Precision Casting of Aluminum Alloy for High-Strength and Lightweight Components

Aluminum alloy is an important metal material with high strength, excellent thermal conductivity and light weight.

It is widely used in automobiles, aerospace, electronic products and other fields.
Aluminum alloy casting is to melt aluminum alloy and make parts of various shapes through casting process.

Basic process flow of aluminum alloy casting
1. Raw material preparation. Select suitable aluminum alloy raw materials.
2. Furnace melting. Put the aluminum alloy raw materials into the furnace for melting.
3. Pouring. Pour the molten aluminum alloy from the furnace into the mold.
4. Cooling. After the aluminum alloy fully fills the mold, start cooling. The cooling time and speed depend on the size and complexity of the part. Water cooling, wind cooling, and natural cooling are several ways.
5. Desanding. After the part is cooled, take it out of the mold and perform the desanding process on it to remove the sand shell from the aluminum alloy part. It can be done by giza or sandblasting.
6. Trimming. Trim the aluminum alloy parts after desanding. Trimming includes processes such as removing burrs, flattening the surface, and grinding. To achieve the accuracy and surface of the parts.
7. Heat treatment. For some aluminum alloy parts that need to provide strength and corrosion resistance, heat treatment process is required. Heat treatment includes solution treatment and aging treatment.
8. Surface treatment. Surface treatment of aluminum alloy parts as needed.
9. Inspection. Quality inspection of aluminum alloy parts.
10. Packaging and delivery. Aluminum alloy parts that have passed the inspection are packaged in moisture-proof, shock-proof, and marked manners.
