Overview of the three major production processes of the aluminum alloy profiles of the Great Wall custom aluminum box materials

April 19, 2023

The aluminum alloy profile of the aluminum alloy raw material is used as an essential material for the production of aluminum alloy boxes, instrument boxes, air boxes, tool boxes and aluminum alloy packaging boxes. Therefore, its production process largely determines the quality of the produced aluminum alloy boxes. The pros and cons. The aluminum alloy profiles mainly include three processes of casting, extrusion and coloring.
First, casting: the first process of aluminum alloy profile production:
It mainly includes the following three processes:
1. Ingredients: Calculate the amount of various alloy components according to the specific alloy grades that need to be produced, and reasonably match various raw materials.
2. Smelting: The raw materials are added to the melting furnace for melting according to the process requirements, and the impurities and gases in the melt are effectively removed by means of degassing and slag refining.
3. Casting: The molten aluminum liquid is cooled and cast into round casting rods of various specifications through a deep well casting system under certain casting process conditions.

Second, extrusion: means of forming aluminum alloy profiles:
First, the mold is manufactured according to the profile product, and the heated round cast rod is extruded from the mold by an extruder, and an air-cooling quenching process and an artificial aging process after the extrusion are used to complete the heat treatment strengthening.

Third, color: extruded aluminum alloy profiles, the surface corrosion resistance, wear resistance and appearance of the appearance is not strong, usually using oxidation for surface treatment.
Oxidation treatment includes the following three processes:
1. Surface pretreatment: The surface of the aluminum alloy profile is cleaned by chemical or physical methods to expose a pure matrix to facilitate the obtaining of a complete and dense artificial oxide film.
2. Anodizing: After surface pretreatment, under certain process conditions, the surface of the substrate is anodized to form a dense, porous, strong adsorption film.
