ABSTRACT:
A bowling pin base ring or insert is locked to the outer plastic coating during the process of encapsulating the wooden pin core with an outer plastic covering. The base ring has a tapered annular surface defining a circumferential channel for engaging a portion of the exterior coating. A number of passages extend through the base ring such that gases produced in the coating process and air trapped in the mold are exhausted as heated coating material flows through the passage and bond the coating material to the base ring and to the wooden core.
