Research of Blasting Cleaning Thread on Engine Cylinder Body

When general core paint is utilized for producing 4JB1 automobile engine cylinder,a large amount of adhering sand will be generated in engine cylinder lid,which thus will lower thermal conductivity of the cylinder and accordingly bring forth numerous negative effects.The experiments and researched have shown that better effects can be achieved if the reasonable blasting cleaning process is adopted for removing adhering sand inside 4JB1 automobile engine cylinder casting.
