A method of manufacturing a mold core for a concrete product mold, the method comprising the steps of:
- forming a mold core by welding together metal wire into the shape of a mold core including a ventilation opening, and into the shape of a vent body that integrally extends from the mold core from around the ventilation opening;
- and
- forming at least one vent hole into the vent body by inserting a cutting tool through the ventilation hole and causing it to cut through the vent body;
- and
- smoothing surfaces of the welded-together wire, which are positioned to shape a concrete product in the mold.
