All-aluminum home furnishings are becoming more and more popular with consumers for their stylish and beautiful appearance, energy saving, environmental protection and safety advantages, making more people curious about aluminum profiles that are easy to process and form, environmentally friendly, and lightweight.  Aluminum profile is what we have seen after undergoing complicated processes such as surface treatment of aluminum ingot and aluminum rod extrusion molding!  1, melting and casting    melting and casting is the first process in the production of aluminum, and the main processes include batching, smelting and casting.   1. Ingredients: According to the specific alloy grades to be produced, calculate the addition amount of various alloy components, and reasonably match various raw materials.    2. Melting: The prepared raw materials are added to the melting furnace according to the process requirements and melted, and the slag and gas in the melt are effectively removed through refining methods such as degassing and slagging.     3. Casting: The molten aluminum is cooled and casted into round casting rods of various specifications under certain casting process conditions through a deep well casting system.  2 , profile extrusion   Aluminum material is made of mineral aluminum element as the main raw material. The aluminum rod before molding is passed through a high temperature of 480℃ (detached from water), and then extruded through a mold.  Extrusion is an important method of profile forming. First, a mold is designed and manufactured according to the section of the profile product, and the heated round cast rod is extruded from the mold by an extruder.   The national standard is 6063, and an air-cooling quenching process and subsequent artificial aging process are used during extrusion to complete the heat treatment strengthening. Different grades of heat-treatable and strengthened alloys have different heat treatment requirements.  3, surface oxidation   After the aluminum alloy profile is extruded, its surface corrosion resistance is not strong, so it must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum material.  Main process:   a. Surface pretreatment: Use chemical or physical methods to clean the surface of the profile to expose the pure matrix, so as to obtain a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means.  B. Anodizing: The surface pretreatment of the profile will undergo anodization on the surface of the substrate under certain process conditions to form a dense, porous, and strong adsorption AL203 film.    C. Sealing: The pores of the porous oxide film formed after anodic oxidation are closed to enhance the antifouling power, corrosion resistance and wear resistance of the oxide film.    D. The oxide film is transparent: the oxide film is highly adsorbable before sealing, and some metal salts are adsorbed and deposited in the film pores to make the appearance of the profile appear in colors other than the natural color, such as black, bronze, golden and stainless steel.  4, all-aluminum household profile surface treatment powder   aluminum profile surface treatment mainly includes electrophoresis, anodizing, electrostatic powder spraying, fluorocarbon spraying, wood grain transfer and other process technologies. With its increasingly mature surface treatment technology, wide use, diverse colors, clear texture, and strong three-dimensional effect, all-aluminum household profiles can better reflect the natural look and texture of wood grain. It is also similar to panel furniture and is an ideal energy-saving and environmentally friendly alternative to traditional wood. material.  : For the healthy home life of the Chinese people, through the creation of all-house all-aluminum homes, thousands of households can have a healthy, safe and green home life!
