Classification of Aluminum Extrusion Dies

1. Classified by the section shape of the die hole compression zone

It can be divided into: flat die, conical die, flat cone die, streamlined die and double cone die, etc., 

2. Classified by the types of extruded aluminum profiles.
It can be divided into bar molds, ordinary solid profile molds, wall panel molds, variable-section profile molds, pipe molds, and hollow profile molds.

3. Classified by the number of die holes

It can be divided into single-hole die and multi-hole die;

4. Classified by the extrusion method and process characteristics
It can be divided into hot extrusion die, cold extrusion die, hydrostatic extrusion die, reverse extrusion die, continuous extrusion die, water cooling die, wide expansion die, horizontal extrusion Machine molds and vertical extrusion machine molds, etc.

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.

Applications of aluminum alloys in the automotive industry
Aluminum alloys are widely used in the automobile industry and are mainly used in the manufacture of various parts of automobiles, including body, engine, suspension system, rims, etc. Here are some specific applications:

1. Body and frame: The lightweight properties of aluminum alloy make it widely used in the manufacture of body and frame. Using aluminum alloys can significantly reduce the overall weight of a car, thereby improving fuel efficiency and reducing emissions.

2. Engine parts: The high thermal conductivity and excellent corrosion resistance of aluminum alloys make it very popular in the manufacture of engine parts. For example, aluminum alloys can be used to make engine cylinder heads, pistons, and radiators.

3. Suspension system: The strength and stiffness of aluminum alloy make it widely used in the manufacture of suspension systems. Using aluminum alloys can improve the performance and durability of your suspension system.

4. Rim: The lightweight and beautiful appearance of aluminum alloy make it very popular in the manufacture of rims.

5. Other components: In addition to the above components, aluminum alloys are also used to manufacture other components of automobiles, such as fuel systems, braking systems, electrical systems, etc.

In general, the application of aluminum alloys in the automotive industry can improve the fuel efficiency, performance and durability of the vehicle, while also improving the aesthetics of the vehicle.
