aluminium extrusion mold for frame materials profile

Architectural aluminum profiles are a material that we often use in decoration, and they are widely used and very popular. Architectural aluminum profiles not only have the advantages of simplicity, practicality, and good results, but also have the characteristics of corrosion resistance.

Characteristics of architectural aluminum profiles:

1. Compared with other materials, aluminum profiles have higher corrosion resistance and will not deform due to moisture.

2. Architectural aluminum profiles have good ductility and can be made into various products through pressure processing methods such as extrusion and stretching.

3. Architectural aluminum profiles have good hardness, high tensile strength, and strong wind pressure resistance, making them suitable for high-rise buildings.

4. Architectural aluminum profiles can be produced in various colors through surface treatment processes such as oxidation coloring, electrostatic spraying, and fluorocarbon spraying, with excellent decorative and aesthetic effects.

5. Architectural aluminum profiles can be recycled and reused after use, with low energy consumption and can be recycled repeatedly, avoiding resource waste and environmental pollution.

Structure of Aluminium Extrusion -Hollow Mold and Solid Mold

Aluminum profile extrusion dies can be divided into solid dies and hollow dies according to the shape of the extrusion section, and hollow dies can be divided into single-hole dies and multi-hole dies.

Hollow mold: It consists of two parts, the upper mold and the lower mold.

The general function of the upper mold is to guide the flow and position the hollow part of the hollow profile.

The lower mold is the outer surface working belt and empty knife.

Solid mold: Only one piece of mold including flow guide and working belt.

The working principle of extruded aluminum profile mold mainly includes the following steps:

1. Preheating: First, preheat the aluminum profile and extrusion die to a certain temperature.

2. Extrusion: The preheated aluminum profile is put into the extruder and extruded through the cavity of the mold under high pressure to form the desired profile shape.

3. Cooling: The extruded aluminum profile needs to be cooled to fix its shape.

4. Cutting: The cooled aluminum profile is cut to the required length.

5. Heat treatment: In order to improve the hardness and strength of aluminum profiles, heat treatment is usually required.

6. Surface treatment: As needed, the surface of the aluminum profile may need to be frosted, anodized, electrophoretic painted, powder sprayed, etc.

In the whole process, the function of the extrusion die is to determine the shape of the extruded aluminum profile through the shape of its internal cavity during the extrusion process. The design and production of molds directly affect the quality and production efficiency of aluminum profiles.
