A mold for injection molding of long thin walled articles has precisely balanced high-volume venting of a narrow cavity space surrounding a long slender cantilevered core and minimized flash. The venting is provided by closing an end of the female mold cavity with a sintered metal plug and forming an end of the mold cavity in an end face of the plug.

A resettable mechanical counter having a plurality of number wheels and transfer pinions is mounted in a molded plastic housing in which are integrally formed fixed bosses that index the transfer pinions when the number wheels are reset. The transfer pinions are axially located by means of slots formed in the housing and the number wheels are axially located relative to the reset lever mechanism which itself is axially located relative to the housing to thus position the transfer pinions relative to the number wheels.
