Understanding the Different Types of Standard Aluminum Extrusion Profiles

Standard aluminum extrusions play an indispensable role in many areas of modern construction, automotive manufacturing, and industrial production. Like the skeleton of a building and the support of equipment, they silently carry the core requirements of various projects, and have become a key material in promoting the efficient development of various industries. The so-called standard aluminum extrusion profiles are pre-designed, mass-produced aluminum products with a uniform and stable cross-section. As a cost-effective alternative to customized profiles, they require no additional investment in tooling development costs, and can be purchased directly from the spot, which significantly shortens the project cycle.
In this article, we will comprehensively dismantle the most common types of standard aluminum extrusion profiles, in-depth analysis of their core features, application scenarios, production processes, as well as the key points of the selection process, to help you quickly grasp the core knowledge of standard aluminum extrusion profiles, and easily select the quality products that are suitable for their own projects.

What is the Aluminum Extrusion Process?

Aluminum extrusion is a professional metal forming process, the core principle of which is to extrude the original aluminum material through external forces, processing into a precise, complex and consistent cross-section of the profile components, this process gives full play to the unique advantages of low density, high strength to weight ratio, excellent corrosion resistance, so that aluminum profiles have other metal materials difficult to compare with the value of the application.

Compared with traditional metal processing, the biggest advantage of aluminum extrusion process is that it can integrate multiple functions into a single complex component, such as structural support, thermal management and decorative surface treatment into a single unit without the need for subsequent cumbersome assembly process, which not only dramatically shortens the production time, but also effectively reduces the overall cost of manufacturing, which is especially suitable for mass production scenarios.

In addition, aluminum is infinitely recyclable, with no loss of quality in the recycling process. Perfectly suited to the concept of global sustainable development, aluminum is widely used in all kinds of green projects, and has become an important material for promoting the low-carbon transformation of industries. Whether it is structural frames in the construction field, lightweight components in the automotive field, or precision components in the aerospace field, aluminum extrusion process can meet the individual needs of different industries with its flexible molding ability, and has become an indispensable core processing technology in the modern engineering field.

What are Aluminum Extrusion Profiles?

Standard aluminum extrusion profiles are the core category of aluminum extrusion products, specifically referring to those aluminum profiles that are standardized in design, mass production, have fixed cross-sectional shapes and specifications, and can be directly supplied from stock. Their thickness, size, material and other parameters follow the industry’s common standards, and they can meet the regular needs of most industrial and commercial scenarios.

With the continuous development of engineering technology, the types and specifications of aluminum profiles continue to be enriched. From simple strips and tubes to complex shaped structures, standard profiles have always been the basic materials for various industries with their versatility and convenience. Standard aluminum extrusion profiles can’t be produced without extrusion dies, which are typically thick, round steel discs made of heat-treated H-13 steel with openings that exactly match the cross-section of the profile, capable of withstanding the immense pressures of the aluminum extrusion process of up to 100,000 to 125,000 psi, as well as high-temperature environments to ensure the precision and consistency of the profile’s formation.

Compared with custom aluminum extrusion profiles, standard aluminum extrusion profiles have significant advantages: first, the cost advantage, standard profiles do not need to invest in tooling development costs, the characteristics of mass production further reduces the unit cost, suitable for regular projects with limited budget; second, the delivery advantage, as a spot product, standard profiles do not need to wait for the tooling production and trial production cycle, can be quickly shipped, effectively shortening the project duration; and lastly, the compatibility advantage. is the compatibility advantage, standardized specifications make the same type of profiles produced by different manufacturers can be replaced with each other, which is convenient for maintenance and replacement in the later stage.

Customized profiles, on the other hand, are mainly for personalized projects with special size, shape or performance requirements. Although they can perfectly match the project requirements, they have high tooling development costs and long delivery cycles, and are more suitable for large batch sizes and scenarios with special needs.

The core reason why standard aluminum extrusion profiles are widely used in various industries lies in their combination of four characteristics: cost-effectiveness, accessibility, versatility and compatibility. Whether it’s a bracket for small household equipment or a structural frame for a large building, standard profiles can be quickly adapted to all kinds of manufacturing processes, such as cutting, drilling, welding, etc., with their standardized specifications, without the need for additional adjustments to the parameters of the equipment, which dramatically improves construction and production efficiency.

In terms of material selection, the standard aluminum extrusion profile mainly adopts three common alloys, namely 6061-T6, 6063-T6 and 1100, of which 6061-T6 alloy has high strength, good weldability and corrosion resistance, and is suitable for structural components with large loads, such as industrial brackets, mechanical frames, etc.; 6063-T6 alloy, on the other hand, has excellent extruded molding and surface finish, and is commonly used in Building decoration, door and window frames and other scenes that require high appearance and molding accuracy; 1100 alloy belongs to the pure aluminum series, with good conductivity and plasticity, suitable for electrical shells, decorative parts and other products that do not require high strength.

The Specific Flow of Aluminum Extrusion Process

Aluminum extrusion process is mainly divided into hot extrusion, warm extrusion and cold extrusion three ways, the specific choice of which process, according to the profile application scenarios, the required mechanical properties and the type of aluminum alloy used to determine.

Among them, hot extrusion is the most commonly used method in industrial production. By heating the aluminum billet to 426.7°C to 496°C (i.e., 800°F to 925°F), which exceeds the recrystallization temperature of aluminum, the aluminum material is softened so that it can be more easily shaped through the die. Profiles produced by the hot extrusion process have the advantages of high tensile strength, small dimensional tolerances, and good surface quality, which are suitable for the majority of standard aluminum extrusion It is suitable for the production of most standard aluminum extrusion profiles.

Warm extrusion is carried out at a temperature higher than room temperature but lower than the recrystallization temperature of aluminum, usually heated between 1000 °F and 1330 °F. This process can ensure the strength of the material while improving the plasticity of the aluminum material, reducing the external force required for extrusion, especially suitable for processing aluminum alloys that are easily brittle at low temperatures, and is widely used in the production of profiles for the automotive, electrical, and medical equipment industries.

Cold extrusion is carried out at room temperature or slightly below room temperature, without heating the aluminum billet, by virtue of a huge external force will be extruded billet molding, this process produces profiles with very high dimensional accuracy, good surface finish, mechanical strength is also more excellent, without the need to follow up on the surface of the treatment, suitable for the production of precision instruments, electronic devices and other parts of the high requirements for precision and strength.

No matter which extrusion method is used, the core process is inseparable from the aluminum billet preparation, heating, extrusion, cooling, finishing these key links. The raw material for aluminum extrusion is aluminum billet, also known as aluminum ingot, whose shape can be processed into square, round or customized shapes according to the production requirements. The quality of aluminum billet directly determines the performance of the final profile, so it needs to be strictly prepared before production.

In the preparation process, pure aluminum will be mixed with magnesium, silicon, copper, zinc and other alloying elements in specific proportions, and the alloy billet will be made through melting, casting and other processes, and at the same time, the billet will be removed from impurities by adopting advanced smelting and purification technologies, and then eliminated from the billet through high-pressure treatment of the internal bubbles, so as to make the material uniform in microstructure and to ensure the stability of the subsequent extrusion process and the quality of the profiles.

In the hot extrusion process, the prepared aluminum billet is first heated to a specified temperature and then conveyed to the loading device, where a layer of lubricant is applied to the surface of the billet – glass powder is usually used as the lubricant for hot extrusion, while oil or graphite is used for cold extrusion – which effectively prevents adhesion of the billet to the extruding equipment, reduces This layer of lubricant prevents the aluminum billet from sticking to the extrusion equipment, reduces friction loss, and extends the service life of the equipment and dies.

The punch assembly of the extruder then applies a large controlled pressure to push the softened aluminum billet into the die, where it passes through the die’s openings under pressure to form a profile that conforms to the shape of the die. When the profile is extruded from the mold, it is immediately cooled rapidly by liquid nitrogen spray or forced air cooling, which not only stabilizes the size of the profile and prevents deformation, but also improves the surface quality and mechanical properties of the profile while reducing the risk of damage to the mold due to high-temperature fatigue, and prolonging the service life of the mold.

The cooled profile will be guided to the discharge table by the traction device for further uniform cooling. When the profile reaches the specified length, it will be accurately cut by the cutting equipment and then transferred to the cooling table for final quenching treatment. In order to further optimize the yield strength and straightness of the profiles, the profiles will also be tensile processed, and then precisely trimmed according to the requirements to ensure that the dimensional accuracy of the profiles meets the standards.

Finally, according to different application scenarios, the profiles are subjected to subsequent treatments such as anodizing, polishing, powder coating, machining or precision assembly, so that the surface performance and appearance quality of the profiles can meet the specific standards of the industry, and the service life and aesthetics of the products can be enhanced.

As the core component of the aluminum extrusion process, the service life of the die is affected by a variety of factors such as die design, processing alloy type and extrusion temperature. During the long-term extrusion process, the die will be subject to high pressure and repeated thermal cycling, and is prone to wear, deformation and even damage. Therefore, it is necessary to prolong the service life of the die through reasonable die design, advanced thermal management technology, and surface treatment such as nitriding and coating to ensure the stability and consistency of the profile production.

Although the die needs to be replaced periodically, the high cost performance of the aluminum extrusion process can effectively offset this part of the maintenance costs, while manufacturers can also optimize the complexity of the profile, adjust the dimensional tolerances, adapt to different alloy types, etc., to further enhance the service life of the die and reduce production costs.

In addition, temperature control during the extrusion process is critical. The industry now commonly uses closed-loop feedback systems and advanced temperature sensors to monitor the temperature of the billet and die in real time, ensuring that the temperature gradient is maintained in the optimal range, thus improving the quality, uniformity, and mechanical properties of the profiles, and combining this with experienced operators and automated control platforms for efficient, high-quality mass production.

The advantages of the aluminum extrusion process are significant. In addition to cost-effectiveness, forming flexibility, and high production efficiency, the process also offers the ability for rapid prototyping, allowing for a quick response to market demands, while producing lightweight, corrosion-resistant aluminum profiles that are perfectly suited to the challenges of modern engineering.

Nowadays, transportation, building decoration, renewable energy, consumer electronics and many other industries can not do without the support of aluminum extrusion profiles, its structural integrity, aesthetics and efficient manufacturability, become an important driving force to promote the development of various industries. When selecting aluminum extrusion services, there is a need to focus on alloy selection, tooling design capabilities, secondary processing capabilities, quality assurance systems, and the supplier’s experience in their own industry so that they can obtain a tailored aluminum extrusion solution that meets both functional and regulatory requirements, as well as sustainability goals through the efficient use of recyclable materials.

Classification of Standard Aluminum Extrusion Profiles

Standard aluminum extrusion profiles are classified in various ways, among which the most central classification is based on its structural characteristics, divided into three categories: solid profiles, hollow profiles and semi-hollow profiles, each of which has its own unique structural characteristics, performance advantages and application scenarios, and the specific molding method is determined by the type of extrusion die – solid dies are used to produce solid profiles, hollow dies are used to produce hollow profiles, and semi-hollow dies are used to produce semi-hollow profiles. The specific molding method is determined by the type of extrusion die – solid die is used to produce solid profiles, hollow die is used to produce hollow profiles, and semi-hollow die is used to produce semi-hollow profiles, the design of the die directly determines the final shape and structure of the profile.

In addition, standard aluminum extrusion profiles can also be divided into angle profiles, channel profiles, tube profiles, beam profiles and other types according to the cross-section shape, different shapes of profiles to match different application requirements, which together constitute a complete system of standard aluminum extrusion profiles.

Solid Standard Aluminum Extrusion Profiles

Solid standard aluminum extrusion profiles refer to profiles without any internal voids, with simple structure and relatively easy manufacturing process, they are the lowest cost and most widely used type of standard profiles. The extrusion die for solid profiles consists of feed plate, template, pad plate and support base, in which the shape of the template directly determines the cross-section shape of the profile. Common solid standard profiles include flat bar, L-angle aluminum, T-type profile, Z-type profile, solid round bar and square bar, and so on.

The core advantage of these profiles is that they are extremely rigid and strong, with a uniform structure, easy to cut, drill, weld and other processing operations, able to withstand large loads, and low manufacturing costs, making them suitable for all types of conventional scenarios that require strength and rigidity.

The typical application scenarios of solid standard profiles are very wide, in the field of construction, commonly used in the support of building frames, wall reinforcement, door and window frames, etc.; in the industrial field, it can be used as a mechanical bracket, equipment base, transmission shafts, and other core components, used for carrying heavy loads or transferring power; in the decorative field, it can be used as decorative lines, corner protection strips, etc., with practicality and aesthetics.

It should be noted that the weight of solid profiles is relatively heavy and the material consumption is more, so in the scenes with strict requirements on weight, such as aerospace, new energy vehicles and other fields, usually give priority to hollow profiles, while solid profiles are more suitable for scenes that do not have high requirements on weight and pay attention to strength and stability.

Hollow Standard Aluminum Extrusion Profiles

Hollow standard aluminum extrusion profiles refer to profiles with completely closed internal voids. Their greatest advantage lies in the high strength-to-weight ratio, which enables them to maintain good structural strength and rigidity while reducing material consumption and lowering their own weight, making them the preferred material for lightweight design.

Extrusion dies for hollow profiles differ from solid dies in that they are equipped with an internal mandrel with two or more holes. When an aluminum billet is extruded, it separates through the holes in the mandrel and subsequently recombines inside the die to form a hollow profile with internal channels. Common hollow standard profiles include round tubes (CHS), square tubes (SHS), rectangular tubes (RHS), oval tubes (EHS), etc. The properties and application scenarios of hollow profiles vary with different cross-sectional shapes.

The structural advantages of hollow standard profiles are very prominent, in addition to the high strength-to-weight ratio, they also have good torsional and flexural resistance, which can effectively resist the distortion and deformation brought about by external forces, and at the same time, their internal hollow structure can be used for threading, conveying fluid, etc., which is both structural support and functional realization of the dual role.

In the field of construction, hollow profiles are commonly used in building frames, trusses, columns, curtain walls, etc., which can greatly reduce the dead weight of the building and ensure the stability of the structure;

In the field of transportation, it can be used as body frames and chassis components of automobiles, ships and rail transportation, etc., to realize lightweight design and improve fuel efficiency or range;

In the industrial field, it can be used as pipes for hydraulic and pneumatic systems, protective shells for equipment, etc. It can also be used as ventilation pipes for HVAC systems to play the role of heat dissipation and ventilation.

Of course, hollow standard profiles also have certain limitations, due to its internal hollow structure, when connecting the need to use a special connection to avoid the lack of strength of the connection parts, while in the humid or corrosive environment, the interior is prone to corrosion problems, the need for surface treatment and other ways to protect.

In addition, part of the hollow profile in a specific direction of the bearing capacity is relatively weak, in the selection of the need for reasonable choice according to the specific load demand. Overall, hollow standard profiles are a high-quality choice for balancing light weight, strength and economy, and are suitable for most projects with dual requirements for weight and strength.

Semi-Hollow Standard Aluminum Extrusions

Semi-hollow standard aluminum extrusion profiles are between solid profiles and hollow profiles between a class of profiles, its structure is characterized by a partially closed gap, no completely closed internal channel, die design and hollow die similar, also with mandrels and apertures, but the mandrels are not used to form a complete hollow structure of the core, so the molded profile is only part of the gap.

Common semi-hollow standard profiles include C-channel, J-channel, channel with groove, etc. These profiles combine the strength of solid profiles with the lightweight advantages of hollow profiles, and at the same time, they have good assembly flexibility, making them the most flexible type of standard profiles in terms of application scenarios.

The core advantage of semi-hollow standard profiles lies in the high degree of modularity, easy to cut, connect and fix, and can be quickly adapted to all kinds of assembly scenarios, and at the same time, its partially hollow structure can realize certain functions, such as cable storage, sliding guide and so on.

In the construction field, it is commonly used in wall installation, ceiling bracket, door and window track, etc., which can be easily fixed and assembled; in the industrial field, it can be used as cable guide groove, sliding track of equipment, heat sink, etc., which is both structural support and function realization; in the decorative field, it can be used as edge decorative strip, edge strip, etc., which can enhance the aesthetics and practicability of the product.

In addition, the smooth surface of semi-hollow profiles is easy for surface treatment such as anodic oxidation and powder coating, and the surface color and texture can be adjusted according to the needs of the application scenarios, further enhancing the appearance quality and corrosion resistance of the products.

What are the Different Types of Aluminum Extrusions?

Selection Points of Standard Aluminum Extrusion Profiles

The selection of suitable standard aluminum extrusion profiles is directly related to the quality, cost and service life of the project, so in the selection process, it is necessary to comprehensively consider a number of factors, combined with the specific needs of the project, to make a reasonable choice. The following are the core points of standard aluminum extrusion profile selection, to help you quickly select the appropriate profile products.

First of all, the load bearing requirements, different projects have different requirements for the load bearing capacity of the profile, according to the actual load of the project, the need to select the appropriate strength and rigidity of the profile. For example, for heavy machinery support, construction of the main beam and other scenes, you need to choose a larger wall thickness, high strength profiles, such as 6061-T6 alloy I beams, square tubes, etc.; used for lightweight brackets, decorative parts and other scenes, you can choose a smaller wall thickness, moderate strength of profiles, such as 6063-T6 alloy aluminum angle, decorative strips and so on. At the same time, it is also necessary to consider the torsional and flexural resistance of the profiles to ensure that the profiles can withstand the various types of external forces required by the project.

Second is the environmental conditions, environmental factors directly affect the service life of the profile, especially in the outdoor, humid, corrosive and other harsh environments, you need to focus on the corrosion resistance of the profile. For outdoor, humid environment, it is recommended to choose a better corrosion resistance alloy, such as 6061-T6, 6063-T6, while with anodizing, powder coating and other surface treatment methods to enhance the corrosion resistance of the profile; for the chemical industry, the ocean and other highly corrosive environment, you can choose 5000 series alloy profiles, which have more excellent corrosion resistance. In addition, it is also necessary to consider the temperature changes in the environment, to avoid deformation and cracking of the profile due to temperature changes.

The third is the processing and assembly needs, different projects have different processing and assembly requirements for profiles, and you need to choose profiles with good processing performance to ensure that they can be successfully cut, drilled, welded, bent and other processing operations. For example, 6063-T6 alloy profiles have better extrusion molding and weldability, which is suitable for scenes that require complex processing; 6061-T6 alloy profiles have higher strength, but are relatively more difficult to process, which is suitable for scenes with high strength requirements and little processing difficulty. At the same time, it is also necessary to consider the assembly compatibility of the profiles to ensure that the profiles can be smoothly connected with other components to reduce assembly difficulties and costs.

The fourth is cost-effectiveness. Under the premise of meeting the performance requirements of the project, cost-effective profiles should be selected to balance material costs, processing costs and maintenance costs. For example, for conventional scenes, you can choose 1000 series, 3000 series and other low-cost alloy profiles; for scenes that require strength and corrosion resistance, you can choose profiles with 6000 series alloys, which are more cost-effective, and can ensure performance while controlling costs. In addition, it is also necessary to consider the service life of the profile, choose the profile with long service life and low maintenance cost to reduce the long-term cost of the project.

Finally, standard compliance, different industries have different standard requirements, such as ISO-6362, ASTM, Aluminum Association standards, etc. In the selection process, you need to ensure that the selected profiles comply with the standards of the industry where the project is located, to ensure that the quality and performance of the profiles meet the relevant requirements. Especially in aerospace, automotive, medical and other industries with high safety requirements, it is important to strictly follow the relevant standards to avoid project pitfalls due to profiles that do not meet the standards.

Why Choose Aluminum Profiles over Other Materials?

Among many metal materials, the core reason why standard aluminum extrusion profiles can be widely used is that they have irreplaceable advantages compared with other materials such as steel and copper, and these advantages cover performance, cost, environmental protection and other aspects, which are perfectly suited to the development needs of the modern engineering field.

The first is the excellent strength-to-weight ratio, the density of aluminum material is much lower than steel, but its strength can reach or close to the level of ordinary steel, which means that the standard aluminum extrusion profiles can guarantee the structural strength at the same time, significantly reduce their own weight.

This advantage is particularly important in aerospace, automotive, rail transportation and other areas with high lightweight requirements, which can effectively improve fuel efficiency, range, while reducing transportation and construction costs. In contrast, steel is heavier and, although strong, increases project weight and cost; copper is denser and more costly, and is only suitable for specific high-precision, high-conductivity scenarios.

Second is the superior corrosion resistance, aluminum material in the air will naturally form a layer of dense oxide film, this layer of oxide film can effectively prevent further oxidation and corrosion of aluminum material, without additional coating protection, can be maintained in a regular environment in good condition. Steel, on the other hand, is prone to rust and requires additional anti-corrosion treatments such as galvanizing and painting, which increases processing and maintenance costs; copper, although it has better corrosion resistance, is more costly and dense, making it unsuitable for large-scale applications. For outdoor, humid and other corrosive environments, the corrosion resistance advantage of standard aluminum extrusion profiles is more prominent, can significantly extend the service life and reduce maintenance costs.

The third is good environmental protection and sustainability, aluminum materials are 100% recyclable, and the recycling process will not lose its own quality, the energy required to recycle aluminum is only 5% of the energy required to produce virgin aluminum, which can significantly reduce energy consumption and carbon emissions, which is in line with the global low-carbon and environmental protection development concept. The recycling rate of steel, copper and other materials is lower, and the recycling process will produce more pollutants, less environmentally friendly. With the global emphasis on sustainable development, standard aluminum extrusion profiles, as environmentally friendly materials, are increasingly favored by various industries.

The fourth is extremely high versatility and flexibility. Standard aluminum extrusion profiles are available in various specifications and shapes, which can be adapted to the needs of different industries and scenarios, and at the same time, they have good processing performance, can be cut, drilled, welded, bent, and other processing operations, and can be flexibly adjusted in shape and size according to the project needs, without the need for complex processing equipment and processes. In contrast, steel is more difficult to process and requires specialized cutting and welding equipment; copper is more expensive to process and has a relatively single shape and specification with poor adaptability.

Finally, it is good cost-effectiveness. Although the initial cost of standard aluminum extrusion profiles may be higher than that of ordinary steel, their overall cost is rather lower in the long run due to their long service life, low maintenance costs, and lower transportation and construction costs brought about by lightweighting. For example, in construction projects, the use of aluminum profiles instead of steel can reduce the human and material costs of transportation and construction, while eliminating the need for frequent maintenance, significantly reducing the long-term cost of the project; in the automotive field, lightweight aluminum profiles can improve fuel efficiency, reduce operating costs, and bring significant economic benefits.

What Quality Control Measures Ensure Profile Integrity?

The quality of standard aluminum extrusion profiles is directly related to the safety and stability of the project, so in the production process, it is necessary to establish a perfect quality control system, from raw materials to finished products leaving the factory, to carry out the whole process of quality supervision, to ensure that the quality of the profiles meets the standard requirements. Quality control is a systematic process, not a single inspection link, but throughout each step of production, mainly including raw material inspection, production process monitoring, dimensional accuracy inspection, finished product inspection and final audit and other links.

Raw material inspection is the basis of quality control. The quality of aluminum billet directly determines the performance of the final profile. First of all, it is necessary to confirm the alloy composition of aluminum billet to ensure that it meets the project requirements, such as 6061-T6, 6063-T6, etc. It can be verified through the material proof provided by the supplier, combined with spectral analysis, etc. Avoid using billets with inconsistent alloy composition, because the wrong alloy composition will directly affect the strength, corrosion resistance and processing performance of the profiles.

At the same time, it is also necessary to check the appearance and internal quality of aluminum billets, remove billets with cracks, bubbles, impurities and other defects, and ensure that the billets have uniform density and are free of defects.

Production process monitoring is the core link of quality control, mainly for real-time monitoring of key parameters in the extrusion process to ensure the stability of the production process.

The first is the monitoring of the die state, you need to regularly check the wear and tear of the die, dimensional accuracy, timely maintenance and replacement, to avoid problems such as profile size deviation and surface defects caused by die wear;

Second is the temperature control, through the temperature sensor real-time monitoring of the temperature of aluminum billet and die, to ensure that the temperature is maintained in the optimal range, to avoid too high or too low a temperature resulting in poor profile molding, mechanical properties degradation and other issues;

Lastly, the extrusion speed is monitored to maintain a stable extrusion speed to ensure that the cross-section of the profile is uniform and the dimensions are consistent, to avoid uneven wall thickness, surface scratches and other defects due to speed fluctuations in the profile.

Dimensional accuracy check is the key to ensure that the profile meets the standard, and it is necessary to carry out several dimensional checks during and after the extrusion process.

During the extrusion process, operators use tools such as calipers, micrometers, profile projectors, etc., to sample and check the key dimensions of the profiles, so as to discover the dimensional deviations and adjust the production parameters in a timely manner;

After the extrusion is completed and the profile is cooled, high-precision equipment such as coordinate measuring machines (CMM) will be used to inspect the full dimensions of the profile to ensure that the dimensional tolerances of the profile comply with industry standards and project requirements. For critical dimensions and assembly dimensions, the tolerance range needs to be strictly controlled to avoid the subsequent assembly and use being affected by dimensional deviations.

Finished product inspection includes two parts: appearance inspection and mechanical performance inspection. Appearance inspection mainly checks the surface quality of the profile, removes the products with scratches, pits, oxidized spots, mold marks and other defects, and ensures that the surface of the profile is smooth and free of defects; Mechanical performance inspection examines the strength, hardness, elongation and other mechanical properties of the profile by means of hardness test (e.g. Rockwell hardness test, Brinell hardness test) and tensile test to ensure that it meets the project requirements. Mechanical performance inspection is to check the strength, hardness, elongation and other mechanical properties of the profiles by means of hardness test (such as Rockwell test, tensile test, etc.) to ensure that they meet the project requirements. For mass-produced profiles, sampling inspection will be used to ensure the consistency of product quality; for profiles with high precision requirements, full inspection will be carried out to avoid unqualified products leaving the factory.

Final audit and documentation is the last link of quality control, before the profiles are shipped out of the factory, it is necessary to carry out a final quality audit to confirm that all the inspection links have been completed and the inspection results meet the requirements, and at the same time, check whether the packaging of the profiles meets the requirements, to avoid damage in the transportation process.

In addition, it is also necessary to establish a perfect documentation system to record the material certification of raw materials, parameters in the production process, inspection results and other information to achieve product traceability, to ensure that once the quality problems occur, the cause can be traced back in a timely manner and rectification. Selecting a supplier with a perfect quality control system is the key to ensure the quality of standard aluminum extrusion profiles, which can provide a strong guarantee for the smooth progress of the project.
