user manual, with regular inspections and maintenance carried out. Parts should be replaced, repaired, or serviced promptly. Moreover, it is important to manage the equipment's working environment, ensuring the machine is operating under favorable conditions to prevent external factors from negatively affecting the extruder.    

When the Aluminum extrusion machine is operating normally, the aluminum forming speed is consistent and uniform. If the extruder is not running smoothly or is unable to extrude aluminum profiles, it is likely due to the following reasons: 1，Low Aluminum Billet Temperature: If the aluminum billet's temperature is too low and does not reach the required extrusion temperature, it can cause difficulties. The billet temperature should be maintained between 400-540°C (for 6xxx series aluminum alloys), with an optimal range of 470-500°C. The required temperature varies for different aluminum profiles. If the temperature is too high, it can cause tearing; if too low, it can reduce extrusion speed because the aluminum needs to be softened. Most of the frictional force generated during extrusion is converted into heat, leading to an increase in temperature. The temperature rise is proportional to the extrusion speed and extrusion pressure. Therefore, to reduce deformation resistance and achieve a high extrusion speed, it is essential to control the extrusion temperature within the desired range. 2，Die Temperature: The die temperature is crucial for both the quality of the extruded profile and the extrusion speed. Typically, the die temperature should not be lower than 426°C before extrusion. If the temperature is too low, it can lead to clogging or even damage the die. Therefore, die temperature is a key factor affecting whether the aluminum profile extruder can achieve high productivity. 3， Extrusion Cylinder Temperature: During the preheating phase of the extruder, it is important to avoid excessive thermal stress and ensure that internal thermal stress is eliminated. The required temperature for the extrusion cylinder varies depending on the type of aluminum billet but generally needs to be above 426°C. 4， Low Extrusion Speed: A low extrusion speed can result in insufficient extrusion pressure, making it difficult to extrude the aluminum profile. In addition to the primary reasons mentioned above, there are other potential causes such as high oil temperature, insufficient lubrication of the extruder, poor die design, and improper aluminum billet length. Our company, Huanan Heavy Industry Technology Co., Ltd., has 30 years of experience in the extrusion industry, producing approximately 160 to 200 Aluminum extrusion machines annually. We have accumulated substantial knowledge and experience in extruder technology. If you would like to discuss extrusion machine-related topics, feel free to contact us at jessica@huananmachine.com.

Influence of extrusion ratio on aluminum extrusion quality The extrusion ratio has a significant influence on the microstructure and mechanical properties of aluminum extrusions. Here's how it impacts these aspects: 1. Grain Structure: lHigher Extrusion Ratios: Tend to produce finer grain structures. This is because the increased flow and deformation can promote more uniform and finer grain refinement. Finer grains generally enhance the strength and toughness of the extruded material. lLower Extrusion Ratios: May result in coarser grain structures. Coarser grains can lead to reduced mechanical properties compared to those with finer grains. 2. Mechanical Properties: lStrength and Hardness: Higher extrusion ratios often lead to improved strength and hardness. The fine-grained structure resulting from higher ratios contributes to better mechanical properties. lDuctility: The impact on ductility can be variable. While higher extrusion ratios typically improve strength, they can sometimes reduce ductility if the metal flow induces internal stresses or defects. lTensile Properties: Extrusions with higher ratios can show better tensile properties due to more uniform microstructure and reduced porosity. However, achieving these benefits requires careful control of other process parameters. 3. Homogeneity: lMaterial Homogeneity: Higher extrusion ratios can lead to more homogeneous material properties along the length of the extrusion. This is because the increased flow helps to distribute alloying elements and reduce segregation. 4. Internal Defects: lInclusions and Voids: Higher extrusion ratios can reduce the incidence of internal defects such as inclusions and voids, as the extrusion process tends to consolidate the material more effectively. However, excessive ratios can introduce new challenges, such as increased risk of billet cracking or die clogging.   In summary, the extrusion ratio is a crucial parameter that influences multiple facets of aluminum extrusion quality. While higher extrusion ratios often enhance mechanical properties and material homogeneity, they can also introduce challenges related to die wear, surface finish, and dimensional tolerances. Balancing these factors is key to optimizing the extrusion process and achieving the desired quality of the final product.

You may be curious about how aluminum is made. From aluminum bars to the aluminum we commonly see, it has to go through a variety of processes and is made by a variety of equipment. Below we will introduce several of the most common aluminum production machinery and equipment. 1, Automatic Multi- Billet Hot Shears Furnace. The original aluminum billet is several meters long, which requires the aluminum billet to be cut and heated before the heated aluminum billett can be extruded. Automatic multi aluminum billet hot shears furnace is the newest production equipment which combine heating engineering ,mechanism ,automatic control system , hydraulic , photoelectric and thermometry in one .It is consist of aluminum bar feeding drive transport rack ,furnace ,hot shears, electricity control system and so on .     2, Aluminum extrusion machine. This is a machine that makes aluminum billet into basic aluminum Profile materials. The heated aluminum bar (the length of the aluminum bar is less than half a meter) is squeezed by strong hydraulic pressure. When the aluminum billet is squeezed by the extrusion pressure and passes through the small hole of the mold, the basic aluminum material can be formed.   3, Infrared Die Heating Furnace. Before placing the die into the aluminum extruder, the die needs to be heated. Infrared die heating furnace use iron aluminum alloy wire ,features: high efficiency and energy saving. There installed infrared radiation plate behind of the iron aluminium alloy wire which can reflect heat back to the furnace effectively , radiation plate, iron aluminum alloy wire composed of a set of infrared heater, the heating way is first radiate the heating energy in form of electromagnetic energy to the furnace hearth,then the mold absorb the electromagnetic energy and converted into heat energy.     4, Automatic Double Puller (Three Heads).This machine is used to extrusion profile traction and cutting operation. The aluminum coming out of the aluminum extruder needs to be pulled and cut to length and placed.The profile is led out of the mold cavity straightly and cooled under tension, preventing the profile from being uneven in length, hanging, or twisting, thereby improving the quality of the aluminum material.     5,Handling Table Production Line. The main function is to place and cool the aluminum. The temperature of the aluminum coming out of the extruder is relatively high and needs to be cooled naturally before the next step of processing.     6, Aluminium Profile Double Doors Ageing Furnace. Aluminum profile ageing furnace is the equipment in the process of aluminum profile heat treatment. The extruded aluminum profile needs aging heat treatment before it undering electrophoretic polishing and oxidation surface treatment technology. Aging of aluminum profile is one of the key processes of heat treatment. The heating rate and the uniformity of furnace temperature are strictly required in this process, and the aging temperature of the process is mostly (210 ±5) ℃.     In addition to the above important aluminum production equipment, there are some frequently used equipment, such as: Nitriding Furnace, Film Laminating Machine, Wrapping Machine, Hot top Casting table. 

  Extrusion oil and cutting fluids are essential components in the aluminum extrusion machine and deep processing of aluminum profiles. With the increasing demand for high-precision metal processing in the manufacturing industry, metalworking fluids are evolving towards being more environmentally friendly, of higher quality, and technologically advanced. For aluminum extrusion machines, which are large-scale equipment, the comprehensive performance requirements of hydraulic oil are very stringent. Poor-quality hydraulic oil can disrupt normal equipment operation, leading to production line stoppages and significantly impacting the economic benefits of the entire workshop.   Just as engine oil is crucial to the functioning of a car, hydraulic oil is vital to the machinery. It is imperative to further reduce the friction coefficient of hydraulic oil, which will enhance the efficiency and stability of the extrusion press.   Our aluminum extrusion machines have very stringent requirements regarding hydraulic oil and hydraulic systems. We use the most advanced hydraulic oil and systems in the industry. The pump station of the extrusion machine features an integrated design, centrally located at the rear bottom of the machine's oil tank. The system uses imported German Rexroth (Bosch Rexroth) electro-hydraulic proportional control axial piston variable pumps and a domestic stainless steel plate-type circulating filtration cooling system. The pipeline system is designed with necessary buffering and anti-vibration measures, such as buffer pads, flexible hoses, or vibration absorbers, and employs flexible rubber joints to absorb vibrations.   Isolation control valves are designed between the oil pump groups to ensure that when two mechanisms need to operate simultaneously according to the program, they do not interfere with each other. The system can achieve pump isolation, no-load start, pressure regulation, and overload protection functions. The pump head electro-hydraulic proportional valve and electronic control device are imported with the main pump and connected to the main control computer of the aluminum extruder, allowing for integrated control.   As one of the most critical components of the Aluminum extrusion machine, Huananmachine ensure the highest quality standards for our hydraulic oil system. This rigorous quality assurance is a key reason we confidently guarantee the quality to our customers.

(1) The center distance of the four stressed tie rods of the frame is symmetrical to the center of the press, so that the entire frame is stressed evenly. This can increase the squeeze Accuracy of pressed products. (2) Since the frame has a large bending resistance section, under the action of extrusion force, the frame elongation and bending deformation are small, so it is the frame can be fixed with horizontal and vertical guide rails at the bottom of the extrusion beam and extrusion barrel. The centering adjustment is very convenient, and the upper frame can be used as an X-shaped moving guide rail for the extrusion barrel.

The cylinder block and piston rod are made of 45 forged steel quenched and tempered. The two-way seal and piston rod seal of the combined piston head adopt V-ring combined seals, and are guided by copper sleeves. Hydraulic transmission and control system pump station The pump station of the Aluminum extrusion press adopts an integrated design and is centrally arranged under the rear part of the oil tank of the press. It is composed of an imported German Rexroth electro-hydraulic proportional control axial piston variable pump and a Chinese-made stainless steel plate circulation filtration and cooling system. The piping system design adopts necessary buffering and anti-shock measures, such as cushioning pads, hoses or shock-absorbing hoses, and flexible rubber pipe joints that can absorb vibration. The main system consists of 10 355L/min plunger pumps and 10 320L/min vane pumps from the German REXROTH company. They are designed to be arranged and matched in a certain combination. They can generate a pressure of 28Mpa and a flow rate of 3350L/min to meet the needs of main and side work. According to the cylinder operating speed requirements, closed-loop adjustment of the extrusion speed of 0~21mm/s is achieved, and the extrusion barrel locking cylinder is matched with a dedicated oil pump.

                                             Aluminum Extrusion press for prestressed composite frames A solid extruder structure is a prerequisite for ensuring the performance of the extruder. After being used for a period of time, many Aluminum extrusion machine become loose, the interfaces age, and the cylinders bend, resulting in deformation and unstable quality during the aluminum extrusion production process. In fact, the main reason is that the extruder as a whole is not strong enough. The stress during the operation of the extruder is very large, and our extruders mostly adopt a prestressed composite frame structure, which is composed of a high-thickness integral front beam, a high-thickness rear beam, and a square prestressed sleeve to form a closed The prestressed composite frame uses a special hydraulic preloading tool to apply an overpressure tensile load to the entire length of the tie rod, and at the same time applies compressive stress to the pressure sleeve, so that the entire frame is in a stress pretightened state, and the tension column prestress is 115% of the maximum load. above. For example, our 7500-ton hydraulic extrusion press has a front beam thickness of 1950mm made of ZG35Mn, a rear beam thickness of 1800mm (material ZG35Mn), and a square pre-applied sleeve (material ZG35). It can make it bear force better, which is also an important reason for the long service life of the extrusion machine.   Other advantages of prestressed composite frames 1. The center distance of the four stressed tie rods of the frame is symmetrical to the center of the press, so that the entire frame is stressed evenly. The main reason why the quality of aluminum materials produced is stable or unstable is whether the force is uniform. Only by maintaining uniform force can the overall density of the aluminum material be uniform, thereby improving the accuracy of extruded products.   2. The prestressed composite frame frame has a larger bending section, which makes the frame elongation and bending deformation smaller under the action of extrusion force. Therefore, the extrusion beam and the lower part of the extrusion tube can be fixed on the lower frame. The horizontal and vertical guide rails are very convenient for centering adjustment between the extrusion beam, extrusion barrel and mold. The upper frame can be used as an X-shaped moving guide rail for the extrusion barrel. On the premise of ensuring the stability of the machinery, the available space is used to reduce the space occupancy of the machinery.   3. There are two sets of elastic anchoring devices and foundation anchors on the lower part of the rear beam to make the rear beam fixed reliably.   After many years of production experience and continuous improvement based on customer feedback, our extrusion press is currently one of the most stable extruders on the Chinese market and one of the longest-lasting Aluminum extrusion machine.
