Abstract

PURPOSE: To simplify the diameter reduction of the total core by mloding the rubber ring groove section of the faucet with a die core and the body section thereof with a rubber-like elastic core.
CONSTITUTION: A rubber ring groove 1 and a portion therearound requiring a dimensional accuracy are molded with a die core A and the body section 3 is done with a rubber-like elastic core B. The rubber like core B herein used shall be such that it is expanded in the diameter by the axial compression to match the shape of the inner surface of the faucet body or it is reduced in the diameter by the axial tension force while expaned in the diameter with the release of the tension force. Otherwise, a rubber pack or the like is used which can be expanded in the diameter with the feeding of pressure air force. In the molding, the die core A as reduced in the diameter and the rubber core B are inserted into a plastic pipe heating the end thereof. Then, the die core A and the rubber core B are separately expanded in the diameter.
