Document Type and Number:
WIPO Patent Application WO/2014/196736
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a faucet main body and, more specifically, to a method for manufacturing a faucet main body (10), in which the faucet main body (10) comprises: a hot water flow path (12a) and a cool water flow path (14a) at both sides thereof; a water outlet (16a) for combining the cool and hot water flow paths; a valve (V), formed at the upper portion thereof, for blocking the water flow paths; and a lever for controlling the valve. The method for manufacturing the faucet main body (10), in which each element thereof is divisionally formed using a material in which an ABS resin is mixed with glass fiber, comprises: a step (S10) of separately forming a base body (11) having a valve (V) installed therein, a first assembly (12) having a hot water flow path (12a) and a connection assembly part (12b) formed therein, a second assembly (14) having a cool water flow path (14a) and a connection assembly part (14b) formed therein, and a third assembly (16) having a water outlet (16a) and a connection assembly part (16b) formed therein, and then inter-combining the connection assembly parts (12b, 14b, 16b); a step (S20) for doubly injection-molding each exterior molding (22) in a manner of overlaying the exterior of the base body (11) and the first to third assemblies (12, 14, 16), which have been combined, with an ABS resin composition melted to have a temperature of 190 to 210 ℃; and a step (S30) for plating the external surface of the exterior molding (22) with nickel-chromium to prevent damage thereof. The faucet main body according to the present invention provides advantages in having durability due to remarkable coalescence among the base body and the first to third assemblies caused by injection-molding the base body and the first to third assemblies using a material, a mixture of an ABS resin and glass fiber, which is resistant to corrosion and is not prone to deformation, and doubly injecting the exterior molding on the exterior thereof using a single ABS resin composition material, and also in reducing the manufacturing costs and lowering the sales costs by remarkably decreasing the weight of the faucet to one quarter compared to a common faucet manufactured using a conventional brass material. Furthermore, since the faucet main body of the present invention is manufactured by performing injection-molding using a resin and plating using nickel-chromium, the faucet main body according to the present invention provides advantages in remarkably reducing working man hours and enabling manufacture of more varied faucets. Moreover, since the manufacture of the faucet main body according to the present invention does not use the conventional brass material at all, the faucet main body of the present invention has advantages in improving the poor environment of casting-molding using the brass material, and in enabling that no harmful component is detected when the faucet main body is applied to a faucet and used.
