Air导管

     Generally applied in castings with complex sand cores, where gases in the sand core cannot be readily expelled, leading to excessive gas generation and resulting in the scrapping of the casting. The specific method involves inserting a steel bar into the complex sand core, wrapping a gas vent tube around the steel bar, and burying it within the sand core. This creates an exhaust channel within the sand core, facilitating the smooth expulsion of gases.
