How to determine the casting surface
During the casting process, the position of the casting in the mold will affect the quality of Precision casting, dimensional accuracy and the difficulty of the forming process. The principle of selecting the pouring position: the important or main machining surface of the precision casting is facing down or side: during pouring, the gas, slag and sand in the mold will float upwards, which may form pores and slag inclusion castings The upper part. Defects such as blisters and the possibility of defects in the lower part of the casting make the tissue denser.
