摘要:
An injection molding system including a valve operated shooting pot and methods of use are disclosed. The shooting pot may have an inlet and an outlet and a valve may be control flow through both the inlet and the outlet. The valve may be selectively movable between a first position and a second position. The valve may block flow through the inlet and permit flow through the outlet in the first position, and permit flow through the inlet and block flow through the outlet in the second position.
