In order to meet the requirement of light weight, the problems of misrun and cold shut can be effectively solved by adding some ceramic foundry sand to the facing sand when producing thin-walled iron castings, and the overcooling structure can be avoided.
4. The drawing property of molding sand is improved obviously, which can reduce the drawing slope of pattern and decrease the sand dropping during drawing, which is helpful to improve the dimensional accuracy and surface quality of castings.
Lost foam casting (LFC) process has been developed rapidly in recent years because of its low investment and low cost.The gating system plays a very important role in the lost foam casting process, an
The V process casting originated in Japan. It uses plastic film to vacuum to make dry sand molding, that is, physical modeling.Because it does not use binder, shakeout is simple and convenient, the co
It has become a trend for foundry industry to move from tradition to intelligence.The typical application mode of intelligent casting is digital foundry, which uses information technology to manage al
