Abstract
A shaving head for dry razors in which a perforated shaving foil is connected to a plastic frame is produced by placing the shaving foil in an injection mould and holding it in thermal contact with the wall of the injection mould on one side while the plastic frame is injection-moulded in order to limit the rise in the temperature of the shaving foil during the injection-moulding process.
