Custom Industrial Aluminum Extrusion Profiles

How to correct the straightness of industrial aluminum extrusions profiles after extrusion?

Industrial aluminum extrusion profiles are widely used in industrial machinery, construction machinery, ships and deck machinery, offshore equipment, mining and metallurgical machinery and other fields due to their light weight, high strength, corrosion resistance and easy processing. In these applications, the straightness of industrial aluminum profiles is one of the key indicators to measure its quality, which directly affects the assembly accuracy, service life and safety of the product. Therefore, straightness correction after extrusion is not only a basic condition to meet customer needs, but also the key to improving the competitiveness of corporate products.
After extrusion, aluminum profiles often have certain bending deformation due to factors such as uneven metal flow and mold wear. Thermal straightening is an effective preliminary correction method. Its principle is to use the plasticity of aluminum at high temperature to restore it to a straight state by applying external force. Our company is equipped with advanced heating equipment and precision straightening tooling, which can accurately control the heating temperature and straightening force to ensure efficient straightness correction without damaging the internal structure of the aluminum.
After thermal straightening treatment, the straightness of the industrial aluminum extrusion profile has been initially improved, but it often requires further fine-tuning. At this time, we use cold straightening or mechanical correction technology. Cold straightening is to apply tension at both ends of the profile and use the elastic recovery ability of the material to gradually eliminate small bends; while mechanical correction uses a dedicated correction machine to achieve fine adjustment of the straightness of the profile through precise bending and rebound control. Both methods require operators to have high professional skills and experience to ensure the accuracy and safety of the correction process.
The straightness correction process is a closed-loop control system that cannot be separated from high-precision detection methods. Our company is equipped with industry-leading detection equipment, such as three-coordinate measuring machines, image measuring machines, etc., which can achieve high-precision measurement of the straightness of industrial aluminum extrusions with error control at the micron level. The detection data is fed back to the correction link in a timely manner to guide the adjustment of the correction strategy to ensure that the straightness of each batch of products can meet or even exceed customer requirements and international standards.
