As a large aluminum extrusion machine, it is equipped with various components and possesses multiple functions, making its structure relatively complex. The extrusion machine is composed of the frame, electric and hydraulic systems, conveying system, heating system, die system, control system, shearing system, etc. Among these, the frame, electric and hydraulic systems, die system, and control system are the most critical. 1、FrameThe frame is one of the most important parts of the extrusion machine: it bears the weight and impact pressure of the entire machine. It needs to be made of high-strength steel. A structurally stable frame can withstand high extrusion forces, and its load-bearing capacity is especially important for manufacturing high-strength, high-precision aluminum profiles. It ensures that the aluminum extrusion machine can stably, accurately, and continuously produce aluminum profiles, which is also a key factor affecting the service life of the machine.The frame structure of the aluminum extrusion machine produced by our company, Huanan Heavy Industry(www.huananmachine.com), is composed of an integrally forged front crossbeam, a cast rear crossbeam, tie rods with a diameter of φ350 (material: 42CrMo), and square pressure sleeves, forming a closed prestressed composite frame. Special hydraulic preloading tools are used to apply super-pressure tensile loads along the entire length of the tie rods and compressive stress to the pressure sleeves, putting the entire frame in a prestressed state. The center distances of the four load-bearing tie rods are symmetrical with respect to the center of the press, ensuring uniform force distribution across the entire frame. This improves the precision of the extruded products. Two sets of elastic anchoring devices are installed at the bottom of the rear beam and anchored to the foundation, ensuring reliable fixation of the rear beam. The stable and sturdy frame structure is also one of the reasons why our extrusion machines have a longer service life compared to those of our peers.   2、Electric Motor and Hydraulic SystemThe extrusion machine has two power sources: electricity and hydraulics. As the driving source of the aluminum extrusion machine, the electric motor and hydraulic system require precise control and monitoring to ensure optimal performance. Key components include: Main Cylinder Extrusion Stem Extrusion Container Main Cylinder: Provides enormous extrusion force (ranging from hundreds of tons to tens of thousands of tons) to drive the extrusion stem forward. Requires high stability, sealing performance, and fatigue resistance. Extrusion Stem (Extrusion Shaft): Transfers the pressure from the main cylinder to the aluminum billet, pushing it through the die for shaping. It must be heat-resistant and wear-resistant, typically made from high-strength alloy steel (e.g., H13). Extrusion Container (Billet Container): Holds the heated aluminum billet and withstands the high pressure and temperature during extrusion. The inner lining must be resistant to high temperatures (400–500°C) and wear. It typically has a layered design, with a prestressed outer sleeve and a replaceable inner lining.   3、Die SystemDifferent aluminum profiles require different dies. The shape and dimensions of the die directly determine the cross-sectional shape and dimensional accuracy of the extruded aluminum. Therefore, die fabrication requires precision and stability. Dies are generally made of high-strength steel (such as H13 steel) to withstand the tremendous extrusion force.   4、Control SystemThe operation of the extrusion machine requires a complex control and monitoring mechanism. The electrical control system of our aluminum extrusion machines at Huanan Heavy Industry adopts a two-level control system based on industrial programmable logic controllers (PLCs). Sensors are arranged throughout various parts of the extrusion machine to monitor pressure, temperature, displacement, and other parameters in real time. The PLC system enables full process control of the machine.The control panel is equipped with operation buttons, while the touch screen includes touch switches, digital displays of extrusion speed, stroke, extrusion force, extrusion container temperature, and indicators for machine status and fault alerts.

At present, aluminum profiles come in a variety of shapes, including solid, semi-hollow, and hollow shapes. These profiles play a crucial role in shaping and enhancing the functionality of many everyday products, from household appliances to automobiles. Aluminum profiles are favored by customers for their excellent strength, stability, corrosion resistance, and lightweight characteristics.   The basic steps from aluminum billet to aluminum profile are as follows: 1、Heating the aluminum billet, 2、Extruding the aluminum billet, 3、After the billet is extruded through the mold, pulling the aluminum profile with a traction machine, 4、Cooling the aluminum profile, 5、Surface treatment of the aluminum profile. These steps may look simple, but they require some machinery to perform. Among them, the design and manufacture of the mold are very important parts. The mold is created to match the shape and dimensions required for the final product. Aluminum extrusion molds are usually made of steel or tungsten steel alloy and can withstand thousands of extrusions. 1、The aluminum billet is heated using a MULTIPLE ROD HOT SHEAR FURNACE. The aluminum billet or raw material is usually a long cast rod. It is cut to the appropriate length and heated to a temperature that gives it sufficient ductility for extrusion.   2、The heated aluminum billet is then placed into the Aluminum extruder for extrusion. After passing through the extrusion mold, the aluminum is formed into the desired shape. Currently, there are two modes of extrusion for aluminum billets: one is direct extrusion, and the other is indirect extrusion.In direct extrusion (also known as forward extrusion), the billet is placed in a container, and a ram is used to push the billet through the mold opening. The force applied by the ram causes the aluminum to flow through the mold opening, forming the shape of the mold. The extruded part is pushed out of the mold at the end of the process. Direct extrusion is typically used to produce solid shapes such as rods, bars, and tubes.Indirect extrusion is also called reverse extrusion or backward extrusion. In the indirect extrusion process, unlike the direct extrusion process where the billet is pushed through the mold, in indirect extrusion, the mold is pushed toward the billet to form the desired extruded shape. The mold is placed at the end of the ram (a hollow mandrel), the billet is loaded into the container, and then the ram is forced toward the billet, causing the billet to pass through the mold and produce the aluminum extrusion. The main advantage is that there is no friction on the surface of the billet. This reduces the extrusion load, allowing the same aluminum extrusion to be produced with a smaller machine, or a larger extrusion to be produced with the same machine. There is also no heat generated by billet-container friction. This results in better extrusion flow, fewer variables, a more consistent and easier process, and the final extruded material has better tolerances and more stable shapes.Both direct and indirect extrusion processes have their own advantages and disadvantages. The direct extrusion process is a simpler process and is usually faster, making it more cost-effective to produce simple shapes. On the other hand, the indirect extrusion process allows for the creation of more complex shapes, and due to the uniformity of material flow, parts with higher structural integrity can be produced.   3、Full servo double puller is used to pull the aluminum material, keeping the aluminum straight. The traction machines currently in use generally have a shearing function to cut the aluminum material to a suitable length, which is then cooled with water or allowed to cool naturally on a cooling table. The extruded aluminum is cooled by air or water, which helps it retain its shape.   4、The extruded aluminum is usually cut to the required length and then subjected to any necessary finishing processes, such as painting, anodizing, powder coating, or polishing. This step usually requires the use of an Ageing Furnace.   If you want to know more about aluminum extrusion machine, please visit our website www:huananmachine.com.

Recently, a client from the Middle East visited our factory and intended to purchase an aluminum extrusion press for manufacturing door and window materials. We recommended the customer to purchase a 5-inch extrusion press, specifically our 1100T aluminum extrusion press. Through our discussion, we realized that the customer had limited knowledge about extrusion presses. Previously, he used to purchase aluminum materials for making doors and windows, but now he plans to buy an extrusion press to produce aluminum materials himself. Someone had suggested that he should buy an 1800T aluminum extrusion press for producing door and window aluminum materials. However, based on the sizes of the door and window materials he needs, we recommended the 1100T aluminum extrusion press instead.   Our Huanan 1100T aluminum extrusion press is also a 5-inch aluminum extrusion press, which is suitable for extruding various door and window aluminum profiles. The extrusion cylinder specifications of our 1100T aluminum extrusion press machine are: Diameter: 132mm Length: 800mm Applicable aluminum billet size: Diameter: 127mm Length range: 400–750mm     Considerations When Extruding Aluminum: Extrusion Pressure       When extruding aluminum, it is crucial to consider the extrusion pressure. If the extrusion press tonnage is too high relative to the aluminum billet diameter and alloy type, the following issues may occur: 1. Over-Extrusion Excessive Metal Flow Rate: Too much pressure can cause excessively fast metal flow, affecting dimensional accuracy and surface quality. Overheating: Excessive extrusion pressure can lead to rapid temperature rise, potentially causing surface roughness, cracks, or even burning.   2. Mold and Die Damage Shortened Die Lifespan: Excessive pressure may exceed the die’s load capacity, leading to rapid wear or even breakage. Die Deformation: Continuous use of an overpowered press can cause plastic deformation of the die, affecting profile accuracy.   3. Equipment Damage Accelerated Extrusion Cylinder Wear: Higher pressure accelerates wear on the inner wall of the extrusion cylinder, shortening its lifespan. Hydraulic System Overload: If the tonnage is too high, the hydraulic system may overheat, experience pressure failures, or even develop leaks.   4. Negative Impact on Product Quality Coarse Grain Structure: Excessive extrusion speed can lead to larger metal grains, reducing mechanical performance. Increased Defects: High stress and temperature may introduce bubbles or inclusions inside the aluminum, affecting product quality. Reduced Dimensional Accuracy: Overpowering the extrusion process may lead to unstable profile dimensions and out-of-tolerance products.   5. Increased Production Costs Higher Energy Consumption: A high-tonnage extrusion press consumes more energy, leading to unnecessary waste if the press is oversized. Increased Maintenance Costs: Faster wear and tear on molds, extrusion cylinders, and hydraulic systems lead to higher maintenance and replacement costs.     Choosing the Right Extrusion Press     When purchasing an aluminum extruder, it is essential to determine the size of the aluminum profiles to be produced and ensure that the press tonnage is appropriate.

This helped the customer better understand the Aluminum extrusion process and the necessary machinery, giving him a clearer view of the entire aluminum manufacturing process.  

                                  The similarities and differences between copper extrusion and aluminum extrusion Aluminum is one of the most common materials in our daily lives and an essential metal in various industries. However, in addition to aluminum, copper is also a widely used metal due to its excellent electrical and thermal conductivity, corrosion resistance, and other favorable properties. Copper has broad applications across multiple industries, such as:   Electrical and Electronics: Wires, cables, transformers, motors, and electronic components. Construction: Piping systems, electrical wiring, and copper conductors. Automotive: Electrical systems, radiators. Industrial Equipment: Heat exchangers, valves, pumps, bearings, and gears. Telecommunications: Cables. Energy: Solar panels, generators. Healthcare: Medical devices, surgical instruments, door handles, and handrails due to its antibacterial properties. Both aluminum and copper are produced through extrusion processes, where pressure is applied to metal billets, forcing them through molds to form the desired shapes. While the basic production process is similar for both materials, copper and aluminum differ significantly in their properties, which affects their production methods and equipment.   Production Process: Both aluminum and copper extrusion processes involve applying hydraulic or mechanical pressure to metal billets, which are heated to increase their plasticity for easier extrusion. The extrusion equipment, including extrusion cylinders, molds, extrusion rods, and heating systems, are similar for both metals. However, because copper and aluminum have different properties, the specific production conditions, such as temperature and pressure, vary.   Differences Between Aluminum and Copper:   Aluminum: Density: Low Melting Point: Approximately 660°C Plasticity: High, making it easier to extrude Extrusion Pressure: Relatively low   Copper: Density: High Melting Point: Approximately 1085°C Hardness: Higher, making extrusion more difficult Extrusion Pressure: Higher due to its hardness Because of these differences, the heating temperature required for aluminum and copper extrusion is not the same. For aluminum, the heating temperature typically ranges from 400°C to 500°C, while for copper, it is generally higher due to its higher melting point. This difference in properties also results in copper requiring higher extrusion pressures compared to aluminum. This is one of the reasons why our HuaNan heavy Industry can produce copper extruders in addition to aluminum extruders.   Molds: Mold material plays a crucial role in determining the extrusion quality. Aluminum extrusion molds are usually made from high-strength steel, offering durability. Copper extrusion molds, on the other hand, require materials with higher wear and heat resistance, making them less durable than aluminum molds.   Lubrication: The choice of lubricant also differs. Aluminum extrusion typically uses graphite or oil-based lubricants, while copper extrusion requires high-temperature lubricants such as glass lubricants to manage the higher extrusion pressures.   Cooling: After extrusion, cooling methods vary. Aluminum cools faster and is typically cooled using air or water, while copper requires a slower, gentler cooling process to prevent cracking.   Post-Treatment: Aluminum often undergoes anodizing or spraying treatments, while copper is usually treated through electroplating or polishing to achieve a smooth finish.   Production Costs: Despite similar production processes, the costs of extruding copper are generally higher than for aluminum due to copper's higher extrusion pressures and material costs.   Summary: In conclusion, while the extrusion processes for aluminum and copper are fundamentally similar, the differences in their material properties lead to distinct requirements for heating, extrusion pressure, mold materials, lubrication, cooling, post-treatment, and cost. Copper extrusion typically involves higher pressures, more specialized molds, and more complex handling, which results in higher production costs compared to aluminum extrusion.

                                                             Forging and casting are two common metalworking processes, each with its own advantages and disadvantages, suitable for different applications.   Let’s start by looking at the benefits of forging over casting:   Higher Strength: During the forging process, the grain structure of the steel is compressed and refined, enhancing its strength and toughness.   Better Fatigue Performance: Forged parts can withstand repeated stresses, making them ideal for high-load and dynamic stress applications.   Fewer Internal Defects: Forging reduces defects such as porosity and shrinkage, improving the material’s density and overall quality.   High Dimensional Precision: Forged parts have precise dimensions, requiring minimal post-processing, which saves both material and time.   At Huannan Heavy Industry, we use forging for the main components of our aluminum extrusion machines, including the front beams, tension columns, extrusion rods, and extruder container. This allows our machines to better withstand the impact forces during extrusion.   In contrast, many competitors use cast steel for components like the front beam and tension column. The drawback of casting is that the material’s strength is lower due to a coarser grain structure, and casting is more prone to internal defects like porosity and shrinkage. These defects can weaken the material and affect its overall performance.   Aluminum extrusion machines made with cast steel are more likely to suffer from insufficient toughness and strength, making them prone to damage under prolonged operational pressure. While casting is more cost-effective, the quality simply cannot match that of forged steel. This is why our extrusion machines may be priced higher than those of our competitors, but the superior quality and longer service life make them a much better investment in the long run.   This is the confidence we have in Huannan Heavy Industry’s aluminum extrusion machines—our commitment to quality sets us apart.

An aluminum extrusion machine is a commonly used industrial device for shaping aluminum alloys into various profiles through the extrusion process. Understanding its working principle and structure is crucial for optimizing extrusion and profile production. Working Principle of the Aluminum Extrusion Machine The aluminum extrusion machine typically consists of several key components 1 Heating SystemThe heating system heats the aluminum alloy to the appropriate extrusion temperature before it is fed into the extrusion chamber. This system commonly uses electric or gas heating to achieve the desired temperature for efficient processing.  2 Extrusion ChamberThe extrusion chamber contains a mold cavity, or die, with the desired cross-sectional shape of the aluminum profile. Inside the chamber, aluminum alloy is fed and pressed through the die, forming the required profile. 3 Feeding and Pressing SystemAluminum alloy is introduced into the extrusion chamber through a feeding system. A piston or screw mechanism applies pressure to force the aluminum through the die, shaping it into the desired profile. 4 Cooling SystemA cooling system rapidly cools the extruded aluminum profile to maintain its shape and ensure its performance. This step prepares the profile for subsequent processing and treatment.   Key Considerations in the Extrusion Process 1 Temperature ControlMaintaining the correct heating temperature is essential for ensuring the aluminum alloy has the right plasticity, making it easier to extrude. 2 Chamber and Die DesignThe design of the extrusion chamber and die plays a critical role in achieving the desired profile shape. Proper design ensures uniform filling of the aluminum alloy in the die and maintains the stability of the profile's geometry during the process. 3 Cooling EfficiencyThe cooling system significantly affects the quality and properties of the extruded profile. Proper cooling speed prevents deformation, cracks, or other defects, ensuring the final product's durability and performance. In summary, understanding the aluminum extruder structure and working principle allows manufacturers to optimize the extrusion process and produce high-quality aluminum profiles efficiently.

With the increasing adoption of aluminum profiles across various industries, the complexity of profile cross-sections and dimensions continues to grow. Aluminum extrusion press machine, as key equipment in aluminum product manufacturing, significantly impact the surface quality and dimensional precision of aluminum profiles. A high-quality extrusion press can bring substantial economic benefits to enterprises. As the industry trends toward larger-scale and automated presses, selecting the right equipment has become a crucial challenge for manufacturers. Below are some practical guidelines to assist in choosing the most suitable Extrusion press, using Huanan Heavy Industry Technology Co., Ltd. as an example. 1. Choose Based on Machine Type Extrusion presses can be categorized by their structure, transmission method, and functional purpose. Common types include hydraulic, oil-hydraulic, vertical, horizontal, forward extrusion, and backward extrusion presses. When selecting the appropriate type, consider the specific aluminum alloy and its intended application. For instance, a forward single-action horizontal press is ideal for extruding 6063-T5 industrial aluminum profiles, while a forward double-action horizontal press suits soft alloy tubing. Enterprises should choose based on their production needs and budget. In industrial production, forward single-action horizontal hydraulic extrusion press machine are the most widely used. 2. Choose Based on Extrusion Capacity After deciding on the type, the next step is to determine the press's extrusion capacity. Extrusion presses are classified as heavy-duty, large, medium, or small based on their force capacity. For example, a 7500-ton hydraulic press is heavy-duty, a 4000-ton press is large, a 2500-ton press is medium, and presses under 1000 tons are small. The required extrusion capacity is calculated based on production conditions, technical capabilities, and market demands. Parameters such as annual production hours and hourly output must be considered.The size and complexity of the profile cross-section, as well as the alloy composition, dictate the required extrusion force. For example, standard aluminum profiles typically require 250-400 MPa, hollow profiles need 450-1000 MPa, while pure aluminum requires a lower force of 150-250 MPa. Additionally, the extrusion method impacts the force required—forward extrusion generally demands 1/3 more force than backward extrusion. 3. Choose Based on Equipment Grade Once the type and capacity are decided, the next step is to select the appropriate grade of extrusion press. This choice should align with the manufacturer’s product positioning and budget. For mid-range aluminum profiles, domestic extrusion presses are a cost-effective option. However, for high-end products, investing in imported equipment may be necessary.Regardless of the grade, the decision should be practical and economically sound. For instance, if your production focuses on mid-range profiles, there’s no need to opt for high-cost imported presses from Germany. Not only is the initial investment significantly higher, but maintenance and operational costs also increase, potentially impacting production schedules. It’s essential to evaluate all aspects comprehensively and choose Aluminum extrusion equipment that fits your operational needs and financial capacity. By following these principles, aluminum profile manufacturers can make informed decisions, ensuring efficiency and quality while optimizing costs.

                                 What materials can be extruded using an aluminum extrusion machine? Extrusion casting, also known as liquid die forging, involves completing the filling, solidification, and shrinkage compensation processes under pressure, which refines the grain size, improves the microstructure, and controls casting defects. The most significant feature of extrusion casting compared to other solid-liquid forming methods is high-pressure solidification and crystallization. The process is highly adaptable and suitable for producing multi-alloy systems, including both cast and forged aluminum alloys. It is also effective for creating complex-shaped, thick-walled, and large-cast parts. The process is simple and can be easily automated. Extrusion castings have excellent microstructural quality, with fine grains, compact microstructures, low porosity, and superior mechanical properties. The castings can undergo solid solution and aging treatments, offering high surface quality and dimensional accuracy. Due to these advantages, extrusion casting has largely replaced other forming methods in the production of precision, high-quality castings and parts that meet special performance requirements, such as high strength, toughness, wear resistance, and gas-tightness, in industries like automotive, telecommunications, high-speed rail, and power generation. Alloy materials play a crucial role in determining process parameters and directly influencing the service life of molds. Currently, aluminum alloys and aluminum-based composites are the focus of extrusion casting materials. Among them, Al-Si, Al-Cu, and Al-Zn series aluminum alloys are the most widely used, with the research on Al-Si alloys being the most developed due to their excellent casting properties. Key factors such as filling ability, hot crack sensitivity, and shrinkage compensation ability are critical indicators of alloy performance in casting processes. It has been found that extrusion casting exhibits strong adaptability to aluminum alloys, with relatively low requirements for the alloy’s processability—emphasizing instead the alloy’s end-use performance. To meet specific performance requirements like high strength, toughness, wear resistance, corrosion resistance, fatigue resistance, and creep resistance, the development of dedicated extrusion casting alloys is essential. Expanding the application range of aluminum alloy extrusion casting technology and improving casting quality remain enduring themes in the development of this field. Huanan Heavy Industry Technology Co., Ltd, Our company has made significant progress in Aluminum extrusion machine, tooling, process control, and numerical simulation technologies. The direction of extrusion casting products is moving towards larger, more complex designs, with greater emphasis on controlling temperature and stress fields to reduce casting defects. We have made breakthroughs in both equipment and process areas to support this development.

The process characteristics and advantages of aluminum extrusion molding In recent years, driven by the demand for miniaturization and lightweight design across various industries, aluminum and its alloys have gained significant popularity due to their excellent malleability, high strength, corrosion resistance, and light weight. As a result, aluminum extrusion products have seen increasing use in fields such as construction, packaging, transportation, electronics, healthcare, and aerospace.   Definition of Aluminum Extrusion Aluminum extrusion is a forming process where an aluminum alloy billet is placed in a die cavity (or extrusion chamber) and subjected to substantial pressure. This pressure causes the aluminum to undergo directional plastic deformation and flow through the die openings, creating profiles with desired cross-sectional shapes, dimensions, and specific mechanical properties.   Types of Aluminum Extrusion Processes Aluminum extrusion can be classified into several types based on the metal flow direction relative to the die's motion:   Direct Extrusion: The metal flows in the same direction as the die's movement. Indirect Extrusion: The metal flows in the opposite direction to the die's movement. Compound Extrusion: Part of the metal flows in the same direction as the die movement, while the other part flows in the opposite direction. Radial Extrusion: The metal flows at a 90-degree angle to the die's movement. Key Features of the Aluminum Extrusion Process The extrusion process places the metal under intense three-dimensional compressive stress, providing it with better plasticity compared to rolling or forging. Extrusion allows the production of not only simple shapes (like rods and tubes) but also complex profiles. It offers high flexibility, as changing a die can enable the production of different shapes, sizes, and types on the same equipment—resulting in a time-efficient and highly adaptable process. Extruded products exhibit high dimensional precision, excellent surface quality, and improved material utilization. The process enhances the mechanical properties of the metal. With a relatively short process flow, extrusion allows the production of large, integrated components in a single step. It requires lower investment in equipment and dies, making it cost-effective. Aluminum alloys are particularly suited for extrusion, supporting diverse extrusion processes and die structures. Advantages of Aluminum Extrusion Enhanced Deformation Capability: Aluminum in the extrusion zone undergoes strong triaxial compressive stress, optimizing its plasticity and allowing significant deformation. High Product Quality: Extrusion improves the structure and mechanical properties of aluminum. After quenching and aging, extruded products achieve superior longitudinal strength (along the extrusion direction) compared to other processing methods. Extruded products also feature high dimensional accuracy and excellent surface finish. Wide Product Range: Extrusion can produce simple profiles like tubes, bars, and wires, as well as intricate hollow and solid shapes. It also enables variable cross-sectional profiles that are difficult or impossible to create through other plastic forming methods. Production Flexibility: Extrusion is highly adaptable, allowing for the production of different products on the same equipment simply by changing the die. This ease of tool change makes it a quick and efficient process.   Simple Process and Low Investment: Compared to other methods like piercing rolling or groove rolling, extrusion has a simpler production process, requires fewer pieces of equipment, and demands lower investment.

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. With continuous technological innovation in our aluminum extrusion machinery, our equipment has reached a high level of maturity in extruding photovoltaic aluminum profiles.

                                          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.
