Aluminum is ~3x lighter than steel, and helps reducing vehicle weight. More aluminum die casting parts are installed on car and vehicle, and largely reduce the overweight of vehicle, Lighter fuel efficiency car can saving more fuels and lower CO₂ emissions, improve contaimination of air , and meet a strict requlation of the environment. The lighter electric car can start and speed up quickly, too.
The Cold chamber die casting is suitable for aluminum die casting process. At same time, it also needs high precision high quality steel mold, under high pressure, injecting the molten aluminum alloy into the mold, and cools and solidifies into intended aluminum die casting part, and eject the part out from the mold. Since the molten aluminum alloy has a good ductility, and shape thin walls complex geometries. This just meet some specific requirements of automoble manufacturing.
Aluminum is natrual resist rust, touch the oxygen in the air, and generate Alumina, which cover on the surface of the aluminum part, create a protective film, and stop the other aluminum further Oxidation. The alumina layer has strong corrosion resistance. Aluminum has a nactive thermal conductivity, and can transfer the heat energy into the air and other substance quickly, and remain a steady temperature for automotive components.
Automotive components aluminum die casting is processed by high precision casting die, so its suface is fine. Although a higher shrankage when the aluminum part is cooled, we can control some parameter tolerancy for die casting process and ensure dimensional accuracy of aluminum die casting part. Depends on the texture of surface of die cating part, our engineering team can offer diversity of superiou surface finish for aluminum die casting components.
The common aluminum alloys such as A380, ADC12, A383, offer excellent strength-to-weight ratio and high strength properties. Lightweight aluminum die casting parts can replace traditional heavy duty iron casting parts, and reduce the overweight of the car, makes fuel efficiency car and electric car more benefits . for engine blocks, transmission housings, and structural parts. These aluminum automotive parts are durable.
The aluminum die casting components are sustainable and recycled, similar with our zinc die casting parts in automotive industry. When these automotive components aluminum die casting have been used for a longer time, and lose their functions, they will be recyled, and reused, and melt them and reinject and fabricate the new die casting part or some defective parts reusage. So aluminum casting die components are sustainable and recycled.
