Aluminium extrusion mold for window and door materials

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.

Advantages of Aluminum Extrusion Dies

1.  The extrusion method can not only produce rods, pipes and other products with simple cross-sectional shapes, but also hollow and solid products with complex cross-sectional shapes.

2. The production flexibility of the extrusion method is very large. Products with different shapes and sizes can be produced only by changing the mold. The mold replacement time is short and the production efficiency is high, which is of great significance for the production scale of small batches.

3. The dimensional accuracy of extruded products is far better than that of rolling and die forging, and the surface roughness is better, so it can be processed without processing and become a finished product.

4.  The mechanical properties of extrusion products are good, especially for aluminum and aluminum alloy products, the extrusion effect is that after quenching or aging, the longitudinal properties of the products are higher than those of rolling and die forging.

5. Compared with rolling, extrusion equipment has compact structure, less land occupation, less infrastructure cost, simple operation and easy maintenance.

6. It is easy to realize semi-automation or automation.
