We are mental mold casting process. Depending on the mold,  the process can be divided into manual mould casting and flip machine mould casting.

Manual mould casting

Manual mold casting, through artificial opening mold. The mold parts is less, so the mold price is lower; Due to the port is small, it can speed up the cooling, and the production efficiency is higher. Compared to sand casting, although belong to gravity casting, but in technology and economy, the mental mould casting has many advantages:

(1) the production's mechanical properties of metal mold casting is higher than sand casting. The same alloy, the tensile strength can be improved about 25% on average, yield strength increases by about 20% on average, its corrosion resistance and hardness also increased significantly;

(2)the casting surface precision is higher than sand mold casting, so as the quality and size stability;

(3)the liquid aluminum consumption can reduce 15-30%;

flip machine mould casting

After liquid aluminum into the mold, the machine filp the mould , which can effectively eliminate gas inside the cavity and improve the efficiency of aluminum liquid filling, improve product quality. Use machine open the mould, it can reduce the working intensity, reduce product defects caused by poor working proficiency. Specific process is as follows:
