Extruded aluminum profile is a common metal processing method. It uses pressure to extrude aluminum materials into profiles of different shapes after heating them to a certain temperature.
This processing method has the advantages of high efficiency, economy, and environmental protection, so it is widely used in construction, transportation, electronics, furniture and other industries.
The following will introduce the principles, advantages and application fields of extruded aluminum profiles.
The principle of extruded aluminum profile
The principle of extruded aluminum profile is to use the plasticity of metal materials, apply pressure after heating, and use the mold to make the metal material pass through a certain shape orifice to obtain the required profile.
The principle of extruded aluminum profile can be simply summarized as: thermal expansion and contraction and metal rheology.
1. Thermal expansion and contraction means that during the heating process, the metal material will expand due to the increase in temperature, and will contract during the cooling process.
Using this principle, the expansion and contraction of the metal material can be controlled by adjusting the shape and size of the mold to obtain the required profile.
2. Metal rheology refers to the fact that after heating, the metal material has better plasticity and deformability due to the change of its internal structure.
During the extrusion process, the metal material will be subjected to pressure, and under the guidance of the mold, it will flow into the desired shape orifice to form a profile.
The principle of extruding aluminum profiles
The main steps of extruding aluminum profiles are: profile design, mold manufacturing, extrusion processing and subsequent processing.
1. Profile design is the first step in extruding aluminum profiles. It needs to determine the cross-sectional shape, size and wall thickness of the profile according to the use requirements and stress analysis.
Well-designed profiles can improve the performance and service life of the product.
2. Mold manufacturing is a link in extruding aluminum profiles. It needs to manufacture molds with certain shapes and sizes according to the design requirements of the profiles.
The manufacture of molds needs to consider factors such as material selection, heat treatment and processing, as well as the accuracy and service life of the mold.
3. Extrusion processing is to put the heated metal material into the extruder and extrude it into the desired profile by applying pressure.
During the extrusion process, it is necessary to adjust parameters such as heating temperature, extrusion speed and pressure according to the properties of the metal material and the requirements of the profile.
4. Subsequent processing is a step in extruding aluminum profiles, which mainly includes cooling, trimming, cutting and surface treatment.
Cooling is to place the extruded profile in a suitable environment to cool it quickly to ensure the dimensional stability of the profile.
Trimming is to trim and shape the profile to remove burrs and unevenness on the surface.
Cutting is to cut the profile to the required length.
