What Are Processing Of Aluminum Profiles - 6 Methods

Updated: 28 May 2024
We know that aluminum profiles are generally extruded through dies. There are two main methods of extrusion processing of aluminum profiles: cold and hot. Our common aluminum profile products are generally hot extrusion. Compared with cold extrusion, the hot extrusion process is relatively simple, while the cold extrusion process is more complex. Usually only products in special fields require the cold extrusion process. After the aluminum profile is extruded from the die, it must undergo various processing before it can be used. So what are the usual processing methods for aluminum profiles? Shenghai Aluminum summarizes 6 commonly used aluminum alloy processing methods.

1. Surface treatment (coloring)
The surface treatment of aluminum profiles improves its corrosion resistance, aesthetics and service life. Common surface treatment methods include anodizing, powder coating, electrophoresis, etc. Anodizing improves corrosion resistance and hardness by forming a dense oxide film on the surface of aluminum. Powder coating is to spray paint on the surface of aluminum to form a protective film, which is beautiful and durable. Electrophoresis uses electrolysis to form a uniform coating on the aluminum surface, which has good adhesion and corrosion resistance.
And through surface treatment, the color of the surface of the aluminum profile is also enriched. Common surface colors of aluminum profiles include: anodized silver, black, white, gold, champagne, brushed black, bronze, etc. These colors are often very popular with clients in the construction industry (windows, doors, baseboards, tile trim, LED profiles).

2. Cutting processing
Cutting is one of the most basic operations in aluminum profile processing. Common cutting methods include mechanical, laser, water, etc. Mechanical cutting is suitable for thicker aluminum profiles and is performed by equipment such as saws or cutting machines. Laser cutting is suitable for thin aluminum materials and has the characteristics of high precision and high efficiency. Water cutting uses high-pressure water flow to cut aluminum materials. The cutting surface is smooth and has no thermal influence, and does not cause heat to the profile.

3. Bending processing
The bending process of aluminum profiles uses a certain external force to plastically deform the aluminum profiles to achieve the required shape and angle. Common bending methods include cold bending and hot bending. Cold bending is the bending of aluminum materials at room temperature and is suitable for thinner aluminum materials. Hot bending is to heat the aluminum to a certain temperature and then bend it, which is suitable for thicker aluminum. The bent aluminum profiles have a beautiful and elegant appearance and are often used in building doors, windows, decoration and other fields.

4. Drilling processing
Drilling is one of the common operations in aluminum profile processing, mainly used to make connecting holes, mounting holes, etc. Common drilling methods include drilling with a drilling machine, drilling with a milling machine, etc. During the drilling process, it is necessary to pay attention to the accuracy of parameters such as hole diameter, hole depth, and hole spacing to ensure that the processed aluminum profiles can meet the usage requirements.

5. Tapping processing
Tapping is a method of processing internal threads on aluminum. Tapping requires a special tapping machine to process threads inside the aluminum material through cutting. Tapping processing is often used to make connectors, fasteners, etc., which has the characteristics of firm connection and easy disassembly. Commonly used in industrial profiles (T slot, V slot).

6. Milling processing
Milling is a method of processing aluminum profiles using a milling machine. Through milling, planes, grooves, bosses, etc. of various shapes and sizes can be processed. Milling has the advantages of high processing accuracy and good surface quality, and is often used to make complex structural parts of aluminum profiles.
Tapping processing of Aluminum profile
In addition to the above six aluminum profile processing methods, there are other less commonly used processing methods. Due to different ways of using aluminum profiles, the processing methods may differ. However, a professional aluminum profile manufacturer will be very skilled in any processing method of aluminum profiles. According to the different needs of customers, Shenghai Aluminum can provide customers with various aluminum processing, saving customers' energy and expenses and ensuring product quality.
