Otalum is one of the leading manufacturers of customed aluminium extrusion products in Southeast-China, Australia, South America and Southeast-Asia, offering a wide range of production capacities in aluminium extrusions, finishing and fabrication. Aluminium is a material combining the characteristics of light, strong, anti-rust, recyclable and economical, which provides the designers and manufacturers with precious choices to maintain a balance between function and cost.
Otalum's aluminium extrusions profiles are mainly used for a wide variety of markets and applications, such as building and construction, machinery, automotive, furniture, LED, heat sink. These aluminium profile sections not only offer good functions but also perform well during actual use. All our extruded profiles can be produced with the processes of mill finish, anodizing, powder-coating, PVDF painting and wood finishing. Thermal break profiles are also available at Otalum and we also offer a full range of fabrication processes.
Various types of aluminum extrusion profiles can be created with different thicknesses. These extruded profiles can have a variety of complex void spaces, which are necessary for end-use applications. In order to facilitate various automation applications and meet any performance and weight requirements, a variety of internal voids can be used. The most common type of aluminum profile is hollow beam profile, which is just a variation of square profile. There are other contour types, such as triangular, single radius and L-shaped contours.
Aluminium extrusion transforms aluminum alloy into a variety of products suitable for consumers and industrial markets. Aluminum profiles have many uses in electronics, automobiles, public transportation, bridge deck paving, telecommunications, solar energy, renewable energy and other industries.
The extrusion process makes full use of the excellent ductility of aluminum. The aluminum alloy billet is heated to soften it, and then pressed into a special steel mold with a hydraulic press or a punch under high pressure to form a shape. The result is an aluminum sheet that maintains the specific shape of the mold.
Different alloys in different states can make extruded aluminum profiles to meet the various needs-from household items to space vehicles. Basically, aluminum profiles can be extruded from any deformable aluminum alloy (even casting) in one way or another. However, metals need special flow characteristics to flow through the holes and cavities of the matrix under high temperature compression. Therefore, metals should: fill all the holes at the exit of the matrix at the same high speed, provide the required micro-structure, reach the predetermined strength and other characteristics and shape the best surface quality.
Therefore, special aluminum alloys specifically for pressing (extrusion) are being developed. In this way, the chemical composition of these alloys is optimized to make them most suitable for the conditions of the pressing process and to ensure the required quality of the molded products.
Aluminium extrusion is a process where aluminium alloy is transformed into items with a specific cross-sectional outline for subsequent wide-ranging uses. A simpler definition would refer to aluminium being squeezed all the way through an orifice.
Aluminum extrusion is defined as a process by which aluminum is forced to flow through a shaped opening in a die. A powerful press pushes the aluminum through the die and it emerges from the die opening. The outcome is a long profile with the same shape as the opening in the die.
Aluminum extrusions can be made as strong as what we need and, due to the nature of the extrusion process, the strength can be focused on where it is really needed by increasing wall thicknesses and adding internal reinforcement in the profile design. Cold-weather applications are well, as profile aluminium extrusion becomes stronger as temperatures fall.
Extrusion is defined as the process of shaping material, such as aluminium, by forcing it to flow through a shaped opening in a die. Cast aluminium is the resulting product created after molten aluminum is poured into a mold.
Extrusion is defined as the process of shaping material, such as aluminum, by forcing it to flow through a shaped opening in a die. Extruded aluminium emerges as an elongated piece with the same profile as the die opening.
