Precision ast wax is mainly used in aviation industry, civil precision casting, and is also widely used in ships, automobiles, telecommunications machinery, machine tools and other industries.
It is characterized by low gray content and small shrinkage rate, especially suitable for precision casting in the civil field.

Since 1977, due to the vigorous development of China's machinery, electronics, light industry, instrument, transportation and other industrial departments, the demand for casting mold is more and more in quantity, the quality requirement is getting higher and higher, and the supply period is getting shorter and shorter.
High production efficiency: high machine productivity, such as domestic J 3 horizontal cold air die cast aluminum 600~700 times every eight hours; die cast aluminum life, one die cast aluminum, die cast aluminum clock alloy, life can reach hundreds of thousands of times, even millions of times; easy to realize mechanization and automation.
