Industrial aluminum profiles are industrial aluminum profiles that are produced by hot melting aluminum rods to obtain different shapes, sizes, and properties. The production process is as follows:

Aluminum rod preparation: Firstly, suitable pure aluminum rods or aluminum alloy rods need to be prepared. The quality and composition of these aluminum rods have a decisive impact on the performance of the final extruded industrial aluminum profiles.

Hot melt: The aluminum rod is fed into the furnace for heating, reaching a temperature suitable for extrusion. This process is called hot melting.

Extrusion: The hot melted aluminum rod is fed into the extruder and formed into the desired cross-sectional shape through the extrusion effect of the mold. The design and manufacturing of molds play a decisive role in the cross-sectional shape, dimensional accuracy, and surface quality of aluminum profiles.

Cooling and straightening: The extruded aluminum profile needs to undergo a cooling process to stabilize its shape and size. Subsequently, straightening may be necessary to ensure the straightness and flatness of the aluminum profile.

Surface treatment: As needed, aluminum profiles can be surface treated, such as anodizing, sandblasting, powder spraying, etc., to increase their corrosion resistance, aesthetics, or other functionality.

Quality inspection: Finally, conduct quality inspection on the aluminum profile to ensure that it meets relevant standards and specifications. This may include size measurement, mechanical performance testing, visual inspection, etc.

Industrial aluminum profiles have been widely used in various industries due to their lightweight, high strength, corrosion resistance, ease of processing, and modular connections, such as mechanical manufacturing, automation equipment, transportation, chemical, food, medical, and more.

The processing method of industrial aluminum profiles mainly includes the following four steps:

Cutting: As industrial aluminum profiles are generally 6 meters long, they need to be cut into appropriate lengths according to actual needs. Cutting includes length cutting and angle cutting. Common angle cutting includes 45 degree angle cutting and special angle cutting. In order to ensure high surface smoothness, no burrs, and no need for secondary processing of aluminum profiles, professional aluminum profile cutting saws are usually used in conjunction with professional circular saw blades for processing.

Drilling: Drill holes on the surface of aluminum profiles as needed to install industrial holes. The position of the hole needs to be drilled at the designated position according to the different dimensions of industrial aluminum profiles and drawing requirements. Industrial holes generally have through holes, countersunk holes, blind holes, installation holes, etc., and strict control of the position accuracy and depth of the holes is required.

Tapping: Drill and tap holes in the center of the aluminum profile end face that needs to be connected for bolt installation. The tapping process needs to be carried out according to the size of the installation bolts.

Precision machining: Precision machining generally includes precision machining services such as hole milling, slot milling, surface milling, end milling, etc., to meet specific design or functional requirements. These processing steps can usually be completed in conjunction with CNC and other processing equipment.

The processing method of industrial aluminum profiles has some significant advantages and relatively few disadvantages.


Lightweight and High Strength: Aluminum has a low density, so the processed aluminum profile is lightweight, but its strength and stiffness are high, making it suitable for applications that require weight reduction.

Easy to process: Aluminum profiles have good plasticity and machinability, and can be customized through various processing methods such as cutting, drilling, and tapping, making it easy to achieve various complex design requirements.

Corrosion resistance: The aluminum surface will form a strong oxide film, which has good corrosion resistance and can be used for a long time in harsh environments such as humidity, acid and alkali.

Modular connection: Aluminum profiles can be quickly connected using various modular aluminum accessories without welding, making disassembly and assembly convenient. They can quickly construct various mechanical structures, frames, etc.

Aesthetics: After treatment, the surface of aluminum profiles has a beautiful appearance and uniform color, which can improve the overall appearance quality of the product.


High cost: The manufacturing cost of aluminum profiles is relatively high, especially when complex processing and surface treatment are required, the cost will further increase.

Relatively insufficient rigidity: Although aluminum profiles have high strength, their rigidity may be slightly insufficient compared to some other metal materials, so they may not be suitable in certain application scenarios that require extremely high rigidity.

Easy to deform: Aluminum profiles are prone to deformation or warping if not handled properly during processing and use. Special attention should be paid to the accuracy of processing and installation.

Limited temperature resistance: Aluminum has relatively limited temperature resistance, and its performance may change in high or low temperature environments. It is necessary to pay attention to the limitations of the usage environment.
