gravity die casting machine with sand core
Compared to sand casting, metal casting has the following advantages:
1.The metal type has large thermal conductivity and heat capacity, the cooling rate of the molten metal is fast, the structure of the casting is dense, and the mechanical properties are higher than that of the sand casting. For example, the tensile strength of the aluminum alloy casting can be increased by 10%-20%, and the elongation is improved doubled.
2.Can obtain castings with high dimensional accuracy and good surface quality.
3.It can produce castings with complex internal cavity structure, such as engine block, cylinder head, wheel hub and so on.
4.Easy to automate and mechanize, high production efficiency
