Main cause of surface damage of aluminum profiles　 1. There are impurities attached to the surface of the ingot or segregation of the ingot composition. When there is a large number of segregation floats on the surface of the ingot and the ingot is not homo...

In the extrusion production, there will be defects commonly known as "tail shrinkage" in the semi-finished parts of the cut head and tail after the head and tail are inspected, and the mechanical properties of the type bar containing the tissue cannot meet the...

Commonly used metal edge materials mainly include the following, which are widely used in different fields due to their respective characteristics: 1. Stainless steelFeatures: strong corrosion resistance, high strength, bright appearance, easy to clean and ma...

1. Material selection: balance between performance and costCopper vs aluminumCopper: The thermal conductivity is about 400 W/m·K, and the thermal conductivity is the best, but it has a high density (8.96 g/cm³) and high cost, and is mostly used in ...

1. Stretching must be cooled to below 50 degrees in the aluminum alloy profile can be moved to the stretching frame for stretching operation, the temperature is too high, that is, stretching will not only burn the human body, scald the wool top, but also becau...

1. Use effective mold repair to improve the flatness of the productMold repair is the most commonly used solution for poor flatness of extruded material at home and abroad, the advantage of this method is that the scope of application is wide, basically all ex...

The improvement of the life of the extrusion die depends on the perfect link between the design, manufacturing, use and subsequent maintenance processes. Relying on a single link can not effectively achieve the goal, through the effective integration of each link, I believe that the mold life can be improved accordingly.

1. High-pressure water cuttingTechnology: Cutting materials using high-pressure water streams.Pros: Provides precise cutting and clean and smooth edges. The powerful water jet prevents the aluminum sideband from deforming and ensures high precision.Applicabili...

1. Use effective mold repair to improve the flatness of the product　　Mold repair is the most commonly used solution for poor flatness of extruded material at home and abroad, the advantage of this method is that the scope of application is wide, basically ...

1. The quality of heat treatment of aluminum extrusion die directly affects the service life of the extrusion die, and the mold is tempered many times after quenching "+" to meet the hardness requirements. Quenching is to improve the hardness of the mold, and ...
