Abstract
A sealing member for a powder slush molding apparatus includes an elastomeric main body comprising a head portion, an anchor portion, and a neck portion extending between and joining the head portion and the anchor portion. The head portion of the sealing member defines at least one interior channel that is centered on a midline of the elastomeric main body and which has a polygonal sectional shape. The polygonal sectional shape of the at least one interior channel, and its location on the midline, permits the head portion of the sealing member to attain a measure of compressibility that helps limit the force needed to compress the head portion without rendering the sealing member too flexible that it cannot adequately retain its shape. The sealing member is useful in establishing a seal between a shell and a powder box of a powder slush molding apparatus.
