How Aluminium is Produced from Raw Materials and Our Manufacturing Process
We all know that aluminium is used in many things in modern life, but how is it produced? The production of aluminium begins with the extraction of raw materials, mainly from bauxite. This ore undergoes a refining process to produce alumina (aluminium oxide), which is then smelted using electrolysis to isolate pure aluminium. The molten aluminium is then cast into ingots, which form the main raw material for other aluminium-based products.
At Foshan Golden Honor Building Materials Co., Ltd., we focus on the quality of our products, so we carefully select our raw materials and source high-purity aluminium ingots from Malaysia and Australia, as these ingots form the basis of our high-quality aluminium products. After the ingots are sourced, we reprocess them, and our manufacturing process involves the following key steps:
1. Melting and Alloying：
The imported aluminium ingots are melted in our state-of-the-art furnaces. At this stage, precise amounts of magnesium and other trace elements are added to enhance the mechanical properties of the aluminium, such as strength, corrosion resistance and machinability. We strictly avoid using scrap or recycled aluminium, strictly control quality and provide aluminium products that meet the highest standards to ensure that the material purity and performance are not compromised.
2. Casting into extrusion billets：
Molten aluminum alloy is cast into cylindrical billet aluminum bars suitable for extrusion. We conduct strict quality checks, including spectral analysis, to verify the chemical composition and eliminate impurities.
3. Extrusion process：
We have more than 15 extrusion lines. We use hydraulic extruders to heat the billet and press it through precision dies to form aluminum profiles customized according to specific sizes and cross-sectional designs. Whether it is aluminum tile trim, aluminum floor strips, aluminum skirting board, aluminum stair nosing strips, they can be extruded with specific dies, and the structure of the aluminum profiles will be further stabilized by advanced cooling and aging treatments.
4. Quality Commitment：
By controlling every step from raw material selection to aluminum production, we ensure that our products meet international standards (such as ASTM, EN). After aluminum extrusion, we will also perform various surface treatments, such as polishing, brushing, oxidation, powder spraying, thermal transfer, electrophoresis and other processes to ensure that the surface treatment of the aluminum is exquisite, durable, wear-resistant and will not fade.
Application of our aluminum products：
We specialize in the production of aluminum building materials, including:
Aluminum tile trims, aluminum floor transition strips, aluminum skirting boards, aluminum handles, aluminum LED profiles, etc. These products are widely used in construction, interior design and industrial projects, with unique durability, beautiful versatility and meet the needs of the public.
By combining high-quality raw materials, advanced technology and strict quality control, we provide aluminum building materials solutions. For more details, please visit Foshan Golden Honor Building Materials Co., Ltd., your trusted partner for high-quality aluminum manufacturing.
