Aluminum die casting is a part of pressure casting. It uses the pressure casting mechanical die casting machine equipped with the casting mold to pour the heated liquid aluminum or aluminum alloy into the feed inlet of the die casting machine. After die casting by the die casting machine, aluminum parts or aluminum alloy parts with limited shape and size of the mold are cast. No such parts are usually called aluminum die castings. Aluminum die castings have different names in different places. In this guide, we talk about how can aluminum alloy casting industry reduce energy consumption.
Because the metal aluminum and aluminum alloy have good mobility and plasticity, and the casting process is cast in the pressure die casting machine, the aluminum die casting can make a variety of complex shapes, and can also make high precision and brightness, so as to greatly reduce the machining amount of castings and the casting allowance of metal aluminum or aluminum alloy, which not only saves power metal materials, but also greatly save labor costs. Aluminum and aluminum alloys have good thermal conductivity, small specific gravity and high machinability. Therefore, aluminum die castings are widely used in automobile manufacturing, internal combustion engine consumption, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, fine instruments, landscaping, power construction, architectural decoration and other industries.
Aluminum die castings can be manufactured into aluminum die-casting auto parts, aluminum die-casting auto starter pipe fittings, aluminum die-casting starter cylinder, aluminum die-casting gasoline engine cylinder head, aluminum die-casting valve rocker arm, aluminum die-casting valve support, aluminum die-casting power parts, aluminum die-casting motor pot cover, aluminum die-casting shell, aluminum die-casting pump shell, aluminum die-casting building parts, aluminum die-casting decorative parts Aluminum die-casting guardrail accessories, aluminum die-casting aluminum wheels and other parts.
It is an important and urgent task for all countries to reduce energy consumption, reduce environmental pollution and save limited resources. With the promotion of the general trend of lightweight products such as automobiles, the aluminum die casting market will develop greatly in the next decade. The proportion of aluminum and magnesium alloy castings in major casting consuming countries is between 13-19. In some countries, it is as high as 30% – 40%, while the proportion of aluminum and magnesium alloy castings in China is less than 10%. More than 90% of aluminum castings in prosperous countries are used in automobile parts manufacturing.
In China, there are still many problems to be solved in order to form a wide range of consumption of aluminum alloy castings and meet the requirements of automobile lightweight:
1. 1. The requirements of automobile for aluminum castings are carried out in the direction of thin wall, complex shape, high strength and high quality. In order to meet this request, the casting process should be further optimized and the development of new alloys should be stopped.
2. Design and technology, such as using a variety of technologies and automation technologies to improve consumption rate, prolong the service life of dies, and reduce the number of parts by integrated design.
3. Adopt computer imitation technology to shorten the development cycle of the process.
4. Increase the recovery of aluminum. Recycled aluminum is the main material of aluminum casting. Our colleagues in the casting industry should pay attention to the application of recycled aluminum resources, develop the technology of effectively separating aluminum from fertilizer combined with composite data and heterogeneous data, and establish a universal fertilizer recovery system.
