Aluminium high pressure die casting is a process where molten aluminium is injected into a die cavity under high pressure, resulting in complex and precise parts with high dimensional stability and high strength-to-weight ratio.

What are the common casting methods are ？

1. sand casting Sand casting is a widely used casting method, its principle is to melt the casting materials (iron, steel, aluminum, etc.) into the sand type, after cooling and solidification to form the required products. Its advantages are low cost, wide range of application, but the surface roughness of the casting is high, which is not suitable for precision casting

2. weightless casting wet less casting, also known as gravity casting, is a high performance casting method. The principle is to use the centrifugal force to make the casting material solidified in the space. Its main advantage is that the finished casting has a smooth surface and a high dimensional precision, which is suitable for the manufacture of complex castings and high-quality parts

3. pressure casting Pressure casting is a high efficiency and high precision casting method, mainly used in the production of alloy casting, characterized by high pressure to force molten metal into the mold and shape in a relatively short time. This method has high dimensional precision, smooth surface, suitable for the production of industrial fields requiring high precision parts

4. continuous casting Continuous casting is a high-efficiency casting method. The whole casting process is continuous, so that the casting of high density and small gas content. This method is particularly suitable for making tubular or rod-shaped castings, such as steel pipes, aluminum pipes, etc. Continuous casting has a wide range of applications, and can produce high precision and yield of casting materials

5. low-pressure casting Low pressure casting is an effective casting method. The principle is to apply a low pressure (generally between 0.1-0.5MPa) to the mold to bring the molten metal into the mold from the lower part. The casting material is then cooled so that it forms the desired product. Low pressure casting has excellent yield and good surface quality, especially suitable for casting high temperature alloy, titanium alloy and other difficult casting materials. In short, different casting methods have their own unique characteristics and scope of application. Enterprises should select suitable casting methods according to their own needs and the different characteristics of casting materials to produce casting parts, in order to achieve the best results.
