Manufacturing Process for Aluminium Sliding Doors
Aluminium sliding doors are popular choices in residential and commercial structures due to their durability, low maintenance requirements, and energy efficiency. The manufacturing process of these doors involves various stages, including the preparation of raw materials, extrusion of aluminium profiles, fabrication, and assembly. This article will discuss each phase in detail, providing an understanding of how aluminium sliding doors are made.
Aluminium is the primary raw material used in the production of sliding doors. It is a lightweight and corrosion-resistant metal that can be easily extruded and processed into different shapes and sizes. In addition to aluminium, other raw materials such as glass, weather seals, rollers, handles, and hardware components are used in the manufacturing process.
To make aluminium sliding doors, manufacturers source the aluminium from foundries or mills. High-quality aluminium alloys are often utilized, with the most common types being 6063 and 6061. These alloys offer excellent processing capabilities and mechanical properties, which are crucial in creating strong and durable doors. The aluminium is usually supplied as a billet, a semi-finished cylindrical form, that is later converted into profiles through an extrusion process.
The glass used in aluminium sliding doors is typically tempered or laminated for enhanced safety and strength. Tempered glass is treated through a heat process to increase its toughness, while laminated glass comprises two or more layers of glass bonded together with a plastic interlayer. Both types can provide high levels of insulation and soundproofing.
Extrusion of Aluminium Profiles
Extrusion is a crucial step in the manufacturing process of aluminium sliding doors. The process starts by heating the aluminium billets to a temperature between 400°C and 550°C, making them more malleable. The heated billets are then placed into the extrusion press, which comprises a die, container, and ram.
The die acts as a mold, dictating the shape and size of the aluminium profile to be produced. The container holds the heated billet in place, while the ram applies pressure, forcing the molten aluminium through the die. As the aluminium exits the die, it cools down and solidifies into a profile with the desired shape and dimensions.
To ensure the profiles have the required mechanical properties, they are subjected to ageing treatments, which could be natural or artificial. Natural ageing occurs at room temperature, while artificial ageing involves placing the profiles in a temperature-controlled environment to speed up the hardening process.
In the fabrication stage, the aluminium profiles are cut, machined and prepared for assembly. Cutting involves trimming the profiles to the required lengths and removing any excess materials. Joints and angles are created using specialized machinery, such as CNC milling machines and mitre saws.
Machining involves drilling holes for fasteners, creating spaces for rollers, handles and other hardware components, as well as milling grooves for gaskets and seals. Once the profiles have been cut and machined, they are subjected to a surface treatment, such as anodizing, powder coating, or painting. These treatments not only improve the profiles’ aesthetic appeal but also enhance their resistance to corrosion, scratching, and other types of wear.
The final stage in the manufacturing process for aluminium sliding doors is assembly. During this stage, the aluminium profiles, glass panels, rollers, handles, and other hardware components are assembled to create the final product. The profiles forming the frame are joined using fasteners, such as screws or bolts.
The glass panels are secured in place using glazing gaskets and silicone sealants, ensuring a watertight fit. The rollers, which facilitate the sliding mechanism of the doors, are attached to the bottom of the door profiles, while the handles and locks are fixed to the appropriate locations. Weather seals, such as brush or rubber strips, are also installed around the door frame to improve insulation and prevent drafts.
Once the aluminium sliding doors are fully assembled, they undergo a thorough quality inspection to ensure proper function and craftsmanship before being packaged for shipping and installation.
