A mold for forming elastomeric articles and the like, has vent plugs inserted in bores through the body of the mold. The vent plugs may be manufactured of sintered metal. Each vent plug has a bore therethrough that is significantly smaller than the bore through the mold body, so that very little, if any, of the elastomeric substance being formed in the mold flows into the bore of the vent plug.
