With the aluminum has been extensively used in aerospace, aviation, construction, transport, transportation, packaging, electronics, printing, decoration and many other defense and civilian (Gravity casting) areas. Aluminum prices, the rapid development and improvement of Chinese enterprises has developed PS plate base, pot material, high-pressure electronic foil, Boeing aircraft forging the basis of high levels of product to fill the gaps in the domestic, import substitution. However, due to the aluminum industry in China started late, small-scale, backward technology, the aluminum industry, not only to face domestic competition, but also to large enterprises with foreign countries, more intense competition, which requires the continual increase in domestic aluminum enterprises investment to promote aluminum fabrication technology rapidly forward, narrowing the gap with foreign advanced level, the competition for survival and development.
Gravity casting is closely related to the amount of casting quality ingots directly with the final quality of various aluminum, the 1990s, especially since the beginning of the 21st century, rapid development and improvement of domestic casting technology, the constant pursuit of "put quality (improve quality), energy (to reduce energy consumption) and impairment (reduce burning), and some even reached international advanced level. But the whole technical level of the cast with the international advanced level, but also there is a gap.
