Main technical content: 1. By heating the surface of the aluminum profile rather than the entire profile, we can reduce energy waste and prevent large physical property changes in the aluminum profile caused by large-area heating. This allows the aluminum profile to maintain its original physical properties, while its surface can achieve better ductility and toughness after heat treatment. This prevents significant changes in the overall performance of the aluminum profile due to subsequent embossing and reduces the generation of internal stress. 2. By setting up the pressing equipment, the distance between the upper and lower steel rollers is greater than the thickness of the aluminum profile, with a difference of less than 1mm. A more ideal range should be less than 0.2mm. This effectively prevents the aluminum profile from being damaged by roller pressing. The purpose is to maintain a good balance performance of the aluminum profile during transportation and embossing, preventing its deflection. The setting of the upper and lower glue rollers aims to effectively stabilize the aluminum profile through extrusion. Since the rollers are elastic, they can effectively prevent the deformation of the aluminum profile. To ensure that the upper and lower glue rollers do not have a significant impact on the aluminum profile, they are set up with a staggered arrangement in the horizontal direction, with a staggered distance of less than 1/10 of the diameter of the glue roller. The projections of the upper and lower glue rollers in the vertical direction overlap, with an overlap length of less than 1/10 of the diameter of the glue roller, which can achieve a better flexible clamping effect. 3. The embossing roller group is set up in the middle of the pressing equipment, which can effectively reduce the deflection effect of the embossing on the aluminum profile body. Moreover, the embossing blade is made of high-speed steel powder using a layered welding method, which ca
