Aluminum Template is a formwork system used in building construction, mainly made of aluminum alloy materials, and is widely used in the construction of concrete structures. Aluminum template is a lightweight, high-strength formwork system, mainly used for concrete pouring and molding. It can be quickly assembled and disassembled through standardized design and modular combination, and is suitable for various building structures, especially high-rise buildings and prefabricated buildings.
Features
- Lightweight: Aluminum Template has a low density and light weight, which is convenient for transportation and on-site operation, reducing the labor intensity of construction workers.
- Resistance to corrosion: The aluminum template will develop a thick layer of oxide on its surface, which will help it withstand the effects of chemicals and humid environments and prolong its useful life.
- High strength: Aluminum templates that have undergone specific treatment have a high mechanical strength that allows them to endure impact and pressure during the pouring of concrete while maintaining construction safety.
- Free combination: To accommodate a range of intricate construction scenarios, the Aluminum Template system's standardized modules can be freely mixed based on the needs of the building structure.
- Strong adaptability: By modifying the module combinations, Aluminum Template may satisfy the building requirements of various parts, whether it be a wall, beam, column, or floor.
- Efficient construction: The modular design of Aluminum Template simplifies the installation and disassembly process and improves construction efficiency, which is particularly suitable for large-scale, standardized construction projects.
Manufacturing Process
- Alloying and melting:
A suitable quantity of alloying elements (such as silicon, magnesium, etc.) are added to the recycled aluminum during the melting process increase its strength and corrosion resistance. High-temperature melting is used to reprocess recycled aluminum, heating it to approximately 660°C until its melting point reaches this temperature and turns liquid. This alloying treatment can improve the mechanical properties of the aluminum template, improving performance during the construction process.
- Molding and casting:
For molding, the liquid aluminum alloy is poured into a precision casting mold. In this procedure, the aluminum alloy liquid is injected into the mold in accordance with the aluminum template's design specifications, and once it cools, the aluminum template's basic shape is created. Strict temperature and casting time control are necessary for this step in order to guarantee a uniform aluminum template structure and prevent flaws like pores or cracks. In general, the cast aluminum template's dimensional accuracy error is kept within ±0.5mm.
- Curing and heat treatment:
After molding, the aluminum template must be heated to increase its hardness and strength. The aluminum alloy can achieve an optimal crystal structure by regulating the heat treatment temperature and duration, which will increase the aluminum template's compressive strength and resistance to corrosion. The hardness value of heat-treated aluminum templates is typically higher than that of regular aluminum materials, reaching HV 60 or higher.
- Treatment of the surface:
The aluminum templates will undergo surface treatment to increase their resilience to corrosion and durability. Typical surface treatment techniques include spraying and anodizing. By creating a thick oxide layer on thealuminum template's surface, anodizing can improve its resistance to water and corrosion. The oxide film's thickness can be regulated between 10 and 50 μm, depending on the surface treatment technique, and this effectively stops moisture and chemical erosion.
