Abstract: A method of manufacturing a footwear sole component is provided including projecting elongated pins into a mold cavity in the shape of the footwear sole component and partially filled with an expandable material including multiple unexpanded beads, and introducing steam into the cavity through ports defined by one or more cavity walls and through the pins in an internal region of the expandable material, to expand both exterior beads and interior beads in the internal region a predetermined amount. With the elongated pins, the interior beads can be expanded more, less and/or the same amount as exterior beads to provide particular physical characteristics to the component. For example, the interior beads can be fully expanded to a similar density as exterior beads, or expanded less to provide more density and rigidity in the internal region, or expanded more to provide less density and rigidity in the internal region.

Abstract: A method for manufacturing a medical introducer includes placing an introducer sheath onto a mandrel, and overmolding an introducer hub onto a proximal end of the introducer sheath. The introducer sheath has one or more score lines formed on an inner surface and the mandrel has a number of surface protrusions so that when the introducer sheath is positioned on the mandrel, each of the surface protrusions contacts one of the score lines formed on the introducer sheath. The surface protrusions on the mandrel prevent plastic material from the introducer hub from contacting the score lines thereby maintaining the score lines during the overmolding.
