Casting is the beginning of aluminum profile preparation process. Need to carry out the ingredients first, see the type and characteristics of aluminum profiles, so as to determine the amount of various metal components added, reasonable configuration of various raw materials. Secondly, it is melted, and the finished material is melted in the melting furnace. This step should be performed according to the technical requirements. The impurities such as slag and gas in the melt are removed by the essence technology. After the above steps are finished, casting is carried out. The melted materials are processed by casting technology and cooled to form round casting rods of various specifications.
Kneading is the second step in making aluminum profiles. Kneading makes the profile become the shape we need. First, according to the shape of the product, the mold is made. The heated round casting rod is squeezed from the mold by the kneading machine. In kneading, air cooling quenching technology and artificial aging process are also needed to complete the heat treatment and strengthening. The thermal disposal criteria of the reinforced alloy with different standards are different.
The third step of the aluminum profile is coloring. First, the surface is pre-disposed, and the surface is cleaned by chemical or physical means, so as to ensure a fine and flawless artificial oxide film. It can also be mechanically made into a mirror surface or matte state. Then anodized, the surface of the pre-disposed profile, under certain technical conditions, the matrix surface of the anodized, the generation of a film layer. Finally, the pore sealing is used to close the pore of the porous oxide film generated after anodic oxidation, so as to enhance the performance of the oxide film. The oxide film is transparent, using its strong adsorption, adsorption and accumulation of some metal substances in the membrane hole, can make the aluminum surface in addition to silver, but also can show black, bronze, gold and many other colors.
