Analysis of die casting technology of aluminum alloy

< Strong>Aluminum alloy die-castingis an advanced non-ferrous alloy precision forming technology in the manufacturing industry. It is more and more widely used in the development trend of product precision, lightweight, energy-saving and green, and the demand for die-casting of various materials is also increasing

In the past ten years, the die casting industry has made tremendous development for many times. When the world processing and manufacturing industry has further transferred to the mainland of China, the die casting industry has rapidly expanded in Guangdong, which has rich economic and technological foundation, developed industry and excellent infrastructure. It has rapidly formed a die casting industry intensive area, and is developing at a faster speed, with higher technical standards and higher industrial goals

Analysis of various die-casting technologies:

1. Vacuum die casting technology

The vacuum device is integrated with the host machine, the molten metal is sucked from the die casting chamber, and the operation of the machine includes the vacuum system

2. Touch die casting technology

Stir the liquid metal to obtain semi-solid metal with semi-solid characteristics, then heat the preform with the required size and shape, put it into the die-casting machine, and then perform die-casting molding

3. Flow forming die casting technology

The semi-solid metal slurry with spherical structure is made of ordinary casting metal and is directly diecasted

4. Injection pressure molding die casting technology

The reverse phase solid metal is added to the die-casting machine, heated directly and stirred spirally to form a metal with semi-solid structure. It is immediately injected for die-casting, and first used for magnesium alloy die-casting

5. Pressure die casting technology:

The molten or semi molten alloy is poured into the pressure chamber of the die-casting machine, and the cavity of the die-casting die is filled at an extremely fast speed under the effect of high pressure, so as to realize the high efficiency and high efficiency precision die-casting of the cooling solidification molding of the melt alloy under high pressure

6. Aluminum alloy die casting production process:

Die casting is a highly efficient, non cutting metal forming precision casting method that has been rapidly developed in modern metal processing technology. Compared with other casting methods, die casting production can omit many processing technologies due to its short process, centralized process, good die casting quality, high precision and good surface gloss. Die casting alloy materials, including aluminum alloy die-casting, zinc alloy die-casting and magnesium alloy die-casting, occupy a larger market share and are more used for precision parts of automobiles and new energy vehicles

< Span style="font family: Tahoma, SimSun;"> The production characteristics of aluminum alloy die casting are as follows:

1) The requirements for dimensional accuracy and surface roughness of die casting are high

2) The die casting strength and surface hardness are high

3) For parts with complex shape and difficult to machine, pressure die castings are more suitable

4) With the mechanization of the production process, the degree of automation is becoming more and more common, and the productivity of die casting is very high

5) The assembly work is omitted, the manufacturing process is simplified, the working performance of the die casting is improved, and the energy consumption is reduced
