Step 1: Selection of raw materials Industrial aluminum profiles are a kind of industrial frame profiles obtained by heating aluminum bars and extruding them with molds, while aluminum bars are made by melting and casting aluminum ingots, which are called raw materials of industrial aluminum profiles; The raw materials will directly affect the performance of industrial aluminum profiles. Step 2: Heat the aluminum bar The temperature control shall be ensured during the heating treatment of aluminum bar. If the temperature is too high or too low, the hardness of the finished product will be directly affected, so the temperature must be strictly controlled during the heating and cooling process; Step 3: Mold design Industrial aluminum profile is the final product of aluminum bar extruded by die after heating, and the die is an appliance with high-precision specifications designed according to requirements, which is used to extrude profile products of required specifications and sections; Step 4: Industrial aluminum profile extrusion For extrusion production, extrusion temperature is the basic and key technological factor. The extrusion speed must be carefully controlled during extrusion. Step 5: Straightening and correction of industrial aluminum profiles The straightness of aluminum profiles affects whether aluminum profiles can be used on mechanical equipment, so the straightness of aluminum profiles up to standard is one of the important standards for the quality of aluminum profiles. Generally, the extruded profiles need to be straightened for straightness. Step 6: Manual aging The aluminum profiles produced by extrusion have low hardness before aging and cannot be used as finished products. Therefore, generally speaking, aging must be carried out to improve the strength. Step 7: Sand blasting After extrusion, the surface of industrial aluminum profiles will have obvious stretch lines, and the surface micropores are large and relatively rough, so they must be sandblasted, Step 8: Surface oxidation treatment The surface of general aluminum profiles is treated with anodized silver white, which is elegant, beautiful and corrosion resistant. Generally, after this step is completed, the finished aluminum profiles will come out after cooling.
