Advantages of using powder coating for surface treatment of industrial aluminum profiles
There are three processing methods for industrial aluminum profiles: anodizing, electrophoretic coating and powder spraying. Each of them has its own advantages and occupies a considerable market share.
What extrusion molds are used for hollow aluminum profiles and solid aluminum profiles?
Hollow aluminum profiles and solid aluminum profiles are both extruded after heating aluminum rods. The difference between the two lies in the use of different extrusion dies. So what specific extrusion dies are used for the two profiles?
The Functions of Different Holes on Industrial Aluminum Profiles
No matter what specification of industrial aluminum profile it is, there are holes of various sizes on its cross-section. So what are the functions of these holes? Let’s learn about it together.
What is Aluminum Sliding Door
Aluminium sliding door is a type of door system that consists of two or more panels, typically made of aluminium or aluminium alloy frames with glass or other infill options. These panels are mounted on horizontal tracks, allowing the door(s) to slide open and closed. The major components of aluminium sliding doors include the following parts:
The main causes of particles on the surface of extruded aluminum profiles
What are the main causes of particles on the surface of extruded aluminum profiles? In the extrusion production of aluminum profiles, there are some small particles adsorbed on the surface of the profile to varying degrees, which feel tactile when touched, affecting the surface beauty of the oxidation, electrophoretic painting and spraying profiles, and reducing production efficiency and yield.
Reasons and solutions for blackening and slag inclusion defects in aluminum extrusion profile billets
In order to solve the problems of black spots and slag inclusions in finished aluminum profile products, reduce the amount of scrap, and improve the yield rate, the Technology Department conducted a large number of investigations.
5 points of knowledge about aluminum extrusion profiles
Extrusion is a plastic processing method that applies external force to the metal blank placed in the container (extrusion cylinder) to make it flow out from a specific die hole to obtain the desired cross-sectional shape and size.
Types of Aluminum Profiles
Aluminum profiles can be divided into 9 series from 1xxx to 9xxx based on the different content of aluminum components and the different ratios of the added alloy components.
Main factors causing industrial aluminum profiles to be black
Industrial aluminum profiles are an alloy material with aluminum as the main content. Aluminum materials with different cross-sectional shapes are obtained by hot-melting and extruding aluminum rods. However, the proportions of the added alloys are different.
How to solve the problem of rough and pitted surfaces of aluminum profiles
The reason why aluminum profiles appear pitted or pitted may be an oxidation reaction. Products made of pure aluminum products generally do not have this phenomenon. It may be that the aluminum material is impure. Such aluminum materials are prone to oxides during production. Speckled white spots form. It is recommended to process it into alloy aluminum during processing. The combined components can change the performance, hardness and corrosion resistance of the material. It can also be surface treated such as anodizing, electroplating, baking paint, sandblasting, etc. Mostly, the surface of aluminum alloy profiles is dull and not smooth, and after oxidation, the surface becomes dark black (does not reflect light).
