Aluminium alloys offer a variety of advantages for sliding door applications, such as improved strength, corrosion resistance, and lightweight properties. Additionally, by incorporating recycled aluminium into these alloys, manufacturers can further enhance the sustainability of their products.

In conclusion, using recycled aluminium types like post-consumer aluminium, post-industrial aluminium, and aluminium alloys for sliding doors contributes to energy savings, lowers greenhouse gas emissions, and aligns with LEED certification goals. As our world moves towards greater environmental conservation and sustainability, embracing the use of recycled aluminium in sliding doors remains a responsible and promising choice.

Recycling Process of Aluminium

Aluminium is one of the most abundant and widely used metals on the planet. Due to its remarkable properties such as being lightweight, corrosion-resistant, and highly conductive, it is utilized in various industries like transportation, construction, packaging, and electronics. One major advantage of aluminium is its ability to be recycled and reused multiple times without losing its quality. Moreover, recycling aluminium saves up to 95% of the energy needed to produce it from raw materials. This article delves into the various stages involved in the aluminium recycling process.

Collection and Sorting

The first step in the recycling process is collecting and sorting aluminium scrap. This can be done through various channels, such as kerbside collection, bottle banks, or donation centers. Products made of aluminium, like cans, foil, and even car parts, can be recycled.

Once collected, the materials are sent to a sorting facility, where they are separated according to their composition. The sorting process relies on manual labor or automated systems utilizing machines such as vibrating screens, air classifiers, and magnetic separators. The use of eddy current separators is a popular method, as they can identify and separate aluminium from other materials based on their conductivity.

During this stage, contaminants like plastics, paper, and other metals are removed from the aluminium stream, ensuring a clean and homogeneous product for the subsequent steps.

Shredding and Separation

Following the sorting process, the aluminium scrap is transported to a recycling plant, where it undergoes more refining. The initial phase at the plant involves shredding the scrap metal into small pieces. This allows for a more convenient handling and storage, and it also facilitates the removal of any remaining contaminants.

After shredding, the fragments are passed through a series of separation devices to further eliminate impurities. These devices include magnetic drums that capture ferrous metals, eddy current separators to remove non-ferrous materials, and air classifiers that separate lighter contaminants such as plastic or paper.

Throughout this phase, the shredded aluminium is inspected and checked for quality. The pieces must meet specific size, shape, and purity criteria to ensure an efficient melting process in the next stage.

Melting and Purification

Once the aluminium scrap has been shredded and cleaned, it moves on to the melting phase. The scrap is placed in a furnace and heated to a temperature of about 660°C, the melting point of aluminium. This process is relatively energy-efficient, as it requires only 5% of the energy needed to produce aluminium from raw materials.

During the melting stage, the aluminium is exposed to a safe and controlled stream of air or inert gas, which helps remove any remaining impurities, such as paint or coatings. This process is known as “degassing” and is crucial for ensuring the end product’s quality.

Following the melting and purification process, the molten aluminium is subjected to a treatment called “fluxing.” This step involves introducing different compounds, usually salt-based, to the molten metal. These compounds react with impurities and contaminants, causing them to separate from the aluminium and form a layer of slag on the surface. The slag is then skimmed off and discarded.

Formation of Aluminium Billets

Once the molten aluminium has been purified, it is cooled and solidified into different shapes and sizes, such as ingots, sheets, or rolls. The most common form of recycled aluminium is billets, which are cylindrical or rectangular bars that can be further processed into various products.

To create billets, the molten aluminium is poured into molds and allowed to cool. The solidified billets are then removed from the molds and can undergo heat treatment to achieve a specific set of properties, such as strength or ductility, depending on their intended use.

Finally, the recycled aluminium billets are transported to manufacturers who process them into new products like cans, foils, car parts, construction materials, or other aluminium-based applications. This entire process demonstrates the significant environmental and economic benefits associated with recycling aluminium, ultimately contributing to a more sustainable manufacturing industry.

There are several different casting methods applicable for the production of aluminium sliding doors, such as die casting, gravity die casting, and sand casting.

Die casting is a high pressure casting method suitable for creating intricate and detailed aluminium components. In this process, the aluminium alloy is injected into a mould cavity under high pressure, resulting in a uniform and consistent final product with excellent dimensional accuracy.

Gravity die casting involves pouring molten aluminium into metallic moulds and allowing gravity to aid in the distribution of the material within the mould cavity. Sand casting, on the other hand, uses sand moulds to form the desired shapes, making it an effective method for creating large or complex components.

Casting methods are particularly useful for creating various components of aluminium sliding doors, such as handles, locks, hinges, and other intricate parts.

Roll Forming Method

Roll forming is a continuous bending process employed to manufacture aluminium sliding door sections from recycled aluminium. The process involves feeding a long strip of recycled aluminium through a series of roll forming machines, which gradually bends and forms the material into the desired cross-sectional profile.

The roll forming method is particularly suited to the production of long, slender, and lightweight sections that can be made from a single continuous sheet of recycled material. This method is cost-effective and efficient, especially for high-volume production of sliding doors, as it minimizes waste material and creates consistent profiles.

Once the roll-formed sections have been manufactured, they can be cut to size, finished, and assembled into the final sliding door product.

Joining and Assembly Techniques

The final step in the manufacturing of recycled aluminium sliding doors is the joining and assembly of the various components together. To ensure the strength, durability, and rigidity of the assembled door, several techniques can be used, such as welding, mechanical fastening, and adhesive bonding.

Welding is a common method for joining aluminium sections and components, providing a strong and permanent bond. Various welding techniques, such as TIG (tungsten inert gas) welding and MIG (metal inert gas) welding, can be employed to create high-quality joints that maintain the structural integrity of the sliding door.

Mechanical fastening methods, such as screws, rivets, and bolts, are also commonly used to assemble and secure aluminium sliding door components. This method is advantageous since it allows for easy disassembly and maintenance of the door components.

Adhesive bonding is another option for joining aluminium parts, often used in combination with mechanical fastening to strengthen the bonds and improve the overall aesthetic of the final product.

In conclusion, the manufacturing process for recycled aluminium sliding doors involves several stages and techniques, such as extrusion, casting, roll forming, and joining and assembly methods.
