The aluminium door profile is an indispensable part in modern industry. With its superior performance and wide application, aluminium profiles have occupied an important position in multiple fields such as construction, transportation, aerospace, etc. As a lightweight material, the use of aluminium not only effectively reduces the overall weight of the product, but also enhances the stability and corrosion resistance of the structure. This article will deeply explore the technological process, market prospects and main application fields of aluminium door profile, aiming to provide readers with comprehensive industry insights.

I. Basic Concepts of Aluminum Industrial Profiles

Aluminum industrial profiles refer to various aluminum products made based on aluminum and its alloys through extrusion, cutting and processing. These products feature high strength, light weight, corrosion resistance and strong processability, and thus are widely used in various industries. Aluminum profile processing can achieve various shapes and sizes of design, such as square tubes, round tubes, flat bars, Angle profiles, etc., to meet the needs of different customers.

Ii. Extrusion Process of Aluminum Profiles

The production process of aluminium profiles mainly includes steps such as the smelting of aluminium ingots, extrusion forming, and surface treatment.

1. Melting and casting: Aluminum ingots are first melted in a furnace, with the temperature usually controlled at around 660°C. After melting, the molten aluminium will be cast into aluminium ingots in the mold. When it cools down, the initial aluminium profile billets will be formed.

2. Extrusion forming: Place the aluminum ingot into an extruder and use high pressure to extrude the molten aluminum through a die of a specific shape. This process can achieve complex and precise shapes. The extruded profiles need to be cooled and sheared to reach the required length.

3. Heat treatment: After extrusion, aluminum profiles usually need to undergo heat treatment to enhance their hardness and strength. Common heat treatment processes include quenching, aging, etc.

4. Surface treatment: The surface treatment of aluminum profiles can be carried out through methods such as anodizing, electrophoretic painting, and spraying, aiming to enhance their corrosion resistance and aesthetic appeal. This process not only extends the service life of aluminium profiles but also enables personalized design.
