The casting process of aluminum casting can be divided into several categories

The aluminum casting process generally melts aluminum directly, and then puts it into the mold for operation to make the shape of the product that the customer wants. It can be said that the use of a wide range, such as machine tools, cars, tractors and many other places. You will use it, but what are the main types of aluminum casting products? The casting process of aluminum casting can be divided into several categories? Here is a brief introduction to the main types of aluminum casting. The main process of aluminum casting includes: metal smelting, model manufacturing, casting solidification, stripping cleaning. The main materials used in casting are cast steel, cast iron, cast non-ferrous alloys (copper, aluminum, zinc, lead, etc.).

How to carry out surface treatment of aluminum alloy casting

Aluminum alloy casting is usually used for the processing of many aluminum parts, and it is also very common in our lives. However, if the surface treatment is not good during processing, it will also have a great impact on product quality. Therefore, we need to pay attention to many aspects when choosing aluminum alloy casting. So what should we pay attention to? Do you know the surface treatment technology of aluminum alloy casting? Let's take a look. The coating process of aluminum alloy casting can be generally divided into spraying, powder spraying and electrophoresis. After the surface treatment of the workpiece, according to the appearance and corrosion resistance requirements of different workpieces, select the appropriate spraying process and equipment, and pay attention to the control of leveling, drying and cooling

What are the requirements and advantages of aluminum alloy castings in the production process

The wall thickness of aluminum alloy castings is called wall thickness, which is an important factor in the die casting process. The reasonable wall thickness of aluminum alloy castings depends on the detailed structure of the precision casting, the function of the alloy, and is closely related to the die casting process parameters. In order to meet various requirements, it is better to have thin wall and uniform wall thickness. Next, introduce the requirements and advantages of aluminum alloy casting reproduction process.

A brief introduction to aluminum alloy casting

Aluminum alloy casting is an aluminum alloy that fills molten metal in a mold to obtain parts of various shapes. It has the advantages of low density, high specific strength, good corrosion resistance and casting processability, and less restrictions on part structure design. Aluminum alloy casting can be divided into Al-Si and Al-Si-Mg-Cu-based medium-strength alloys; aluminum-copper-based high-strength alloys; aluminum-magnesium-based corrosion-resistant alloys; Al-Re-based thermal strength alloys. Most of the heat treatment is required to achieve the purpose of strengthening the alloy, eliminating the internal stress of the casting, and stabilizing the organization and size of the parts. Aluminum alloy casting is generally used to manufacture beams, gas turbine blades, pump bodies, towers, wheels

Why deformation occurs when aluminum alloy casting

In the aircraft structure, in order to reduce their own weight, a large number of thin-walled parts made of aluminum alloy casting materials, but the thermal expansion coefficient of aluminum alloy parts is relatively large, the thermal expansion coefficient of thin-walled parts is thin. Wall aluminum parts are relatively large. The alloy is easily deformed. The deformation in the casting process of aluminum alloy, especially when free forging, requires a lot of processing work, and the deformation problem is more serious. The following is an analysis of the causes and solutions of aluminum alloy casting deformation, hoping to be helpful to everyone.

Heat treatment method for aluminum alloy casting

Generally, the shape of aluminum alloy casting is more complex, the thickness is uneven, the structure is coarse, and the segregation is serious. Therefore, it can only be used normally after proper heat treatment. Typical heat treatment processes include annealing, quench aging, and stable tempering. The purpose of aluminum alloy casting heat treatment is to eliminate the internal stress of the casting. Eliminate the segregation of castings, change the shape of needle-like components in the alloy structure, improve the mechanical properties of aluminum alloy, stabilize the size, structure and performance of parts at high temperature, and improve the workability of castings. The following describes the process of aluminum alloy casting heat treatment.
