The production of aluminum alloy low pressure casting has been increasing year by year, and the market demand for Aluminum Alloy Die casting materials has also been increasing year by year. The production process of aluminum casting in Aluminum Alloy Die Casting part is relatively advanced, which can cast aluminum alloy parts with complex shapes, accurate dimensions, and clear appearances. Widely applicable and rapidly developing. What is cast aluminum alloy? Firstly, grasp the alloy composition and proportion in the Aluminum Alloy Die-Casting process; Note that starting from the procurement of alloy ingots, alloy ingots must be mainly composed of ultra high purity aluminum, followed by ultra high purity magnesium and copper alloy ingots. This puts certain requirements on alloy ingot suppliers, and high quality aluminum alloy materials are often the guarantee of casting quality. To avoid the influence of humid air, the recycled alloy ingots must be placed in a clean and dry storage area to avoid contamination or rust, and to reduce the loss of raw materials. Therefore, the quality of aluminum casting is ensured. A clean factory environment helps to effectively control the alloy composition.
In the production of aluminum alloy casting, attention should be paid to the ratio of new materials to water. The ratio of new materials to old materials is generally 7:3.
The temperature should be strictly controlled, not exceeding 430 ℃, to avoid the loss of aluminum and magnesium.
Why do aluminum casting produce holes? During the casting process, while the metal is still being shaped and solidified, gas will enter the casting, forming circular holes on the surface of the casting. This type of hole will cause trouble for future processing, as it will penetrate into the water. These adverse reactions should be properly addressed during the production process. Adding a certain amount of gas to the casting can effectively accelerate the alloy flow into the mold cavity, reducing the possibility of air entering the mold cavity. When solidifying and shaping, all parts should dissipate heat evenly at the same time to ensure synchronous solidification of the entire metal aluminum alloy casting.
