Definition of aluminum extrusion process
Aluminum extrusion molding (or aluminum extrusion molding) is to apply strong pressure to the aluminum billet placed in the die cavity (or extrusion cylinder) to force the aluminum billet to produce directional plastic deformation and extrude from the die hole of the extrusion die.
aluminum extrusion manufacturer To obtain a plastic processing method for parts or semi-finished products with the required cross-sectional shape, size and certain mechanical properties.

Aluminum extrusion die
For product structure design engineers, although we don’t design aluminum extrusion dies, understanding the most basic extrusion die structure and the mechanism of how to shape different extrusions can help in extrusion When designing press parts, optimize the design to reduce mold cost and improve the production efficiency of extruded parts.

Advantages of aluminum extrusion process
Durable
Aluminum's corrosion resistance, corrosion resistance and weather resistance are one of its most significant advantages. Aluminum can rust and resist corrosion naturally without additional treatment. This is due to the presence of a thin, naturally formed protective film of aluminum oxide on its surface. Through anodic oxidation, its corrosion resistance becomes stronger.
Lightweight and strong
Aluminum is more than 33% lighter than steel, while retaining most of its strength. The tensile strength of most aluminum alloys is about 70-700 MPa, and the density is two-thirds less than steel.
Don't worry about the strength of aluminum extrusion parts. It can be used as structural parts in the construction industry and the automobile industry, and it is the best substitute for other metal materials.
Good thermal conductivity
The thermal conductivity of aluminum is very similar to copper, but the weight is much lighter.
Aluminum is an excellent heat conductor, and the profile design of aluminum extrusion can maximize the surface area of heat conduction and form a heat channel. A typical example is a computer CPU radiator, where aluminum is used to take away heat from the CPU.
Stylish appearance
Extruded aluminum can be painted, electroplated, polished, and anodized, which gives engineers a wider choice of appearance than other materials.
Wide range of applications
Basically any cross-section shape can be formed by aluminum extrusion. Therefore, the application range of aluminum extrusion is very wide. Engineers can design different cross-sections to meet the requirements of different application environments.
Easy secondary processing
Aluminum extrusions can be easily formed, cut, drilled, processed, stamped, bent and welded to suit specific purposes.
Absorb shock and deformation
In construction, aluminum extrusions can resist deformation caused by weather and building movement. In transportation, it can absorb impact energy. The aluminum extrusion maintains strength and flexibility under load and rebounds from impact.
