Aluminum profiles are a material widely used in indoor and outdoor decoration, building structures and other fields. It has the characteristics of light weight, good thermal conductivity and strong plasticity. In the production process of aluminum profiles, multiple processes are required to form aluminum profiles of various shapes and specifications.
1. The following are common aluminum profile production processes
1. Hot extrusion:
Hot extrusion is a commonly used aluminum profile production process. During the extrusion process, the aluminum material is pushed into the extruder and extruded from the die orifice through high pressure to form the required cross-sectional shape. Aluminum profiles of various complex shapes can be produced through the extrusion process.
It usually includes the following steps:
Material preparation: Select appropriate aluminum alloy materials and perform pretreatment as necessary, such as cleaning and removing scale.
Heating: Heating aluminum to the right temperature so that it becomes malleable and easy to extrude.
Extrusion: The preheated aluminum material is put into the extruder and extruded through the orifice of the die through high pressure to form the desired cross-sectional shape.
Cooling: The extruded aluminum profile enters the cooling table and is rapidly cooled by water cooling to enhance its mechanical properties.
Cutting and Trimming: The cooled and solidified aluminum profiles are cut to the required length and trimmed to remove burrs and irregular edges.
2. Cold extrusion:
Cold extrusion is an extrusion process performed at room temperature. By applying pressure to the cooled aluminum material, it is extruded from the die to form an aluminum profile of the desired shape. Cold extrusion is often used to produce aluminum profiles with special requirements, such as pipes, filaments, etc.
The process includes the following steps:
Material preparation: Select appropriate aluminum alloy materials and perform pretreatment as needed.
Heating (optional): If desired, heat treat the aluminum to improve its plasticity.
Cold extrusion: Put the aluminum material into a cold extrusion machine and apply high pressure at normal temperature to form the required shape through the die.
Cutting and trimming: Cut the cold-extruded aluminum profiles as required and trim them to obtain a smooth surface.
