Method for Manufacturing Faucet and Faucet Produced Thereby

Abstract

The present invention relates to a method for manufacturing a faucet including the steps of: preparing metallic parts and non-metallic parts, the non-metallic parts having a manifold, and cool and hot water flow path pipes; coupling the cool and hot water flow path pipes to the manifold or coupling the cool and hot water flow path pipes to flow connection members and the manifold; molding the manifold in such a manner as to inject a liquid type ABS resin into a space portion of a double injection mold and to fill the space portion with the ABS resin, so that the manifold to which the cool and hot water flow path pipes are coupled is surrounded with a body; and assembling the body in which the manifold coupled to the cool and hot water flow path pipes is accommodated to other parts constituting the faucet.
