Billet Aluminium
Characteristic
Aluminum billets are made from pure aluminum or aluminum alloys and serve as semi-finished products in the aluminum manufacturing industry. These billets are cast into cylindrical bars and are commonly used as raw materials for producing various aluminum products through extrusion, rolling, or mold casting processes.
Aluminum Billet Production Process
lngot Inspection.
The quality and composition of pure aluminum are thoroughly checked. Each aluminum ingot (Ignot) is randomly selected by our lab for testing before it proceeds to the melting stage.
Melting and Alloying
The raw aluminum is melted in a high-temperature furnace, transforming the ingot into liquid form. It is then mixed with other elements to create an alloy with specific properties that meet customer requirements.
Casting
The molten aluminum alloy is poured into molds with standard diameters to form the billet.
Cutting Billets
After heat treatment, the billets are cut into smaller sections, which will be used in the production of the final product. The cut billets are then processed using methods like cutting, milling, and grinding to create the finished product.
Cooling and Further Processing
Once the billets cool down, they are cut into standard-sized blocks. The size of the billets typically ranges from a few cm to several tens of cm in diameter and length, depending on customer requirements or the next production process. After cutting to specification, the billets undergo a quality check to ensure they meet the required standards and technical specifications.
Packaging Process
Secure both ends of the billets.
Place three straps through the wooden bar in the middle of the billets.
Packaging Requirements:.
5 straps per bundle for billets (2 straps at the ends, 3 straps in the middle).
All product quality label information must be filled out, and each billet should have a stamp.
Specification
Although DORICO Vietnam’s main products are 6060 and 6063 Aluminium Billets but we also supply a wide range of series 6xxx of other billets (6005, 6005A, 6061, 6360…) with diameters ranging from 4-7 inches. Furthermore, we have been preparing to be equipped with an 8-inch-diameter mold to meet the needs of industrial customers.
We recognize that each customer’s needs are distinct, thus we provide tailored solutions to fit their needs.
Application
Extrusion Aluminium
Characteristic
Aluminum extrusion is a metal manufacturing process in which aluminum billets are forced through a die to create specific shapes or final products. This process is commonly used to produce aluminum components with complex and detailed geometries.
Aluminum Extrusion Production Process
Preparing Aluminum Billet
The primary material for producing extruded aluminum is aluminum billet.
Heating the Aluminum Billet
The billet is heated to a specific temperature. This makes the billet more flexible and easier to extrude through the mold.
Extruding the Billet Through the Mold
Once the billet is heated, it is placed into an extrusion machine. A strong force pushes the billet through a mold with the required shape. The extrusion machine uses either a piston or a rotating shaft to force the billet through the mold. The mold can have various shapes depending on the requirements of the final product, such as square bars, U-shaped profiles, or round tubes.
Cooling the Product
After extrusion, the aluminum is cooled using water or air to lower the temperature and increase the strength of the product. This process helps maintain the shape and hardness of the aluminum after extrusion.
Cutting and Post-Extrusion Processing
Once the aluminum has cooled, it is cut to the desired length. Extruded aluminum products may also undergo additional processes such as trimming, drilling holes, grinding, or surface smoothing.
Surface Treatment
Extruded aluminum products often require surface treatment to protect them from corrosion and to enhance their appearance. Common surface treatment methods include anodizing, powder coating, or applying a layer of another metal.
Quality Control
Finally, the extruded aluminum products undergo thorough quality inspection to ensure they meet the standards for size, shape, and durability.
