ABSTRACT:
A bell cup includes an interior defined by an axially rearward metal back region, an axially forward metal discharge edge, and a metal side region extending from the back region toward the discharge edge and terminating at the discharge edge. The back region includes a port having a forward end through which coating material to be atomized is supplied to the interior, and a metal intermediate portion between the forward end and the side region. The intermediate portion is oriented axially further away from the discharge edge than the forward end is axially from the discharge edge.
