The cast aluminum parts can be made at will in a variety of complicated styles, and can also make better accuracy requirements, and the surface gloss is also qualified. These characteristics reduce the machining amount of cast aluminum parts and the casting surplus of metal at large layers. It not only saves power energy, metal materials, but also saves labor costs at a large level. It is also because of the advantages of all levels of cast aluminum parts, which are widely used in many fields such as automobile manufacturing, internal combustion engine production, motorcycle production, and electric motor production.

The common use of cast aluminum parts is used for accessories on modern cars. The quality of cast aluminum parts includes appearance quality, internal quality and use quality. Appearance quality refers to the roughness, surface quality, standard tolerance, form and position tolerance and quality error of the casting surface. The internal quality refers to the chemical composition, physical and mechanical properties, metallographic structure and the holes, inclusions and cracks in the casting. Service quality refers to the casting can meet various requirements and working performance

The excellent casting temperature of cast aluminum parts will keep the liquid metal stable, thereby reducing the organizational stress and avoiding cracks. Generally, the casting temperature should be determined according to the type of material and the size of the ingot. If the temperature is not appropriate, it will increase the internal stress and promote cracks or cracks in the casting. The temperature is too low, it is not good, because this will make the surface of the ingot appear cold insulation, slag inclusion and other defects, and even cracks, serious, it will make the casting can not be achieved again.
