With the special head shape, this bar is used to extract the partly solidified steel inside the mold til the bottom part in order to withdraw & straighten the unit. The product offered by the company is a radius of curvature that is equal to the casting radius. Also, the strength and rigidity of the Rigid dummy bar is appreciable.
