Aluminum die-casting is a commonly used metal die-casting process for manufacturing aluminum alloy products. It injects molten aluminum alloy into a metal mold and applies high pressure to solidify the aluminum alloy into the desired shape and size in the mold.

Dalian aluminum die-casting has the following advantages:

1. High precision: Aluminum die-casting can produce high-precision and complex shaped aluminum alloy products, such as automotive parts, electronic equipment casings, etc.

2. Rapid production: The aluminum die-casting process can achieve efficient production speed and greatly shorten the manufacturing cycle.

3. Thin wall casting: Aluminum die casting can produce thin-walled and lightweight aluminum alloy products with good strength and rigidity.

4. Good physical properties: Aluminum alloy has good thermal conductivity, conductivity, and corrosion resistance, suitable for various application fields.

5. Recyclability: Aluminum alloys are recyclable and meet the requirements of sustainable development, which is beneficial for environmental protection.

The process flow of Dalian aluminum die-casting includes:

1. Mold design and manufacturing: Design and manufacture metal molds based on the shape and size requirements of the product.

2. Aluminum alloy melting: Heating aluminum alloy materials to a molten state, usually using an electric or gas furnace for melting.

3. Injection and pressure application: Inject molten aluminum alloy into the mold and apply high pressure to fill the entire mold with aluminum alloy.

4. Cooling and solidification: Cooling and solidification in the mold to solidify the aluminum alloy into the desired shape.

5. Mold opening and removal: Open the mold and remove the solidified aluminum alloy products.

6. Post treatment: Carry out post treatment processes such as deburring, polishing, and spraying on aluminum alloy products to improve their surface quality and decorative effect.

Aluminum die-casting is widely used in industries such as automobiles, aerospace, electronics, and home appliances. However, aluminum die-casting also has some limitations, such as high mold manufacturing costs and difficulty in achieving certain shapes. Therefore, when choosing the aluminum die-casting process, it is necessary to comprehensively consider factors such as product requirements, cost, and production efficiency.
