9 Steps In Aluminium Extrusion Processing Process

September 24,2021.

Step 1: Selection of raw materials

Industrial aluminum profile is an industrial frame profile obtained by heating aluminum rods and extruding molds, while aluminum rods are made by melting and casting aluminum ingots, which are called industrial aluminum profile raw materials; and the raw materials will directly affect the industry Aluminum profile product performance.


Step 2: Aluminum rod heating

The heating treatment of the aluminum rod should ensure the temperature control. If the temperature is too high or the temperature is too low, it will directly affect the hardness of the finished product, so the temperature must be strictly controlled during the heating and cooling process;


Step 3: Mold design

  Industrial aluminum profile is the final product of aluminum rod extruded through a die after heating, and the die is an appliance with high-precision specifications designed according to requirements, used to extrude profile products of required specifications and cross-sections;


Step 4: Industrial aluminum extrusion

For extrusion production, extrusion temperature is a basic and critical process factor. The extrusion speed must be carefully controlled during the extrusion process.


Step 5: Industrial aluminum profile straightening correction

The straightness of the aluminum profile affects whether the aluminum profile can be used on mechanical equipment, so the straightness of the aluminum profile meets the standard, which is one of the important criteria for the quality of the aluminum profile. Generally, the extruded profile needs to be straightened.


Step 6: Artificial aging

The aluminum profile produced by extrusion has low hardness before aging and cannot be used as a finished product. Therefore, in general, it must be aging to increase its strength.


Step 7: Sandblasting

  Industrial aluminum profile after extrusion molding, the surface will have obvious stretch marks, and the surface has large micropores and relatively rough, which must be sandblasted.


Step 8: Surface oxidation treatment

Generally, the surface of aluminum profile is treated with anodized silver white, which is elegant and beautiful and anti-corrosion. Generally this step is done, after cooling, the finished aluminum profile will come out.


Step 9: Packaging

Due to the very high quality requirements of industrial aluminum products, the overall aesthetics of the appearance are very particular, so the requirements for later packaging are very strict.
