thermal break door extrusion dies

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 cav…
